The World’s Most Efficient Air-Conditioner

Well, I’m finally done building that fence I’ve been meaning to build for the last few years. It came out great, and now we at last have the nice, private yard that this house of ours deserves. But as with every do-it-yourself project, other unexpected benefits were revealed as well, and one of them was that I ended up with a free air conditioner of unsurpassed efficiency.

To get this fence built Mustache-style, I didn’t whip out my cell phone and credit card and call a fence contractor. I had to do it myself, and since it was my first large-scale fence (about 180 linear feet at 6 feet of height), I kept track of some of the stats.

I had to set 25 posts of treated lumber into the ground. The posts were each 8 feet long, weighing 30 pounds each and set into about 80 pounds of concrete. Of course, before setting each post I had to carefully line up and carve a 2-foot-deep hole in the rocky, dry Colorado hardpan soil. Each of those 80-pound piles of excavated soil and rocks was the result of several minutes of wrestling with a very powerful electric drill equipped with a 3″ soil auger, followed about 100 blows with a manual post-hole digger, and occasional attacks with a sawzall to cut through roots, a diamond blade grinder to cut through concrete, and a handheld jackhammer to chip away anything that remained. And all those holes were just to get me to the point of hand-mixing over 2000 pounds of concrete, manually tailoring, drilling and screwing over 100 cross pieces, and nailgunning in 500 cedar planks, cutting and bending each to coax their naturally-curvy demeanor into the extremely tight and straight fence that I wanted.

All in all, it was about 69 hours of work, and it was done through a period of record temperatures in my area. Some days topped out at over 100 degrees Fahrenheit (37C), and few were below 80. Half of the fence is in full sun, leaving me with only SPF 80 sunscreen and my sun hat for shelter.

But a strange thing happened as the days went on and the fence sections were completed, one after another. I stopped noticing the heat, and started feeling downright comfortable. The improvement was so dramatic that I thought it was the weather that was changing rather than me. Often I’d walk past my outdoor thermometer on the way to refill my water mug, and be shocked to see another mid-nineties reading, when I felt like it was under 80. And at the end of each day, I’d find myself inside the house feeling comfortable even with a shirt on, noticing an indoor thermometer reading above 85. In previous years, I had felt the need to turn on the air conditioner at around the 80 mark. Morning house temperatures in the high 60s suddenly felt bone-chilling to me, even though in the winter I normally curse the stuffy house and go outside to get some fresh air if someone turns the thermostat above 67.

What I had done with all this work in the heat is given myself the gift of Heat Acclimation. This is a form of Badassity that is not just something made up by the most spartan of Mustachians. It’s a real and scientifically measurable body adaptation – a gift of comfort that YOU should give yourself this summer, because the benefits are enormous.

To get some of this goodness for yourself, it helps to understand what it is.

When a normal office worker encounters unusual heat, his body tries to cool itself by sweating. The body also circulates heated blood out near the skin’s surface, allowing heat to radiate and convect through the skin and evaporating water. That’s why overheated people often appear more reddish in color.

The problem is that this leaves less blood in the core of the body where the muscles are working, and it requires a higher heart rate for any given volume of work. In short, you slow down at whatever you are doing, and if you push too hard you start feeling like shit and just want to lie down in the shade.

But when you’re out in the heat, your body is starting to wise up to the situation. It creates more blood, the endurance of your sweat glands increases, and the ability to sweat efficiently at the first sign of heat increases. You really do become a Badass Heat Survival machine, and research indicates that you’ll see significant results within just one week of spending an hour or so outside in the heat doing light exercise like walking or biking. I’d estimate that my own acclimation has sliced about 12 percieved degrees Fahrenheit off of this summer’s heat.

The more you do it, the better you get, as witnessed by the Phoenix-area MMM readers who insist that they can easily bike to work year-round in that hot desert city where daytime highs are rarely below 40C (104F) for months on end. This also explains the amazing abilities of my Mexican concrete subcontractors back in the house-building days. These guys would often work alongside me on searing-hot days in black jeans and long-sleeved Denver Broncos sweatshirts, while I could barely survive with a white t-shirt, dark sunglasses, and enormous straw sombrero.

In other words, when someone says, “You can’t spend time outside where I live, it’s TOO HOT!”, it’s really equivalent to saying, “You can’t bike to the grocery store where I live, IT’S FOUR MILES AWAY!” – it’s not a question of impossibility, just of acclimation.

But this post isn’t really about extreme heat survival, like those 120F Phoenix days. It’s about a much easier and more relaxing kind of heat acclimation – making the most out of your own climate in the summer months.

During the peak of the last hot season, I wrote a rant called “How Not To Use Your Air Conditioner“, where I railed on the excessive use of A/C by modern people. This year, I’m doing it again, but with the added perspective of this new experience of extreme heat acclimation, because it works better than I thought.

Here’s an interesting fact: because my house is fairly well insulated and captures a lot of winter sunlight, it acts as a significant buffer against weather changes. I’ve measured that even without a furnace and with no air conditioner, the temperature in here would never go below 40-50F in the winter, or above 86F in summer. In other words, if I were badass enough to put up with the full range of those temperatures, I could run with zero heating and cooling costs indefinitely. 100% of my costs (about $450 per year) are to fine-tune that temperature to allow my family a more luxurious lifestyle.

So as your wimpiness increases, so do your heating and cooling costs. At the extreme end of the spectrum, some people are such heat wimps that they cool their house to the meat-locker temperature of 72F in the heat of summer. You can spend $200 per month keeping a house that cold, even while the house’s natural temperature without cooling might be barely above 80.

Gaining heat acclimation in the summer (and cold acclimation in winter) is about more than just utility bills. It also opens the world back up to you, allowing you to get out and do things that you’d normally wimp out of doing.

A common lament across America these days is this one:

“I know Mr. Money Mustache taught me I have to get my groceries with a bike trailer, and I’ve been doing it all spring. But now it’s just so hot out there, and he doesn’t know where I live so he won’t see me… so I think I’m just going to sneak out and use my air conditioned car until the hot season ends”.

When Junior Mustaches pull stunts like that, they think they are fooling Mr. Money Mustache, but they are really just fooling themselves. Riding around in your climate-controlled car is just like taking another shot of heroin to prolong a lifetime habit. Instead, you can kick the addiction to comfort, go through the necessary downtime, and be free for life (see: Trainspotting).

So let’s just try this experiment: get yourself out in the heat for at least a few minutes every day. Not just walking to the car, but seriously out in the heat. Go for a walk, try a run if you’re a runner, bike to work, even go out fishing. Drink loads of water (during my fence work I went through about 4 32-ounce jugs of icy water every day). And eat a banana or two to help replace electrolytes lost through sweating.

Instead of increasing your suffering, you’ll actually be building your ability to stop suffering. Take it up to an hour a day. Increase your A/C temperature by one degree every day or two. Watch your need for air conditioning drop drastically. Watch your enjoyment of the outdoors increase. Watch your Money Mustache grow.

A cautionary statement, not that people like MMM readers need these things: heat CAN be dangerous. Your body does need to keep its core temperature within a certain range, otherwise bad things happen. As physical fitness decreases and age increases, so does the risk of overheating. That’s why when record heat waves strike, you always read about a bunch of elderly people kicking the bucket in their non-air-conditioned apartments.

On the other hand, if you carefully and gradually push your comfort boundaries, just as with any form of other exercise or badassity training, you tend to extend those boundaries in a positive way. I try to spend at least an hour a day doing something at least mildly uncomfortable. Just as I once suggested that we should all learn to appreciate mild hunger, it is also nice to appreciate mild discomfort. Without it, you are on the slippery slope to lifetime wimpiness, a place much worse than mild discomfort!

I can see it’s back up in the nineties outside there today. Full sun and no wind. It’s far too comfortable down here in my basement office, so I’m going out for a ride!

    Awesome post MMM! My wife and I haven’t used A/C in our home or our vehicles for 2 years, and it’s the best move we’ve made for growing our Money Mustache! We get to save $$ on utilities and BONUS: we can also poke fun at all of the wimpy A/C users. Aw yeah.

      Same here. My utilities and water are about $40 month.
      I have a renter living in the same size place and his utilities are typically $150 monthly. He usually can’t believe how much he spends on it each month, but walking into his place it’s freezing cold and he has a window cracked. Some people are clueless.

      GREAT Article! and here’s another tip we learned in Thailand from locals, right after we arrived and had spent a few days ‘dying’ from the heat: you feel like crap because of eating too much fat which makes your blood thicker, sluggish. So cut down to fruits juices light stuff, and throw in some spicy chilis/ hot curry, which thins out your blood and makes you feel better. Worked like a charm for me and I enjoyed the rest of my time there without A/C!

      Above about 40 mph (depending on the vehicle), it is actually more fuel efficient to use your car’s A/C than to open the windows all the way, because of the added drag.

      Though if you’re doing it because you don’t have A/C in the car or don’t want to shell out the $$ to repair it, then more power to you!

    True badassity at work here! And absolutely true. When I worked from home I would go weeks with little exposure to air conditioning. And I adapted fairly easily to heat and humidity. Working in air conditioning now really does affect my adaptation. And let’s not forget the cultural “requirement” of never, ever sweating…

    • Knince June 14, 2012, 12:07 pm

      I feel your pain Sara! I have to wear a fleece jacket in the office during the summer thanks to the 72 degree thermostat… brrr. To coworkers that think I’m crazy, I point out that humans have survived without those dang air conditioners for many many years.

      Also, I spent some time in Manila, Philippines and so I can reinforce your comment that “no-sweat” is definitely cultural. Most people there don’t have home air conditioning, and they live on the freakin’ equator! Yet, they hardly sweat and just carry an extra shirt to change into if needed.

      Definitely hardcore.

      Yeah – the worst is the excessive air conditioning used in public places. I was at a pub the other night (with an Australian MMM reader actually), and we noticed it was ice cold in there (probably 72F or so) after it had been a 100F day outside.

      This is just making the eventual heat feel worse for the customers. Instead, why not set the A/C to just cool enough to be comfortable, and scale that as the summer heat rises. So in Phoenix, buildings would be cooled to 86 since everyone is coming in from temperatures of 110 – it would still feel very refreshing. Here in Colorado, you might cool to 82 or even 80. But 72? That’s just impractical.

      Meanwhile, I’ve noticed a tradition in Hawaii of fairly minimal A/C use compared to the mainland, despite a fairly hot and humid climate. The culture is just slightly different such that people are willing to let their bodies do the air conditioning.

        I HATE walking into a store or office building from 110 degrees outside temperature and having it feel like winter inside. It makes me physically tired–I think the repeated stress of adapting to wide temperature swings is very hard on the body.

        Hawaii is usually better with the little retail stores, but in Honolulu at least they still tend to go Antarctic in the larger malls.

          Working at an overnight summer camp near Houston, I learned a few things about how the heat affects me.
          1) It generally took me about 3 days to get used to it after living indoors. Getting used to it included learning to sleep on my back. I would have expected side-sleeping to be cooler (more exposed surface area), but no.
          2) Being in my mom’s house during breaks from summer camp generally took about 6 hours to get used to.
          3) None of us got sun tans because we stayed in the shade whenever possible (in other words, whenever we weren’t swimming or canoeing).
          4) Being in the sun (canoeing) with no hat = getting a headache. Admittedly, I only tried that once. I don’t know if the brain can get used to being deep-fried.
          5) Moving to grad school in Austin directly from summer camp one year was difficult. Austin is much less humid, but my campus had much less shade and much more concrete than my camp, and all the buildings were refrigerated. (Sadly, I now work in these refrigerated buildings.)

          I find it hard to believe that being outside only an hour a day can make such a big difference. Maybe it was because you were also using less AC as you went along.

        I wouldn’t say Hawaii is hot or humid. I mean with temps ranging from 72-85 and humidity around 55% I wouldn’t consider it a great feat for not using A/C there.

          Back in 1968 when I was a pre-teen we lived in Navy housing for a year. The houses had no heaters, no air conditioners and no insulation. The exterior walls were 3/4 inch thick boards. We had a huge screened-in lanai and it was comfortable year round.

        Ha, the alfresco dining scene on Pearl St Mall last night was right on the money, but that would have needed a car…

        Great article and I’ve observed the same when we lived in Perth, Oz (dry, v.hot long summer). From my personal observation it doesn’t seem to work quite so well in a crazy humid environment as it is a lot harder to shed the heat, but obviously many people do function ok.

        As an aside, one of my pet hates when I’m on the road for work is being sealed up in a hotel room with windows that are glued shut. It would be nice if TripAdvisor showed who lets you breathe at night.

        Hawaii is warm, not hot. The temperature is very, very constant in most places. For instance, if you look at Honolulu, the average high for today’s date is 87 and the average low is 72. That’s warm! But the record high is 90 and the record low is 67. Not much different, and not hot. It just doesn’t get hot, the ocean very strongly moderates the temperature. Sure, depending on where you are on the islands, you might get more or less variation. And most mainlanders wouldn’t think twice about turning on the AC if it’s 85 degrees every single day. So, yeah, there’s definitely a cultural difference and we could learn from them. But getting by without AC when it’s 85 every single day is a little different from getting by without AC when it’s 95 some days.

          Exactly! Tell that to the Great Lakes and North Atlantic Coast regions, please, where people run their A/C on 79F days, just so the house can stay 72.

            We took advantage of our neighbors A/C usage and the layout of our properties. Essentially our patio/backyard is all the space between our house and theirs. The drip line for their central unit goes out into our patio. We just put a bucket there and used the water to keep our plants healthy during the spring. The strange thing is we noticed this happening when it was still 75F outside.

            We still do not know if our A/C works, it’s a central air unit and we haven’t turned it on all year. We moved in the winter so our house inspector couldn’t test it either.

            I have a friend who tries to keep his office 72F and has electric bills all year of $200-$300 (electric heat also). Our house on the other hand has hit 86F once after a night that we got the house down to only 65F. So far it’s been since August and I haven’t even had to open the windows to keep it cool.

        MMM, I’ve always assumed for-profit public places (e.g. the pub you were at) consider it a competitive advantage to keep places ultra-cool. Consider that the average non-Mustachian consumer is on a downward spiral of hedonistic adaptation. Why not cater to this and keep the place cooler than the competition? I suspect that a lot of marketing research dollars has determined that most people will find a certain temperature (e.g. maybe it’s 72) most comfortable.

          Having worked for a restaurant franchise in the past, you are correct, but not in the way you think.

          One reason business keep the places ‘too’ cool is to keep people from staying too long. Same with the seats, don’t want them too comfortable. Same with background music. Just a little too loud to make people just a little uncomfortable.

        Agree, but we noticed that even in the winter a lot of restaurants are cooler – and it drives me nuts. Finally ran across the reasons why – if it’s colder, you are more likely to eat more/order more = they make more money. (I noticed Applebees to be the biggest offender in my neck of the woods) I usually just bring a coat now, but Jeez, do I get ticked (at myself) when I forget!

          In Taiwan it can be hit and miss. At least half the places I eat there are no air conditioning, and that is excluding the ones that are the equivalence to a hot dog vendor. Most actually just run fans. The shaved ice shops do pretty well there.

          When you get into the bigger restaurants, ones where you have wait staff and such, then you get into a fairly consistent air conditioning environment. This will vary between being comfortable at around 80F, or being chilly at 72F.

          Then you have all the clothe stores which seem to blast their A/C with no worry of waste. Some shops even have large glass doors propped open with the A/C on full.

          There is also the food market which is housed in an open fashion, basically a large structure with a roof, but no A/C and plenty of vendors on every side of the street making it nearly impossible, and I say nearly because some do squeeze through, to drive a scooter, let alone a car, through. This market is open every day, and was the place we went for the majority of our food.

    Human body can for sure endure whatever the condition throwing at them… I grew up in China so “what is air condition?” I remember those 44 degree days (probably well above 110F) and when I woke up from my nap, my bamboo sheet was soaked with sweat.. but you live..

    I think anybody can do the 90’s… (actually if it were 90’s, it felt cool!! with breeze? that’s heaven!), 110 is a different story since you could hardly breathe, but you make it work.. :)

    We never had AC in China so at night, every kid came out to the Ally and we sat in circles to exchange stories or listen to some stories on radios together.. It really did wonder to bond human beings.

    I have been leaving the A/C off on my commute for the past couple of weeks and it is doing good things for my heat tolerance AND my gas mileage. But I also have a habit of taking a walk around midday, no matter what the outside temperature is (I’m one of those Phoenix residents so it’s quite hot!), so that helps too.

    And yes, MMM, I know I need to stop driving my car to work. :-D I’m working on it–looking for a scooter and a replacement for my old bicycle. It’s a nice bike but it’s an older road bike with very low handlebars and downtube shifters, which kills my neck and shoulders if I ride it more than a mile or two (I have some chronic neck issues from an injury in high school). Once I get something that has a more upright seating position I’ll start working up to bike commuting. Hopefully I’ll find a decent scooter soon too which would be a great compromise. I’m not sure I’m Badass Enough to start biking a 30-mile round trip commute in the middle of the summer–that might have to wait for cooler months so I can work up to it. Just have to convince my wife to let me sell the truck to pay for it! With what our truck is worth we could get an ’04-’05 xA, a utility trailer for it and a 50cc scooter and probably still put a little cash in the bank.

    And yes, I also know we need to move closer to work. Working on the wife on that score too. Moving is very stressful and she doesn’t want to do it, but we’ve got 9 months left on the lease and I’m sure she’ll come around by then.

      <—-PHX resident too. Also my main bike is an old road bike with downtube shifters. I love it! It could be that the bike is too small for you? But the nice thing about those old road bikes is you can switch to mountain bike riser bars fairly cheaply because you don't have to replace the shifters. If you are in downtown area go to the Rusty Spoke bike co-op or if you are in the east valley you can go to Bike Saviours bike co-op. Or heck I could help you out :) and get you biking in no time! I have some old parts lying around although not the nicest quality could get you in that more upright riding position.

        I hate the downtube shifters. I tried to get used to them and found that I ended up leaving my bike in a middle gear all the time because it was too much hassle to reach way down to shift all the time. It made me feel unstable, and I really don’t like taking my hand off the bar where I can’t brake on a moment’s notice if needed. I want a bike with integrated shifters on the handlebars.

        The bike is not too small–I have the seat height adjusted to where my legs get proper extension and the pedaling mechanics are fine. It’s just that all road bikes seem to have very low, forward handlebars–and my neck and shoulders can’t handle the stress well for long periods. I get bad headaches. So I want something configured more like a commuter bike, with a comfy rise to the bars, and shifters easily at hand. I might just take the opportunity to learn to build my own bike from components–which is something I’ve kind of wanted to do for a while anyway–and then I can pick everything just the way I want it. :-)

        Thanks for the offer of help though! I might just take you up on it if you’re not careful… I am near downtown, in the Coronado neighborhood.

          One nice thing about biking in Phoenix is it’ so flat you really don’t need to change gears that much. But I can understand the love/hate with downtube shifters. You’re only a few miles away. I’m in North Park Central Neighborhood. Contact me through my blog if you want to get together sometime and tinker on your bike.

    Oh man, before this post, I would definitely have been one of the Junior Mustacians who was fooling myself. I lived in Phoenix for 24 years, and never really got used to the extreme summer heat. It was one of my primary reasons for Getting The Hell Out Of There. Looking back, I guess it could have been my extreme hatred for the heat that led me to keep suffering (because I was always avoiding it). Upon my return, I shall have to embrace discomfort, in order to become comfortable…as much as that still sounds bat-shit crazy to my whinypants heat-weakness. DAMN IT!

      There are many, many other reasons not to live in Phoenix besides just the heat. The complete un-sustainability, its giant sprawling cancerous growth, and sheer ugliness are all good enough reasons for me. We’re getting outta here as soon as we can manage it.

          PHX isn’t as bad as you make it out to be. There are some downsides (just as any city) as mentioned but so many positivies if you are willing to look for them. Granted I would love to move to California but the cost of living here is so affordable and i have never had any problems finding a new job. You do not have to be a part of the urban sprawl. Tempe or downtown Phoenix are great cities. Plus Sun 300+ days a year, great culture and ever improving biking infrastructure.

          Thousands of people don’t come here to retire for no reason. This is a great Mustachian City that is starting to more forward thinking.

    I just got back from visiting my mom in the Cincinnatti metro area. She has a nice house out in the suburbs, with nice big trees and a breeze that goes through.
    Bedtime the first night I wanted to open my window for fresh air, but she said the window had been stuck and not opened for over 2 years. So I investigated, and within 20 minutes we had that sucker opened. She kept offering to just put the air on for me, but I couldn’t see the point, since it was in the 60s outside!
    The next day, she was telling me about how she’d love to enclose her back patio into a room so she could sit out there. Well, she had a perfectly nice set of table and chairs out there, plenty shade for the daytime, and in any case she never opened the shades in her house much less the windows! Hell, if she’d replace her storm door with a screen door for summertime at the front of the house and open the back she could have gotten a really nice cross-breeze and probably drop the internal temps 5 degrees!

    Back at home in SoCal, we almost never run the AC. Maybe 2-3 times all summer. I’m perfectly happy to change into lighter clothes and sip an iced tea in the shade, or jump in the pool if it gets really bad. One year we discovered that it costs over $10 in electricity just to run the AC overnight. Worth it if we have guests, but not for just us!

    I might be a wimp or complainy-pants on this one. I hate the heat although I seem to be able to handle cold temperatures better than most people. Our electric bills don’t seem that expensive though. They usually run about $50/month in the summer. We have one of those programmable thermostats that basically doesn’t cool the house between 8am-5pm and keeps it at 72 when we are home.

      I agree. I had my DNA snps sequenced, and discovered that both my maternal and paternal lines are all from extreme northern points in Europe (Tunguska Siberia!). I have NO problem with the cold, but heat has always been a BIG issue for me. So, I use airconditioning at a reasonable setting (76ish) without embarrassment – so there!

    I totally see your point Mr. MMM. I recently started running mid-day due to schedule reasons and was very reluctant at first. In Southern California it can get as high as 90’s at that time of day, and I was used to running first thing in the morning when it was nice and cool. I decided either I be a lazy slug or I just get up and run in the middle of the day. What a difference!!! It’s only been about 2 weeks and my body has already adjusted to the hot temperatures during the hours of noon-2pm! It’s like I retrained my body and built up my heat tolerance! I agree, no more Mrs. Complainy pants here……….it’s a decision to get past the difficulty of adjusting the first couple of days and I think it went smoothly ;)

    My father in law was visiting a few weeks ago and when the house hit 80F, he went and turned on the A/C. Seeing that it was 6PM and the cool Colorado night was about to come upon us, and also because my wife and I like to torture his anti-Mustachian spirit, she snuck back over there and turned it off. I was so proud of her!

    A few minutes later, as I was wrapping up some work and my wife was working on dinner, My father-in-law once again went back over to the thermostat to check the thermostat, checked the temperature, noticed the A/C was off again – and so he turned it back on. At this point I called him out as being a wimp and let it be – he was leaving soon anyways.

    On an aside….

    Later that night, he laughed at my wife and me for buying and selling things on Craigslist. So I laughed at him for still working full time at 65 at a job he doesn’t enjoy. We have great relationship. :)

    MMM – It’s worth pointing out that cold acclimation also exists. Coming from Texas to Colorado, I had the heat part down but not the cold. But a winter of riding my bike to work and I’m now an eskimo compared to the lifelong Coloradians in my office.

      True, and I acclimate to cold better than to heat. We do need to remember that people lived in those too hot/cold areas long before A/C was invented.

      I almost never use A/C in a car, because to me it is just so darned uncomfortable to have the cold air blowing on you, while parts of your body near the windows & roof are still hot. One trick for the really hot days is to carry a spray bottle of water. Spray the dash, steering wheel, and seats before getting in, and give yourself a spray now & then.

      I don’t use home A/C either, but that’s because of good insulation, and an intermountain climate that cools into the 50s even on days when the high tops 100.

        There are inherent physiological differences between people, though, and I for one have had little success altering mine.

        I also grew up in Texas; I don’t know whether to attribute it to nature or nurture, but I deal with heat very well. I think 85F is perfectly comfortable; I’m usually the last person in the room to break a sweat.

        But even after 22 years in the north (2.5 in Chicago, 2.5 in NYC, 17 in Seattle), I am STILL not acclimated to cold. We don’t heat the house above 68F, but I require supplemental electric heating pads and space heaters to get by.

        At least part of it is identifiably medical — I have a moderate case of Reynaud’s disease, which is a circulation problem in my extremities. Temperatures below about 55F are painful, sometimes excruciatingly so. Digging something out of the deep freezer is like sticking my hand into a gom jabbar box.

        Oh, and my resting body temperature is about 1.5-1.8 degrees below ‘normal’, and has been my whole life. Don’t know if that’s related.

        Conversely, even after all those years I take to southern heat like a duck to water. ‘Use it or lose it’ hasn’t happened for me at all.

        I think temperature acclimation is a worthy goal, and if it works for you, great. But my experience leads me to believe that it’s not always something one can control.

          It’s probably worth splitting out endurance/toughness (how a lot of posters are interpreting all this) and the actual physiological adjustments that your body makes, if you let it — most of which, apparently, have to do with capillary blood flow near your skin. Karawynn, you’re good evidence of this — in effect, your body and bloodstream are permanently set to heat-loving! I hope that, long-term, FI lets you plan your life for comfort — a permanently warm climate, or summers north and winters south.

    I built 365 linear feet of fence around my house in the worst of the Alabama heat last summer. I did save 75% off the lowest quote I got from a fence builder by doing it myself.

    But the heat didn’t have the same effect on me. I appreciated our air conditioner more than ever afterwards. I consider it a small triumph that I currently have our a/c set at 74 this summer instead of 72 like last summer.

      I guess that’s not so bad – if you adjust upwards by one degree a day, you’ll be at a reasonable setting in only 10 days.

      I think the reason you didn’t get the same benefits from working in the heat as I did is that you drowned it out with excessive A/C each night. The idea is to do these high-heat exercises, and then use the extra conditioning to allow you to make the rest of your life warmer as well, while remaining comfortable.

            I wouldn’t even consider myself close to junior mustachian and I refuse to run AC for anything larger than 200 sq feet. If the weather gets ‘really’ bad, I find the most efficient room in the house, lock it up and throw in an efficient window AC unit (which I haul out from the attic). In our house, that happens to be a “theater room” which has only one window, a door to a finished garage (second coolest room in the house), no south or east facing sun-accessible walls and a double-wall structure (for sound deadening reasons). The sad part is that then we usually run a lot of heat-generating appliances (projector/speaker/receiver/player) for entertainment that fight against the AC unit so it has to work harder.

            I’d rather like to know how someone would even keep 3400 sq feet clean. I can’t even imagine.

      Yes! When I was in college in the mountains of NC, during the winter we would have long stretches of highs in the 20’s. Of course when it’s 25-30 degrees outside, you bundle up and walk to class in the snow. But in the spring, when it hit 45? Shorts weather! Then I moved to Louisiana and think I need a jacket when it gets down to 50 in the “winter.” The cold acclimation might not be as scientifically demonstrable, maybe it’s just psychological, but it sure happened to everyone in the mountains.

        You can cold acclimmatise very quickly, simply by having a cold shower first thing in the morning. It’s torturous for the first couple of days, but you soon get used tot it and it you certainly feel warm enough the rest of the day. You can do it slowly to by reducing the temperature of your hot shower a little each day instead though.
        And the added bonuses are, it wakes you up fully and you’re not paying for hot water.

      Yes, it works similarly. I noticed my first year in Taiwan starting in August the winter came and I was still in short sleeves and laughing at the natives with their eskimoish coats on. By the second winter I was one of those wearing a large jacket with a scarf and trying not to freeze.

      Now I’m back in the states. Started riding my bike in the winter and quickly acclimated to the cooler temperatures. Wearing layers and such helped, but I don’t have much problems with it being cooler. My wife has adapted slightly better, but a large part of cold seems to be knowing what to wear.

      When we went back to Taiwan we got a whooping due to the high humidity and heat that we weren’t used to. I’d say it does go both ways, but the cold is easier to handle with just adding more clothes. Part of it is psychological, like my wife “not liking” the cold. This year I think we’ll do even better with winter, but I may be convinced to bump our thermostat up to 67F from last years 65F.

    Hey MMM…I’m wondering if you can EXPAND your temperature tolerance range or simply SHIFT it? I guess maybe it doesn’t matter if the body can SHIFT at a quicker rate than your surroundings can (you mentioned adaptation occurs within a week). If weather is the only factor then its possible the body can adapt to the low-ish frequency temp changes of nature. But is it possible for me to bike 15 miles home in 94 deg weather like I did yesterday and walk into that chilled out pub without needing a jacket? I like to believe I can (as you know, I wear shorts year round) but never found any scientific proof or tried to measure my own stats to see if my tolerance range is actually expanding.

      Until I was relieved of the obligation a couple of weeks ago, I would bike to work in 33C weather, then take a very cold shower and spend the rest of the day working in a room that – due to poor engineering and climate control – was often at 19 to 21 degrees.
      I managed to adapt to the temperature swing.
      The only problems come when you have to repeatedly go through that temperature swing multiple times per hour. At a previous job, another climate control error caused large temperature swings while walking through one set of labs to another. This would cause headaches and other problems for a lot of people.

I do try to last as long as I can before putting on my jacket when I come in and often take a while to remove my jacket and put my hair up when I go out, but I definitely don’t just pick one set of clothing and stick with it.

    “Darwin, the naturalist, says of the inhabitants of Tierra del Fuego, that while his own party, who were well clothed and sitting close to a fire, were far from too warm, these naked savages, who were farther off, were observed, to his great surprise, “to be streaming with perspiration at undergoing such a roasting.” So, we are told, the New Hollander goes naked with impunity, while the European shivers in his clothes. Is it impossible to combine the hardiness of these savages with the intellectualness of the civilized man? According to Liebig, man’s body is a stove, and food the fuel which keeps up the internal combustion in the lungs. In cold weather we eat more, in warm less. “

      It’s true that humidity raises the effective temperature.. but that doesn’t change the fact that you can improve your body’s ability to function in the higher temperatures. That’s the real point of this article – wherever you live, push your comfort limits to make them wider.

      One of the reasons the place I live sounds like a paradise, is because I make a point of talking mostly about good things. A complainy blogger could make this place sound much less fun by focusing on the plant-killing dryness, the short growing season due to freezing nights half of the year, the lack of international culture, oceans, or beaches.. probably many other things too.

      Virginia is better than Colorado in many of those departments, so I’d write about those if I lived there instead. It’s all about finding what’s good in your life and capitalizing on it. But I agree that moving is fun too.

    As a Phoenician who has not yet turned on the central air for the year, I think I am obliged to comment.

    This year we are doing a personal challenge of sorts to see how long we can resist expensive climate controlling. Our electric bill has been hovering at the $60-65 mark, for 350 kwh (that’s 30 in usage but also 30 in fees) and it is ever so much nicer than $200-300.

    Results so far: indoor temp is 95 when it is 105 outside. Night gets cooler but we can only get the house down to ~83 before the sun comes back up for the next day.

    Biggest achievement: We have not died or suffered too much yet, surprisingly. Your body just adapts. It’s awesome, I do light yard work in the middle of the day.

    Prediction: When the monsoons hit and the humidity rises (heat index soars), we will really be thinking hard on the a/c. Might turn on the one wall unit and sleep in that room. It’ll be a hard decision!

    I grew up in Oklahoma without air conditioning. Either your body adjusts or you adjust. We were very used to living without a/c but there were some hot nights with high humidity where my brother and I would sleep in a tent outside for a good portion of the summer. My parents would take our only fan. My sister would mist her sheets so they would be cool when she climbed into bed. I remember being so thankful when there was a cool breeze blowing through the house. I enjoy having a/c now but I don’t keep it nearly as cold as most people I know. And like MMM, I hate walking into a store or restaurant where they have the a/c so low, its frigid.

    Whatever you do, you cannot forget to stay properly hydrated. As an Arizona native and someone more accustom to the heat it’s easy to not realize you still need to be drinking more when you’re exposed to extreme heat.

    Just last week the power on the whole block went out, and I spent time outside getting fresh air and eventually made my way to the local mall. I drank a fair amount (I think somewhere around 140oz), I thought, but ended up suffering from heat stroke. The heat hit a blistering 109 degrees, but I didn’t feel anything at first. When I got home after power was restored it seemed to hit me like a wall. It was the most painful and most terrifying experience of my life.

    I’m not saying don’t do this, because as a native who went back east for college and managed to adjust there as well, this definitely works well. Just be safe, stay hydrated and know your limits.

      As a 30-year AZ dweller myself I’ll add that in really extreme heat like we have here, sometimes plain water isn’t enough. Diluting gatorade (or another sports drink) half-and-half with water can help a lot. Or even just putting a small pinch of salt in your water (not enough to change the taste much). Don’t know if this is equally helpful in humid environments but I would guess that it could be.

      FYI Erica, could be 140 oz of plain water threw off your electrolyte balance. That’s over a gallon of water in what sounds like a short-ish time span. I’m not a doctor, but I’m a trained firefighter/EMT as well as a long-distance runner and that is a lot of water even for me when I’m exerting myself.

In hot developing countries aid agencies pass out measuring spoons to make your own cheap homemade version with water, a big scoop of sugar, and a little scoop of salt. I prefer to make mine with either lime juice or cashew juice concentrate. Google offers lots of recipes online. I live with no climate control except a small space heater for really cold nights (single digits celcius/low 40s F, and a drafty apartment) and 40C/100+F summers, so helping my body adapt seasonally is key.

    Does anyone wake up in a sweat-soaked bed every morning? That’s the most annoying thing about keeping the AC off. Sometimes I will rotate a towel under my body during the night, but it is pretty uncomfortable to roll around in a puddle all night. The same is true if I work on my laptop in 1 place on the couch for too long.

    I thought about getting some sort of hammock or mesh furniture, but haven’t yet.

      That’s not necessarily due to heat, but can be a symptom of a number of diseases, or a side effect of some medicines. Aspirin is a very common one. Do a search on “night sweats” for more info.

      If I find myself sweating at night, I’ll grab a hand towel, get it wet and lay it on my chest, arm or back. Double that up with a small fan (even a desk fan works) and you’ve got a mini swamp cooler right on your skin. You shouldn’t need it to cover too much area, just having a small area cooled seems to do wonder. Obviously if you’re in a fairly humid area, the efficiency can drop drastically. It’s pretty dry in my part of the world.

    Nice! I gradually got used to be comfortable when the inside temperature is between 64 and 80. Could have tried a bigger range but my gf always complains.

    Also, have been driving a car without ever turning on AC this year. All in humid and pretty hot state of Nebraska.

    I know I am definitely used to the heat. I love being outside in the middle of summer during the afternoons while others stay inside staying they can’t bear it.

    One thing that helps is whenever you know you are going to be in a public building, i.e. a doctor’s office or grocery store, for awhile, I always bring an emergency backup long-sleeve shirt or sweater so that I don’t freeze too much in the Summer. Grocery stores, in particular, like to make their interior feel like a frozen arctic ice box (probably to help keep the food cold), while some places just love to jack up the AC.

    Before you bike out from home, always remember to bring that long-sleeve shirt just in case. It is really interesting that MMM has actually figured out the science behind actually adapting your body to temperature.

    Our apartment a/c is set to at 78 degrees. I have energy efficient windows and the energy efficient curtains, but it still isn’t cheap. I keep the a/c off until I feel ‘warm’ at about 83 degrees. Then I turn the a/c on till I feel ‘cooler’ at about 79 degrees and then I turn it off.

    I, unfortunately, am limited because my apartment controls the thermostat and shares the electric bill with the upstairs apartment. We’re about 1800 feet, and I believe its 700 feet up there. The bill is split 60:40 because the upstairs apartment is utilities included by the landlord. So no matter how motivated I am to minimize AC use, the upstairs person is not financially motivated. They do have a windown unit up there, so if they hate my AC management, they can turn it on. It will still be less than the central AC.

    Yes, the two apartments used 2200 kwh in 31 days. I can only imagine what it would be if we ran the AC continuously.

    MMM, how do you plan to categorize the expense of putting up the fence? For example, would this be considered an investment because it may raise the value of your house or would you consider it an expense because its primary function is to make your back yard more fun to hang out in? If I think back on Jacob’s ERE site, he’d call it an expense.

    My wife and I have been doing a lot of home rehab for the past two years on our place and I’ve always considered it an expense rather than investment. We do almost all of the work ourselves, we’ve only had to have an electrician come once.

      It depends. My husband builds fences for a living here in Texas. If the fence is cedar board on board, it tends to raise the property value, so it can be viewed as an investment, at least partly. If its side by side, no benefit other than not *lowering* the property value by having a shabby fence.

    We are fortunate to have a nice “delta breeze” most evenings in Sacramento so we are able to keep the AC off and the windows open.

    Here is the weird thing for me. I don’t mind being hot when exercising or doing yard work but I cannot stand being hot while at work or otherwise “idle at a desk trying to concentrate.” When working from home as a consultant, I would go insane trying to concentrate when the AC was out on a 100 degree day. I would actually drive (Can’t bike, might have got a client call that I need to respond to immediately in a far away land) to a coffee shop just so I could get some work done.

    I would love to move someplace in the Pacific North West but my wife is not too hot (he he) on the idea.

    My California relatives have a swamp cooler. They said it was cheap to run and it really cooled the house.

    http://www.consumerenergycenter.org/home/heating_cooling/evaporative.html

    “In the Arizona desert in the 1920s, people would often sleep outside on screened-in sleeping porches during the summer. On hot nights, bed sheets or blankets soaked in water would be hung inside of the screens. Whirling electric fans would pull the night air through the moist cloth to cool the room.

    That concept, slightly more refined, became the evaporative coolers that to this day provide a low-cost, low-technology alternative to refrigerated air conditioning.

    An evaporative cooler produces effective cooling by combining a natural process – water evaporation – with a simple, reliable air-moving system. Fresh outside air is pulled through moist pads where it is cooled by evaporation and circulated through a house or building by a large blower. As this happens, the temperature of the outside air can be lowered as much as 30 degrees.”

      +1 on swamp cooler. Many older houses in AZ have these. I don’t know why new houses aren’t built with them as frequently anymore. They are very cheap compared to A/C, can be maintained very easily by the homeowner and do a great job cooling. You also have to have at least 1 window cracked a bit for it to work well, meaning you’re getting fresh air exchange in your house. Plus, it puts some moisture into the air that an A/C would just suck out. The only drawback in AZ is July-Aug it gets really humid here during the summer monsoon season and they don’t work as well.

    Someone I used to work with told me about this same heat adaptation. He’d go for a run every day around noon. This is in central Illinois, where, in the summer, we have 100 degree days plus crazy humidity. I asked him how he managed, and he basically described the body’s natural adaptive ability that MMM just did.

    I’m with some of the other posters, in that I find heat pretty easy to adapt to, but I struggle with the cold. I have about a 10 minute walk to the train every day, and on the single-digit and below days, it just never gets any easier. The wind is truly painful when it cuts into what little bare skin I have exposed.

    Anyway, MMM said, “If you carefully and gradually push your comfort boundaries, just as with any form of other exercise or badassity training, you tend to extend those boundaries in a positive way.” I think that’s a general useful strategy for life overall (not just achieving FI). I get the feeling that many people really can’t imagine stepping out of the comfort zone for even a brief amount of time… but it’s really the only way to grow. And I’ve discovered what appears to be a paradox: in some cases, that temporary, self-induced step out of comfort actually becomes enjoyable. In particular, for me, it’s strength training. It’s definitely not comfortable to shoulder a heavy barbell, yet it’s something I enjoy. And when I’m done I feel fantastic.

    I think the idea of regularly and deliberately experiencing some mild discomfort is a fundamental underpinning of Mustachianism. It’s really the exact opposite of hedonistic adaptation.

      That’s true – later I found out that long-sleeved super lightweight white shirt with a collar was ideal. Even as a white dude, my skin is much darker than light fabric in the summer, meaning it absorbs a lot of unnecessary solar heat. Light colored khaki or cargo pants are a good combo for this.

      The thing about the concrete workers is that they were so tough they could ignore things like breathable fabric or light colors. Just their regular black work jeans were fine for them.

          I live on a little island not too far from the equator (off the northern tip of eastern Australia), and when I am going to be outside for long periods (and not having the benefit of natural enhanced sun protection like much of the local population) I use shirts I picked up at a camping/outdoors store that have SPF50 (I think, from memory)They are super lightweight, have vents etc so they are not too hot, despite being long sleeved with collars.

          When it is really hot I put a bamboo or other quick drying singlet on underneath, button the top couple of buttons and have the collar up, so the body of the shirt is loose around me and circulates to evaporate sweat and keep me cool. This means the bits that are prone to sunburn (back of the neck, shoulders, chest) are protected, but I am still cool. I usually top this off with a sombrero style hat of course. This method has worked well for me for outdoor diy projects with lots of sun exposure (e.g., fence painting) as well as long fishing trips in the beautiful torres strait (don’t hate me).

          At the risk of this becoming a v long comment (sorry), I am a reformed whinypants regarding the heat, and I completely concur with MMM that acclimation can occur very quickly. My parents came up to visit recently (from a cooler part of Australia) and were melting, whilst I was running around turning off the a/c because I was too cold. I have only lived up here a couple of months.

    As a hairy man, I find it helpful to trim/shave a lot of my body hair in the summer. This makes being hot and sweaty a lot more comfortable during the acclimatization period.

    To those wondering about cold-weather acclimatization, think about investing in some sort of thin-shelled down coat or jacket. They are incredibly light and incredibly warm. I wear mine around the house when I want to keep the temperature as low as possible. That’s why I prefer the cold; unlike in hot weather, where you can only get so naked, cold weather is easy because you can always put more layers on.

    Totally agree that you can acclimatise – and that you don’t need to tackle it in the extreme way that MMM did. Simply be active outdoors right throughout the year, and it should never be too much shock to the system.

    I’m in a cold (UK) climate, and walk 1.5 miles home from work right through the year, which means low 30s for several months of winter. I would hate that walk if I suddenly had to do it after taking the bus every day, but because I have done it every week as the temperature drops during autumn then I can cope.

    I do agree however that there is only so far you can push your boundaries. In the evening I struggle to stay warm in the house compared to my fiance. Thermal underwear and blankets in the lounge is the order of the day! He just naturally runs warmer than me.

    In hot weather I find life easier though!

    I was wondering why a high of -20 degrees didn’t seem so bad after living in MN for a few years. I’m going to try and take the no a/c challenge this summer. The hardest part is going to be keeping the husband away from the thermostat. He agrees with my mustachian ways but has some trouble with the follow through.

    I think I’m acclimated to the heat more than him since I’m from the South and he’s not. I play roller derby and skate outside during the summer a lot which builds up my tolerance as well.

    When it was in the 90s the past few weeks we used frozen 2 liters in front of a fan to create inexpensive a/c. A medium tabletop fan only uses about $10 worth of electricity a month (measured our with a kill-a-watt device). We keep several 2 liters in our freezer that we swap out. Keeping your freezer full actually uses less energy. I’d like to think we break even but I haven’t measure that yet.

    We also signed up for “Savers Switch” with Xcel energy. It’s this device that attaches to your central a/c unit which turns the a/c on and off every 20 minutes for just a few hot days during the summer. We get a 15% discount every month June-September every year for participating. If we use no a/c, then we still receive the discount! I’m liking the idea of saving money by pairing little to no a/c usage and the 15% discount!

    Great point. There are also a lot of efficient ways to retrofit your house to either use less energy to maintain temperature in a given range, or to have a more comfortable home without AC. I installed a radiant barrier in my attic last year (ok, so I actually paid someone else to do the work, which was admittedly non-mustachian of me, but it was before I discovered this blog). I haven’t run my ac all year (I live in north Carolina) — it’s 81 degrees in my house, I have the ceiling fan on low, and I’m feeling fine. My electric bill is down 30-50% since the installation. Tomorrow, I’m picking up someone’s discarded concrete footers to add some thermal mass to my house.

We’re not wussypants over here – we bike to work and back every day and we’re fine. But apparently our house can’t handle the heat. Any recommendations?

    Another method of reducing heating and cooling costs is heat/cool only a small part of your home.

These feel pretty tolerable. So does walking. But if I try doing other exercise outside or in an uncooled venue, the heat catches up to me very quickly, faster than the other people around me doing the same things. I’m not sure whether biking is just a poor way to be exposed to heat, or if there is something else going on.

    It also goes back to keeping yourself in good physical condition. People who are lean and a healthy adapt a lot quicker to the weather than the overweight and in poor health. Overweight people “love” the heat….

    Spent last summer bicycling from Budapest, Hungary to Prague, Czech Republic. It gets scorching hot in continental central/eastern Europe, and we had 960km to cover.

    – First day: we arrived at noon in Budapest, fled into a shopping mall to escape the heat and barely made it out of the city and onto a camping.
    – Second day: we started early, stopped at a sleepy village along the Danube river, raided a mom’s and pop’s for food and unrolled the ultralight hammocks under a couple of massive trees to watch the town ferry go back and forth for a couple of hours. Gorgeous, but not doing much.
    – Third day: everything became business as usual. Cycling from 9am through 6pm in the heat on bicycles packed with camping gear and wildly varying elevation levels? Ninguna problema, hombre.

    You mentioned the idea of drawing in outside air at night, to take advantage of cooling. That works nicely if you consider your HVAC system primarily a means of regulating temperature.

    In our household, the HVAC system has as its primary function the filtering of air and removal of allergens, which everyone in our family has severe trouble with. Temperature remains a secondary concern. The HVAC system exists to keep the outside *outside*, and separated from *inside* by several layers of filtering. As a result, none of us need to take our allergy medications when staying inside, only when venturing outside during the ~12-month allergy season.

    Given that, we try to let in a minimum amount of outside air, at night or any other time. The temperature difference might improve efficiency, but at too high a cost in comfort. We’re well aware that we burn a significant amount of money doing this, and we consider it worth every last penny.

    Writing that out explicitly actually made me think of it in a way that I hadn’t previously, which makes me feel even better about it: I can easily measure the additional amount we’d spend on allergy medications if we had to take them every day rather than every time we go out. A quick estimate puts the additional cost at approximately $167/month just for *me*, not counting other members of the family. Averaging that over the course of the year, that would cover the entire electricity bill by itself with room to spare (not just the AC costs, and certainly not just the additional AC costs incurred by not making use of cool outdoor air at night).

      Anonymous, while your comments are thoughtful, I think you might have a slight case of “complainypants” disease!

      If you’re allergic to the place you live, maybe it’s time to figure out where you can live that your body doesn’t fight constantly? Depending on man-made structures to protect yourself from nature should be a last resort rather than a preferred way of life (unusual chronic illnesses aside, of course). You might even find, like I have, that allergies disappear with health improvements (I used to be destroyed by summer allergies in my early 20s, and now haven’t had a plant made me sneeze for many years – no filters, no medicine!).

        (First, a correction: my quick estimate of allergy medication expenses if required daily actually overstates them by a factor of two; I misremembered the number of doses in one prescription. That changes the math enough to suggest that I should actually do the math to check my hypothesis.)

        I have a sufficiently broad spectrum of nature-based allergies that unless I want to live in a place mostly devoid of plant life, I’d still have problems anywhere I went; this area actually provides a significant improvement in that category compared to other areas of the country. And I love this area too much to trade it away for lower allergy-management expenses, even ignoring the advantages of this area from a career and cost-of-living point of view.

        We’ve already selected a region of the country with a fairly optimal balance of relatively low allergy problems (by comparison to other places we’ve lived) and quality of the area in the hundred other ways that we love.

        Look at it this way: you’ve chosen to spend extra on your home, as something you highly value. I’ve chosen to spend extra on my home in a slightly different way.

        I already have specific actions and goals to improve my overall health, and if that leads to a significant decrease my allergies, wonderful. If not, my allergy medications and air filtration will continue to fall firmly in “cold dead hands” territory, which in practice means that if I need to cut that amount from my spending I’ll find somewhere else to cut it.

        Also, I want to point out that I never allow allergies to provide an excuse for not doing things, least of all going out into the world; that would indeed make me a complainypants. I will not become a bubble-person; however, I enjoy spending time in my home, and thus I’ve optimized my home to support me more efficiently. “Put on slippers rather than carpeting the world” should not stop you from carpeting your home. Figuratively speaking; wood floors all the way. :)

        I only brought this up at all because your article assumed only a single use for HVAC systems, namely temperature control; I wanted to suggest an additional use that you might not have considered. Please don’t take that to imply that I allow allergies to become an excuse for me, rather than a simple obstacle that I have found many ways to overcome.

          You might want to try a Paleo diet. I suffered for years from allergies (no medication or conventional therapy or alternative therapy would touch it) but I’ve experienced a lot of improvement in my seasonal allergies for about a year now since converting to a Paleo diet.

    Reading this here in the UK in London where it hasn’t stopped raining for six weeks and the temperature has barely got above 20 (erm, 70 fahrenheit?) this post is much more provocative than the financial ones… ;)

    I can tell you what in contrast the world’s best natural heating system is… an air flight to Spain! ;)

    Nice project.

    What the writer describes as “badassity” is otherwise known as outdoor work.

    Grandparents been there, did that.

    The article points are valid; if you’re in moderately good health then don’t let yourself become a prisoner of 24 hour climate control.

    And if you haven’t tried it, the bike idea is a real win. Even at a modest pace, the bike breeze effect cools you off, and bc you are outdoors and not stuck to a chair sweating isn’t unpleasant. Just wear stuff that feels good when you sweat, a headband to keep it out of your eyes, and a hat/helmet of some sort.

    Recently discovered the blog, and I love it. Prior to setting foot on the path to mustachianism, I bought a house 1700 ft.² brick, nice but radiates heat at night and I live in upstate New York so the humidity is almost like the sweltering jungle. That being said, the only room in which I have an air conditioner is my bedroom and I only turn it on to sleep. I can live with the heat during the day but it is almost impossible (for me) to sleep with the heat at night even with open windows and fans. I also went to Austin, Texas (holy crap, what an awesome town) this June and found myself gradually getting used to the heat as well but I think the big component there was a lack of humidity. If you live in a climate where there’s not a lot of humidity I think it’s a little easier to acclimatize yourself then it is with the crushing humidity in New York (and yes, I am being a little complainypants here, but hey, I’m a junior Mustachian, it doesn’t happen overnight, ha.)

    I’m also discovered this blog and would love to bad-ass my ways some more. I live in a 1100sqft 1.5 story wartime home in southern Ontario. Now I’m not going to convince the wife to go without AC in the dead of our humid-ass summers, however I use our poor-man’s AC when ever I can. I use the ‘stack effect’ of the house, where there’s a temperature gradient between the basement and upper level, I turn on the upstairs bathroom fan to exhaust the hot air while turning on the furnace blower to circulate the cool air from the basement.

    As for vehicle A/C, I never much cared for it and use it at little as possible. The one reader described been blown cool dry air mixed with the radiant heat from the glass was their less-preferred choice of discomfort. However I’m vetoed by the family on this one. I have some work to do.

    At the risk of copying other statements, YES! I get so sick of people in my area who complain about cold winters and wonder how I can walk to work even in the middle of winter. I have two things I say: one is that you get used to it, the other is that I actually dress for the conditions! So many people here expect to dress like they would at any other time of year with maybe some overclothes (hat, scarf, gloves, coat) and then complain that they’re cold. (I live in interior Alaska.) When someone complains about the cold I either point out that they could move, or that they could throw on some long underwear and stop whining.
    People lived here long before modern conveniences. I consider myself damn lucky that I get to walk from one heated building to another!

    I know I’m late to the conversation here, but I love the concept of heat acclimation. I currently live in Arkansas and the summers are VERY hot and humid. I work from home and leave the A/C off all day. If I get uncomfortable, I just put a small fan near me. I don’t have a car, so I walk and bike everywhere. I purposely try to go running during the hottest part of the day for that acclimation. There is another benefit to dealing with the heat… appetite control! During these hot days, I find that I eat waaaay less and I crave mostly raw fruits and veggies.
