- arisAlexis 4y agothis doesn't make much sense. It would mean people near the equator sleep worse or that someone used to the North moving to California will experience worse sleep. Sounds like p-hacking random study.
- jawarner 4y agoYou ever toss and turn at night because it’s just too hot to sleep? Someone moving from the North to California would likely experience that. I know I did when I moved to Texas and my air conditioning unit broke down. The authors say there is adaptation to the local climate so someone living near the equator might still get good sleep. The data is based on weather, and it checks out; it’s hard to sleep on a hot summer night.
- xwdv 4y agoSo the takeaway is just adapt.
- arisAlexis 4y agoIt'd hard to sleep for you not Africans. 1C difference can't make such a difference since we can adapt. I am all for climate change but the title of the study sounds meh.
- Qem 4y agoI spent the first half of my life living 7 degrees south of the equator, in a city where temperatures in the hot season routinely go near 40o Celsius. I can tell first hand, it wrecks your sleep. Sleeping in a mattress is unbearable, even under low humidity and with a fan, your underside gets too hot, and the entire night is spent flipping in the bed. The only effective adaptation available to poor people, without AC, was to sleep in hammocks as a default. It avoids getting your underside too hot.
- voxl 4y agoIt could be as simple as the relative change is one people aren't yet used to. If you grow up in 100 degree weather your whole life you get used to it. Probably there is some delta of time where we would adapt to any change in temp, but if the temp itself is constantly increasing then maybe our adaptation can't keep up as well
- Comevius 4y agoThere are plenty who thinks that people who can't buy an air conditioner are lesser and don't deserve one. Bootstraps and all. I like to look at the bigger picture, this will cause further instability in the world, which is bad for all of us. Besides the consumption of those who can afford an air conditioner drives climate change. You may be handing over the money in the shop, but it's the entire planet that subsidizes your purchase power, which is not cool, literally not cool.
- giantg2 4y ago"this will cause further instability in the world," What will? How?
- Comevius 4y agoClimate change, what else would we be talking about?
- giantg2 4y agoI don't see lack of air-conditioning causing instability. Other aspects of global warming, sure.
- Comevius 4y agoMost people live in houses with poor insulation and ventilation, because they either don't used to live in a hot climate or have air-conditioning. We don't build smarter because air-conditioning is cheaper, but a lot of people can't afford neither, and they are becoming necessary to have.
- scrollaway 4y agoAir conditioners nowadays can and should be bought as reversible heat pumps. It adds nothing to the purchase price and it replaces gas heating as a much more efficient way to heat a building. We should be installing heat pumps everywhere. Power consumption may go up in summer but would go way down in winter as efficiency is greatly increased. Unless your point is that poor people don’t deserve heating any more than they deserve cooling…
- dsq 4y agoI definitely sleep less well in the hot, humid, summer than in winter. When it's cold you can add layers. When it's hot you reach a limit of zero layers of clothing/coverings and then have to move the heat and humidity elsewhere artificially via A/C. I also think (this is my subjective opinion, I have no proof) that cold reduces swelling and inflammation, thus making for easier breathing during sleep.
- FooBarWidget 4y agoJust having a regular fan helps a lot. Very little energy usage, very cheap. I bought a new fan a few weeks ago, one that is nearly soundless in its lowest setting. Even the slight breeze made by the lowest setting already makes a huge difference compared to stale hot air. It also uses an order of magnitude less energy than an A/C, and costs an order of magnitude less to purchase+install (100 EUR vs 3000 EUR).
- dsq 4y agoOh, absolutely. I use a fan from April through May. Come summer with 35-40 degrees and 80-90 percent humidity, as is the case for six to eight months of the year in many places, no fan will help, only true-blue A/C. Moving air also helps against mosquitoes, I have read!
- FooBarWidget 4y agoI have also noticed that whenever I turn on a fan, there's less chance that I end up with a mosquito bite next morning.
- dotancohen 4y agoMosquitoes identify us by our CO2 emissions. So getting rid of the CO2 bubble coming out of our noses does a good job of masking us from the mosquitoes.
- samatman 4y agoDo you have a heat pump for heating? If you do, you get A/C for 'free', and if you don't, you're wasting so much energy in the winter that you can never make up for it by 'making do' with a fan rather than proper air conditioning. Signed, some guy who was in Belgium for the heat wave in 2018 and thinks Europeans should just suck it up and put in heat pumps. Sweltering in the summer and burning gas directly in the winter isn't virtuous.
- jawarner 4y agoThe gist: On hotter nights people get less sleep, this being especially the case for people who are poor (limited access to AC?) and who already live in hot climates (100->110 deg is more noticeable than 70->80). It’s nice data. They gave sleep tracking watches to 47,000 subjects for a few years, and this is what came out of it. Their climate change angle is suspect. It probably helps publish to be relevant to a real-world problem. But their final paragraph undermines the projections they try to make: people adapt to the long-term weather patterns, and they’ll likely partially adapt to climate change occurring over the course of 50 years. Of course it’s still relevant from a health equity standpoint to consider.
- hammock 4y agoI'm inclined to agree with you and it makes me wonder, why should global warming be a more favored subject than health equity?
- masklinn 4y ago> why should global warming be a more favored subject than health equity? Because global warming is a large driver of health inequity and a billion other issues as well?
- jawarner 4y agoTheir angle was health equity in the context of global warming and how it impacts different populations to various degrees. That’s a common trend in global warming related issues. Their argument is fair enough. My issue with the paper was specifically with the projections they made, which extrapolated the effect on sleep caused by the weather all the way to effects on a 50-year interval caused by warming trends. But by the authors own admission people can physiologically and technologically adapt — at least partially — over long enough time periods. To be frank I think it’s a way to make a compelling headline. They have the statistical tools they have, it would be incredibly hard to account for long-term adaptation, and so they come up with some statistical estimate of the long-term trend. I see why they did it, but from a readers perspective it’s okay to be critical.

- joemaller1 4y agoCan we also talk about light pollution? Birds aren’t sleeping either.
- beebeepka 4y agoTrue. There are some parks with all kinds of exotic birds for human attraction. I get every time seeing all the projects lighting up the ponds and trees. Absolute madness. And sound pollution, too. Fucking vehicles, man. I live in a busy city and in my estimates night traffic is at least 90% pleasure. How do I know? Only idiots force their engines during the day, and at night I mostly hear idiots Inconsiderate fucks.
- gwern 4y ago> The elderly, women, and residents of lower-income countries are impacted most If small increases in global temperature can impact sleep enough to care about, then that is a much stronger additional argument for economic growth( to make AC, which can reduce night temperatures by a lot, affordable and universal) than it is for trading growth for some small avoidance of further temp growth. The latter is how I expect most people will read this result...
- BurningFrog 4y agoThe "elderly, women, and residents of lower-income countries" is about 80% of humanity.
- moffkalast 4y agoAlso coincidentally, the exact people the ruling elite gives zero fucks about.
- dotancohen 4y agoWhat about all the non-human primates/mammals/vertebrates/animals affected?
- gumby 4y agoAC heats up the planet though (just think of the thermodynamics: not only to you pull out the heat and expel it outdoors, but that takes energy, which ends up as heat exhaust as well). People need cool air, no question, but it's not a free lunch. We need to cool the climate as well. (BTW I do believe everybody should have access to as much energy as the OECD countries use per capita. Sadly even this is controversial)
- herf 4y agoThey've identified several correlates due to weather (cloud cover, rain, wind, day length), but then I can't find where they correct for these in talking about effect sizes. All of these effects then "add up" to make the nearly 10-minute variation in sleep duration. Also, sleep isn't only about duration - most sleep scientists would want to know about sleep efficiency too. This is "time asleep / time in bed". If you wake up more when it's cold, then there is a reason for shorter sleep when it's warm. Similarly, you'd ideally correct for air conditioning and factors like this on an individual level, but they don't seem to have this data. Activity before bed, and the light that gets into your bedroom in the morning are certainly correlated with heat. It's important to investigate how these variables interact.
- an9n 4y agoI suppose we could do something crazy like, I don't know, moving somewhere cooler?
- GuB-42 4y agoAnd move the whole city with you? Otherwise you will find yourself in the middle of nowhere with not much to do and not much to support you. That's actually a big problem with global warming, maybe the biggest problem. Raising waters? Just move coastal cities on higher grounds. Some countries will actually benefit from global warming, I think that's the case for Canada, just move there. But that's not how it works, you can't move around millions of people and hundreds of years worth of infrastructure just like that.
- marcosdumay 4y agoWell, while their title alone leads to a "no shit, Sherlock?" response, because it's quite clear that it's hard to sleep in abnormally hot days (but there isn't anything there about the impact of global warming that it wants to push), that is really a data-mining study that found a correlation inside a huge amount of possible variables. That means the study itself is a solid base for further examination, but meaningless for any real world conclusion.
- sandworm101 4y agoIdea: could this be an evolved trait? Could it be that sleeping less during hot weather was an evolutionary advantage? Maybe spending more time asleep during the winter, presumably when food/resources are scarce, lowered energy needs and so increased survivability. In hot climates, predators are more active at night. Maybe our aversion to sleeping during hot nights evolved from a need to stay awake when the lions/tigers/bears were out looking to eat us? That could be why I find it easier to sleep out in the sun in the middle of a summer day (siesta) than I do at the same temperature during the night.
- LinuxBender 4y agoThis comment won't do well right now but I suspect in the future we may come back to this idea. I believe more work needs to go into automation of forming/welding frames for underground homes as the temperature is rather constant under ground. 3D printed/molded? Some locations will need specially built units that can handle moisture. I have probably binge-watched too many mining/tunneling videos but I could see this technology becoming affordable to the consumer through technological optimizations, maybe? Anyway moving the home under ground could provide additional room above ground for a garden or parking spots. Underground homes would also be tornado resistant. Another advantage is energy efficiency or moving towards being carbon neutral. There are concrete / shotcrete companies making carbon absorbing material now. I am thinking of the real world example of Coober Pedy, AU [1] They have subterranea hotels, mines, homes, recreation facilities and more. If I ever went to AU that would be my first stop. Anecdotally my home is partially earth bermed and even on hot days hot being around 101F it is cool in my home and I do not even own a HVAC unit. One of the many reasons I moved was due to heat and sleep issues. [1] - https://en.wikipedia.org/wiki/Coober_Pedy https://en.wikipedia.org/wiki/Coober_Pedy
- DoreenMichele 4y agoPartially earth beamed falls under passive solar design. That's actually got real potential for helping us meaningfully mitigate these issues.
- ekianjo 4y ago> Underground homes would also be tornado resistant earthquakes are another problem though
- LinuxBender 4y agoTrue, though it appears to be the same liquefaction risk that above homes are subject to. [1] Geological surveys would be more important and I suspect compensatory insurance would be harder to acquire. That said if the automation brought the cost of these units down far enough then perhaps only liability insurance would be required as the unit could potentially be recycled if it were designed with that in mind. One could rent an excavator at $150 to $400/hr depending on size required to remove the top soil. If the rooms were modular then the excavator could lift or maybe even drag out the damaged room to be swapped out. If not modular then a crane would be required. There are bomb shelter companies designing underground facilities that can withstand earth movement and allow the occupants to escape harm. I won't link to those companies as I feel they are over-priced and this could be done much more efficiently with advancements in automation and recycled materials. For small facilities like homes I believe this is a mostly solved problem. A harder problem in my opinion would be a commercial mine due to the size/scale. Steel I-Beams and steel plates throughout a lengthy/deep mine would be very expensive as opposed to the wire mesh and 8' anchor bolts and shotcrete used today. A modular home would be far less likely to cross liquefaction and plate fault boundaries.

- jokoon 4y agoIt's hot this week in france and I had very poor sleep. I have been thinking to move into the mountain, in a city where the weather is much cooler in the summer.
- racl101 4y agoAs a hot sleeper I can attest. I'm the guy who will crack a window open in -15 degree (celsius) (5 degree F) and think: perfect.
- throwrqX 4y agoBy the sounds of the comments here I must be the only person who can sleep in 33c (91.4f) degrees and not be bothered at all.
