People from the "hotter" regions, how do you deal with the heat?
I am from Eastern Europe and this is the hottest summer on my memory. For at least 3 consecutive years the heat is breaking all records.
This stuff is unbearable, I can’t even play video games on my laptop, because it warms up very fast and the keyboard becomes uncomfortable for me to use.
So, could you please share any useful tips on how do you survive the summer?
Ceiling fans should be set to warm weather mode (there should be a switch on the base which changes the direction of spin), you want them to pull hot air up (so the lower edge is the leading side) push cool air down, had it backwards
Cotton/baggy clothes: cotton loses all insulation properties when wet so its nice on a hot day, baggy clothes are generally more breathable
Self-misters are fine, but do not use humidifiers, lower humidity = faster sweat evaporation = cooler you
Drinks w/ ice and/or icecream: cold stuff inside your body will cool you down
Avoid the outside at 1-2pm: this is usually the hottest part of the day
For your laptop: buy a desk fan and point it right at your laptop, has the bonus of cooling you down too
Ceiling fan is opposite. You're cooled by the air going over your body. Typically (in US, at least) that means counter clockwise in summer and clockwise low speed in winter.
Also as to clothes linen layers are fantastic in heat if available.
air will be blown over your body either way, all you're changing is the direction the air is coming from. blowing from the ceiling means blowing hotter risen air
While viscose dries faster than cotton, cotton is a breathable fabric and lets you sweat, which cools you down. - Indian here, so have some experience living with hot weather.
Loose, long-sleeved cotton clothes will prevent sunburn + cool you down.
Yeah, ceiling fans are a very rare thing in Eastern Europe. I haven’t ever seen one with my own eyes and I have been to all kinds of places in my country
Wear loose cotton clothes (long-sleeved if stepping out in the hot sun)
Keep yourself hydrated.
Avoid soft/ aerated drinks/ soda & coffee as they'll dehydrate you. Stick to cool water, ice chips, fresh lemonade made with water, fresh fruit juices, melons, spinach-cucumber-onion-tomato salads, yoghurt,
Eat light.
Stick to well-ventilated rooms with good air-circulation (fans help)
Cold water showers to cool down
Sweating is good. It'll cool you down. This is also why Indians eat spicy food and drink hot tea even in hottest summer. Get sweaty then take a quick cold-water rinse.
If you have to step outside in the hot sun, umbrella, hats, caps etc are your friends.
Wet towel on the back of the neck for a quick cool down.
ETA: When it gets so hot that we lose our appetite, then our go-to meal is to mix up cooled cooked rice with unsweetened yoghurt and a pinch of salt. its variously called yoghurt rice/ curd rice/ thayir saadam / dahi bhaath / dahi chaawal . This is an easy to make & easy to diges meal that is guaranteed to cool a person down.
thayir = dahi = curd = yoghurt
saada = bhaath = chaawal = cooked rice
I’d make one exception: cotton wants to hold water. Evaporative cooling needs water to evaporate. There are synthetic materials that will hold much less water, so they’ll weigh less from sweat and evaporate more quickly, providing a tiny bit more cooling. Plus many have protection from the sun reducing the amount of sunscreen that has to be worn.
There are a line of shirts known as “fishing shirts” that are made to be big, and they have vents to encourage air to circulate inside them. They work great.
I’m in the US and it was 40C (104F) yesterday, which is normal for my area. I spent the whole day either indoors or in the neighborhood pool, and it was perfectly comfortable.
I mean, I bought my window ac at least 10 years ago, the only upkeep is cleaning the filter. no issues. I bought a house with an AC from the 70s or 80s in the wall, also nothing but washing the filters. Sure I'm using electricity, but I wouldn't call that upkeep.
But it’s either this or hospital. Human body can’t cool down in very hot and high humidity environments, for example 40 degrees and 90% humidity. My mother was sent to hospital due to heat stroke, AC is life-saving. It would be better if there were better ways.
Right. I don’t think individuals can or should do much beyond setting their AC at reasonable levels.
The responsibility is on governments to heavily invest in renewables so that we don’t continue on our current trajectory. If governments don’t act, the earth will inevitably force some sort of reduction in energy usage and it’ll be far less comfortable than higher taxes.
Exactly. The issue is with the source of electricity, not with the AC itself. Not to mention that leading by example is nice, but it's not always the best course of action. An individual avoiding AC is a drop in the water, and not going to save the planet, while suffering immensely. Hell, even if every single individual stopped using AC at home (which isn't even close to reality), that wouldn't have a significant effect, compared to what corporations, factories, etc. are doing.
The price of electricity in my country (the UK) has gone stupid high right now. We don’t have AC in our homes normally in the country. But I bought a 2nd hand portable unit about 7 years ago when my first son was born cos I was afraid of him gettin too hot at night. I have a 2nd son now and we have had some record high temps last month and o could only afford yo keep this AC unit on for a like 2 to 3 hours at night time in just his room and only on the hottest days. Anymore than that and we woild struggle to pay the energy bill that follows.
It’s not maintenance cost that’s the issue. It’s energy cost.
I can get about six hours of free heating during the day from the sun over winter in Australia, using solar and a split system. Only if the sun is unobscured though.
Summer is better of course, due to the longer daylight.
Indeed, many places are 40 and 90% within a day, but not simultaneously. You can see in your image how the peak humidity was at 00:00 and the peak temp at 14:00.

I agree. I have lived in hot, humid places without air conditioning. The only solution is to find cool places (in the shade, in a cellar), stay wet, drink lots of water, and avoid physical exertion until the sun goes down.
I am spoiled now. I live in a region with cheap, low-carbon electricity (almost entirely from hydro, nuclear, and wind) and modern infrastructure, so air conditioning is standard practice. I wish the whole world could have the same.
Most of the world does not have central heat and central air.
In many areas, pools can be difficult due to a number of economic, social, and other factors.
Additionally, running AC constantly also puts more heat outside and, depending upon your power source, increases emissions further contributing to global climate issues just making things worse.
You want to get some nice blackout thermal curtains for any windows facing south. You might actually need 2 sets of curtains to fully block the sun. I’ve noticed a big difference this year since I added a 2nd thermal curtain on top of the 1 I had. Unfortunately that only helps so much and as long as it’s unbearably hot outside you’re going to see the heat increase inside as the day goes on. At night open all of your windows and run fans to get as much airflow as possible while it’s cooler outside. In the morning close your windows the minute the outside temperature is the same as the inside temperature. As long as it’s cooler outside, the windows should be open.
Get a desktop. Despite what people are going to tell you, laptops are not an optimal choice for gaming. It usually always comes down to the fact that those little tiny cases are not efficient at removing heat.
Over heating and under performing is the typical story for gaming laptops.
The comment is kinda bold but I can’t blame you since you don’t know anything about me and stuff
I have a desktop it’s specs are on par with laptop’s ones. I don’t use desktop nowaday because it’s a less power efficient option whilst I can accomplish all tasks on my laptop. No, I didn’t buy a “gaming” laptop, lmao, they’re all a joke. I only mentioned videogames since I play them occasionally and it was a good example of how bad the heat was at the time
When the weather hits 40⁰ around here I might head to the cinema. They’re usually really well temperature controlled, dark and allows you to get out of the sun when it’s at its height. Nights when it doesn’t cool down are harder.
Houses are built differently in hot areas. Very few windows facing south. Shutters on all windows. All windows deeply recessed. Channel the wind, ie have a deep through channel that spans across the house so any pressure differential causes air to exchange. Tiled floors. No/low insulation.
In Northern Europe, we live in sweat boxes designed for letting in maximum light and keeping heat inside the house.
The one thing I don’t see mentioned enough for keeping your apartment cool is to close all windows and draw all curtains during the day and open them when the temperature outside is lower than that inside (normally ~an hour after sunset).
Heat reflects off all surface, so it’s not just about keeping light out.
Blinds on the outside of your windows help significantly too.
I wish the temperature outside dropped below my house temp. If I run AC at even a money saving 83 degrees inside, the exterior doesn’t drop below that until around 6am.
Totally. Blows my mind that people can’t seem to understand that if it’s hotter outside than inside, the inside won’t get any cooler by opening windows.
Last summer in London (42 C!!) we became a box of shadows during the day. Keep the cool inside.
Use fans. Air blowing on you will make you feel cooler. If you don’t have air conditioning some houses can benefit from one fan blowing inwards from the cool/shady side of the house and one fan blowing outwards on the hot/sunny side of the house.
Try to do outdoor things early in the morning or late in the evening. If you need to be outdoors during the hottest parts of the day stay in the shade, wear sunscreen, move more slowly, drink plenty of water.
I need AC for about 6 months out of the year (used to be three, maybe three and half) here in the east/south US. The humidity is so bad it makes 90F seem like 110F and even the shade won’t cool you down and it drops very little when the sun goes down.
I’m replying because my electrical panel is being replaced right now and I have no power (the router is on a batt backup)…it heated up in here and I’m able to psychologically deal with it for now…if the installation goes south and I’ll be without power for more than a few hours I’ll take the cat and head to my sister’s place :)
Avoid being out in the midday sun. If you do, try to walk in the shade as much as possible.
If your windows have external shades close them down when the sun is hitting that side of the house/appartment so that the heating up of objects from the sunlight happens outside not inside.
Wear shorts/skirts and loose clothes of thin textites that don’t retain much heat (such as cotton).
If you’re going to be out for long periods, bring water, ideally cold water.
Sure, if you have AC or, even better, a swiming pool, it’s a lot easier to keep cool, but these suggestions will work even for those who can’t afford those things.
I recommend getting a metal water bottle and carrying that around when you’re sightseeing or any activity that keeps you outside in the sun for long.
Also I personally never noticed any extra sweating when drinking cold water versus ambient temperature water, and I live in Portugal were we regularly get 40C or more in August. Generally, if it’s hot enough you’ll sweat more simply from the heat (as sweating is a natural cooling mechanism) even if all you drink is plain tap water. Sure, if you don’t drink water you’ll sweat less, as you’re getting dehydrated so the body will cut down on that.
Were did you learn that specific piece of information about cold water making people sweat more?
