I grew up without AC in Florida.
Sit in the shade with a fan, be still. If in the shade and a breeze, and not moving around, a pretty high temperature is comfortable.
Go to places with cold AC or to cold springs to get cold, it will last awhile after you leave.
If it gets cool at night, open your window at night to let in the cold air, close it in the morning to keep that air in for the morning. But once it heats up inside, you are better off with ventilation - open windows on both sides of the house and run fans, to move air throughout the house.
If it’s dry where you are (it doesn’t work here) get wet and let evaporation cool you. Even here you can get wet and stand naked in front of a fan you will get cold.
STAY HYDRATED.
Unfortunately I got used to it. I say unfortunately because lukewarm weather (even something like 22°C) feels extremely cold to me as a result.
Block out the heat and sun during the day. Have everything open during the night, with a tactical fan placed wherever it helps the most.
But this only really helps the first few days. After that it’s down to accepting the situation and being so tired that you fall asleep anyway.
tuen on the fans, close shutters during the day, drink water
If you have a freezer and a fan, freeze a bunch of water bottles and then put them right behind your fan blades for a cheap AC-like chilly breeze. If you have enough bottles, you can cycle through them and refreeze as they thaw out.
I’m no thermodynamics expert, but wouldn’t this make your house warmer overall, unless the freezer is outside or in a garage/shed?
It will make the air behind your fridge warmer in exchange for making the air around your body cooler. There’s usually not great airflow behind the fridge so it won’t affect the rest of your house much.
If you’ve got an open kitchen or something you can still freeze the bottles at night and use them during the day.
You’re right which is why our freezer is out in the garage rather than in the house.
It will
Put them in a huge bowl of cold water to stretch the effectiveness. I did exactly this during an unbearable summer and it worked well. As to the comment about heating a room, you’re providing cool air on yourself. Worked well enough for me.
Wish I knew this a few months ago
Another thing you can do is buy an ice vest - a vest with waterproof pockets for ice packs. They usually come with a load of extra ice packs so you can freeze and cycle through them. They’re great if you have to go outdoors for something.
AC is expensive but the freezer is already on so I’ve been rather creative with its use haha.
Doggo also enjoys a rubber bone thing that I fill with water and freeze so he can chew and stay cool. Also love freezing ice cubes full of berries and stuff too.
Thanks, I’d forgotten about this one. Our AC will be out for a few days. I’ve already started loading water bottles into the freezer.
Run cold water over your wrists when you’re starting to get hot.
Or any area of your body where there’s a lot of blood vessels near the surface of your skin.
I like standing in a cool shower and letting the cool water run over the front and back of my neck.
And dab some cold water behind your ears.
Most important here is the dabbing.
All the coolest people dab, often and without irony.
When I worked in a restaurant kitchen, we used to soak rags with water and freeze them in the walk in freezer, then once it’s nice and frozen we’d wear the rag around our necks.
There’s large blood vessels in the neck feeding your brain, so if you’re able to cool down the blood there, it’ll spread to the whole body surprisingly fast.
I actually managed to get cold in hot humid july summer in the kitchen with that method.
I was previously convinced that taking cold showers was my only saving grace during hot summers, but this year I got the advice to try to take a warm shower a short while before bed, and I’m surprised to say that it has helped. This is for high 20s though so YMMV for sure.
Other things that help:
- Open windows when outdoor temperature is lower than indoor temperature, and try to get a cross breeze going if possible
- Keep light out of the house by closing blinds during the day
- Wear linen clothing and use linen bedding, this material works better for warm conditions
- Fans help reduce perceived temperature by several degrees
If you have cool nights, setup fans up at night to bring the house down to a lower temperature. Close everything up in the morning when the outside temp starts rising above your inside temp. If your place is insulated reasonably and there’s no excessive sun from windows, it will stay cool for the day.
Protip: Setup the fans in all rooms on one side of a chokepoint in your house/apartment (stairwell/hallway) to exhaust, to encourage airflow. Open up all the windows on the other side for intake. It’ll also help reduce pockets of hot air left over from the day before.
Pro tip: Point the fan so that it blows outside and DO NOT put it directly on the window or right next to it. Instead, move it ~50cm away from the window to take advantage of Bernoulli’s principle (push the air out more efficiently by pulling the air surrounding the fan).
You can cool down the room even if the door is closed. You are lowering the pressure inside your room so the outside air is forced to rush in. If you place the fan like I explained, and point it at the lower part of your window and you put your hand next to the upper part of the window, you will feel the cold air coming in.
Cool shower! Put water in your tub with a fan nearby.
I’ve never gotten this to work very well. Though I didn’t do it with a fan. Any tips?
Get in tub; get out; lie in front of the fan. It won’t cool your house, but it will keep you from dying of heat stroke.
Ah, I thought you were using the shower as a way to cool down the air for your house. This makes way more sense.
I’m sorry, but are you serious?
Any tips other than the fan…
You could try an ice dildo. I hear that a 6 incher tends to last about an hour…
Live in a dry climate. The evaporating water will cool the house. Doesn’t work if the air is already wet
I practice this same thermal battery idea as well with an extra tip of having a couple of fans on timers (sun up to sun down) that sit on the floor and blow the cold air up. It makes a significant difference, especially if you can sit a fan where the cold air from the AC falls to the ground.
Around here, Portugal, were every Summer the temperature exceeds 40 C for at least some days in August, we have outside rollup shades on every window, so one of the tricks is to keep the shades down and and the windows closed during the hottest and sunniest parts of the day, at the very least the afternoon.
Then at night you open the windows and let the cooler night air in (even better if you do it early morning, around sunrise, which is the coolest time of the day).
Note that this doesn’t work well with curtains or internal shades, because with those any conversion of light into heat when the light heats the shades/curtains (as they’re not mirrors and don’t reflect all light back) happens inside the house and thus that heat gets trapped indoors.
I have internal curtains and blinds and this actually still works well, at least better than keeping them open. Maybe it would work better with externals but this is still worth doing if all you have is internal
Agreed. We do the same. It would work better externally but price is exorbitant here for such options. We also do all the same as OP and it works really well. Especially opening early morning at dawn to cool everything down.
Well, the more light you reflect out the better (I would expect that, for example, darker color curtains would be a problem) and ideally you want that whatever light does get converted into heat does so outside.
As it so happens, were I live the heat has been a problem in the Summer since well before AC was invented, so roll-up external shades are standard for all houses and apartments and that stuff definitely works if used as I described it.
Those soakable cloth neck-wraps work as a cheap personal cooler($5).
The Coolify2 works as an expensive personal cooler(~$200).
If you have a fridge, freeze 2 litre ice-cream containers filled with water to make large ice blocks. Then put the block in a tub to melt, and sit your feet on it to stay cool(budget-mode, $cost of tap water)
If you’re in a humid environment and you have a way, dry the air. It makes any other cooling thing you do more effective.
Wet T-shirt and sitting in front of a fan.
We naturally cool our bodies by sweating.
You can sort of hack that process by getting a t-shirt wet, putting it on, and allowing the moving air to help speed up the evaporation process.
WARNING: NOT FOR USE IN HIGH HUMIDTY.
Adding more water to an already hot and humid situation risks a Wet Bulb.
And suddenly all those wet t-shirt contest promoters out there became heroes instead of villians.

If the water coming out of your cold tap is cool (which it should be, since pipes are typically underground), then I think maybe it would still work because you could refresh the t-shirt with colder water occasionally. It’s just less than ideal compared to doing it in a dry climate.
It would cool you a little as the cold water absorbs heat, but you’d have to wring and repeat as soon as it heats up, which might end up being often

better when don’t wear a shirt, spray yourself with water and sit it from of the fan; the convection feels fantastic on your skin.
Aren’t you going to catch a cold?
No. A cold is a virus, you won’t catch one by cooling yourself.
That’s exactly what a virus that was trying to trick me would say…
C’mon Greg, don’t you wanna be cool 😈
But, if the virus is already present in your system, cool and wet conditions can lower the effectiveness of your immune system. Tmyk
I used to not have AC. I found the best strategy was to open up all the windows at night and let the cool night air in, and then as soon as I wake up I close all the windows, curtains and blinds to trap the cool air in and prevent the sun from heating it up through the windows. If you live in a house that has a basement and central heating, you could add some intake ducts down there and turn your furnace on to fan only mode to circulate the cool basement air into the rest of the house.
Funny to see this question here a few weeks ago did I see someone link this https://m.youtube.com/watch?v=Nqxjfp4Gi0k&feature=youtu.be
The video shows how to create a salt based pcm (phase change material). You can also buy packs like these but I thought it seemed more fun to create it myself, so it will be my summer project when the heat is not barrable. I think Putting it under a cap would do wonders.
my phone isnt letting me open the link, but is it the nighthawkinlight video?
Yes
