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.

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.

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.

Live in a dry climate. The evaporating water will cool the house. Doesn’t work if the air is already wet

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.

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.

But, if the virus is already present in your system, cool and wet conditions can lower the effectiveness of your immune system. Tmyk

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.

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.

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.

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.

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.
