Hi there, time to share ways to keep your home cool during hot times

So ok, usual ways I use:

  • open everything during night
  • close everything during day
  • external sheets on windows without shutters
  • some curtains to prevent heat from going upstairs

I was also wondering if plants could also help inside, any ideas ?

Share your advices !

Hot showers at night or when you’re feeling extremely overheated. Trust me, that’s way better than cold showers. First shower warm, then get soapy, and then shower as hot as you feel comfortable. I do this for over 10 years now and it’s amazing. My theory is that it heats up the body and due to the outside being cooler, it actually cools your body down - albeit 35°C. By the way I shower with ~42°C regular lol

Upvoting for visibility, but this seems insane and impossible to me. When I take a cold shower, I can feel the water stealing the heat from my back, because it's warmer when it hits my legs. It's crazy.

It's definitely taking heat away, for me, and I would die if I tried to take a hot shower on a hot day.

I start with a warm shower, like normal, then slowly turn it down until it's nice and cool, almost cold. But not ice cold. Feel way better afterwards.

This seems like a really bad idea and a great way to get someone to pass out and die in the hot water

Sheesh there is literally no thing so harmless that some internet rando won't claim its deadly

Your body is overheating so you heat it more?

This is not a solution to a problem, it is a problem itself

You'd be surprised how good the human body is at dissipating heat. We spent a good chunk of our evolution being savanna dwellers

Most overheating comes from dehydration causing surface capillaries to contract limiting how much heat the body can expel, drinking a small amount of hot liquid will not raise the core to dangerous levels but it will provide hydration and the signal to the capillaries to expand allowing more heat to be radiated out

Cold water does the opposite, closing the capillaries as the body thinks it needs to retain heat as now the core is rapidly cooling.

You know what's funny? I have experienced the inverse of this. I run pretty cool so always take warm or hot showers, but one time there was a cold snap and my water heater broke. We had well water so it was very cold, and down here we do not really have heaters designed to handle actual cold so the house was freezing too. So I had what was probably the most uncomfortable shower of my entire life, shivering and teeth chattering so fucking cold, thought I would die, but when I got out? The air felt almost warm, it was so pleasant not just because it was over, but because it somehow blunted the feeling of cold. I don't understand how chilling my core somehow warmed me (it usually works the other way) but it sure did.

At night here I do shower hot, I think the theory is that then when you lay down, your body temperature is dropping and that makes it easier to fall asleep.

Biologically: being hot all over makes your capillaries close to the surface of the skin expand so you can dump heat into the air quicker

A hot shower raises this above ambient, giving you even better capillary cooling for a while, plus hot water tends to evaporate quicker, taking more heat load with it.
