Summer is in full power here in Kerala, India. Concrete radiating heat and rooms are hot even at night. Have seen people mention things like blackout curtains, reflective or white paint on the roof etc. Have upped hydration and am now sleeping with windows open, with a mat on the floor. What all things do the people in your locality do? Or if you have any specific insight into cost-effective techniques or so, could you kindly share them? Thanks in advance

So, a lot of this is duplicated, but it’s a list of what I do against the heat … External shutters outside of the windows, both are closed the moment the sun hits to shut in the cold(er) air, and open over night. We also have tiled shades over all the windows so there’s no direct sunlight into the house during most of the day. Ceiling fans running at low speed Cold 2 minute showers in the middle of the day Put on a cold wet t-shirt Wear as little clothing as possible while out of the sun. In the sun, light coloured breathable loose material (linen trousers are a godsend against mosquitoes) Don’t go outside or be active in the hottest part of the day Don’t eat much, if at all, during the day And my wife’s favourite - getting in a kid’s paddling pool (I don’t like it, but she does)
