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


Spray your back and socks with water occasionally. Not the shoulders, that gives you rheumatism. Only works under max humidity of course.
That can’t be true. The rheumatism thing i mean
It was for me last summer. Spray shoulders -> aching shoulders a few hours later. Spray back -> nothing aches, and you can do thing as if it was 20°C instead of 35.
