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


I grew up here in Florida without air conditioning until I was about 25.
Really just learned to be still, that helps. Keep the windows open at night if it cools off at night.
Stay in the shade, if there is a breeze it is not bad. Fans, fans, fans. Carry a parasol if possible . Shade helps so much.
And I wait for the rainy season, ours is at the same time of year yours is. Love that time, every day it gets hot but then in the afternoon the rain comes.
ETA I think India has this covered already but stay away from synthetic fabric and cotton. Linen or silk are best, and oddly, light merino wool in a loose fit is also so good in the hot weather.
Thank you
