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


Fans is so good in high humid places because the movement of the air actually let your sweat evaporate and perform its cooling effect as intended.
A lot of A/C also works as a dehumidifier that helps on that front and keep you feeling cool indoors.
