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
