Electric fans work well only when temperatures are below 40°C. Beyond that, they can circulate hot air and actually increase body heat instead of cooling you down.

From Delhi to Rajasthan and beyond, soaring temperatures are pushing cities across India into intense heatwave conditions. With homes turning into heat traps, staying cool indoors is becoming just as challenging as stepping outside. But simple, science-backed changes—recommended by the World Health Organisation (WHO)—can make a big difference.

Shut Out The Day Heat: As the sun rises and outdoor temperatures climb, keep windows closed. Use blinds, curtains, or shutters to block direct sunlight. This prevents heat from entering and helps maintain a cooler indoor environment. (Image: Canva)

Cut Down Indoor Heat Sources: Appliances generate heat—even when you don’t notice it. Turn off unnecessary lights, electronics, and devices during the day to prevent your home from heating up further. (Image: Canva)

Let The Night Air Do The Work: When the sun sets and temperatures drop, open your windows. Cool night air can naturally ventilate your home, flushing out the heat trapped during the day. It’s one of the simplest ways to reset the indoor temperature without electricity. (Image: Canva)
