Sleeping with fans, aircons on

Sleeping

- 

In many parts of the world, especially during sweltering summer months, the steady hum of fans and the cool breeze of air-conditioners provide a much-needed escape from oppressive heat. For countless people, sleeping with these appliances on is simply a nightly routine. But some experts and health-conscious individuals have raised a pressing question: could keeping fans and air-conditioning units on overnight actually cause health problems?

The body’s core temperature naturally drops at night as part of the circadian rhythm. Cooler environments can, in fact, help signal to the body that it’s time to rest. That’s why many people find it easier to fall asleep in cooler rooms.

However, prolonged exposure to artificially cooled or moving air during sleep can have mixed effects on the body, depending on several factors, including humidity, air quality, and personal sensitivity.
