Is sleeping with a fan on is damaging your health?

But experts say the reality is not that dire.

"There's nothing about a fan that's toxic," said Dr. Len Horovitz, a pulmonologist at Lenox Hill Hospital in New York City. "There's nothing wrong with circulating air."

People need to take a nap or some sleep as it is very important, and you don't want to be sweating all night, Horovitz told Live Science.

Anything which causes rapid air movement, including a fan, can evaporate moisture from your mouth and nasal passages, drying them out, he said. Fans also circulate dust all over the place, which could bother people, particularly the ones who have allergies.

If you are using a fan which is turned on when you go to sleep, Horovitz said it's a good idea to keep it at a safe distance from your bed so that it won't blow right on you.

To shield you against dust and other allergens, he recommended keeping an air filter in the bedroom. He also suggested performing daily sinus irrigation with saline, which can help with dry nasal passages, congestion, and other nasal problems.

If you do sleep with air conditioning on at night, Horovitz said the air shouldn't be blowing directly on you and the setting shouldn't be lower than 68 degrees Fahrenheit (20 degrees Celsius).
