The fan is a cost-effective way to keep you cool during the hot and humid summer nights. But sleeping with the fan on may trigger congestion, dryness, sore muscles, or allergic reactions in some people. If you have allergies but sleep hot, try using air filters and humidifiers to reduce symptoms of allergies.
Is it safe to sleep with fan on?
Circulating air from a fan can dry out your mouth, nose, and throat. This could lead to an overproduction of mucus, which may cause headaches, a stuffy nose, sore throat, or even snoring. While a fan wont make you sick, it may worsen symptoms if youre already under the weather.
Why do I have to sleep with a fan on?
The main reason most people buy fans and use them while sleeping is because they control the temperature in a room and can keep you cool. A fan circulates air over the body, encouraging the core body temperature to drop. Fans also create a breezy feeling, which is why so many people use them with air conditioners.
Should you leave a fan on all night?
As well as posing a potential fire risk, leaving a fan running all night could pose some health risks as well. The rapid air movement caused by a fan can dry out your mouth and nasal passages, your eyes and can even cause dry skin conditions, according to Mark Reddick from Sleep Advisor.
