Why experts don’t always recommend sleeping with a fan on

Has anyone else noticed that it’s a little… warm right now? Like, really warm? And for many, this deep humidity can have a major impact on sleep – after all, having a bedroom that’s part-snooze station and part-sauna can be pretty uncomfortable. The obvious solution for sleeping in the heat? A fan! Right? Erm, unfortunately (and we hate to be the ones to break this to you) some experts are actually warning against sleeping with a fan on.

According to Sleep Advisor, sleeping with a fan on might not always be a great idea for health-related reasons, as although having a fan on will circulate air to make your room cooler and fresher, it can also circulate pollen and dust. Which isn’t ideal if you suffer from allergies, asthma or hay fever (which has also ramped up for many at this time of year).

“Take a close look at your fan,” the Sleep Advisor suggests. “If it’s been collecting dust on the blades, those particles are flying through the air every time you turn it on.”

Other reasons not to sleep with a fan on include the fact that it can dry out your skin, as well as your nasal passages, and if your nasal passages become too dry, Sleep Advisor warns that the body can produce excess mucous, making you feel all bunged up come morning time. Not ideal…

And then there’s muscle cramping. “People who sleep with a breeze directly on them may wake up with stiff or sore muscles. This is because the concentrated cool air can make muscles tense up and cramp,” the experts explain. “This problem is especially common for people who sleep with it near their face and neck. If you’ve been waking up with a stiff neck in the morning, it might be because of the constant breeze.”

On the flip-side, the article does point out that fans in the bedroom can work well for people as provide comforting white noise to help people drift off to sleep when it’s stuffy.

But if you’re prone to allergies, it could be worth trying other options like a cool flannel in a bowl of water near your bed, or sleeping on top of the covers with the window open. Happy sweating either way, folks!
