If the humidity is affecting your sleep, turning your bedroom into some kind of sauna, you might be tempted to turn to the comfort of a fan—but some experts are warning against it.
According to Sleep Advisor, sleeping with a fan on might not always be a great idea, health-wise. While having a fan does circulate air to make your room cooler and fresher, it can also circulate pollen and dust. Not great if you suffer from allergies, asthma or hay fever.
"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. If your nasal passages become too dry, Sleep Advisor warns that the body can produce excess mucous, making you feel all bunged up.
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.
