4 Ways Sleeping With A Fan Is Actually Harmful To Your Health, According To Science

In order to battle the summer heat when sleeping, the fans come on. But is it doing you more harm than good?

Coming home after a long day and plopping yourself on the bed may just be one of the best and most relaxing feelings. Slowly nodding off, you're just about ready to fall into a deep slumber. However, there's something keeping you up. You're extremely tired but you're just not able to fall asleep. And the reason may be because of that fan that is keeping you cool at night, especially during those harsh summer nights.

While many people love running their fan because it keeps them cool, many others also love the sound that it makes. The constant whirr can be lulling but it can also distract you from the ambient night noises which can otherwise come off as eerie.

However, recently there has been news that sleeping with a fan at night can be dangerous for your health. A headline by the Mirror UK read "Why sleeping with your fan on could be seriously damaging your health." It states that no matter your physical or psychological issues with sleep, having the fan on can do more harm for your health than you realize. And here are the ways it can negatively affect you:

1. It can stiffen your muscles

Sleeping with the breeze directly on you might be the reason you wake up with stiff or sore muscles. Leaving the fan switched on at night results in the concentrated cool air to cause your muscles to tense up, leading to cramps. So if you've been waking up with a stiff neck in the morning, it could be because of the constant breeze, especially if its kept near your neck and face.

2. It induces the "Drying Effect"

The fan's circulation of dry air can leave you waking up feeling weary, extremely thirsty and dehydrated. It can also be the reason why your eyes feel dry and your nose feels clogged. For those who also have a history of nosebleeds, this effect can be the reason they face it when they wake up. 

3. It can lead to sinus irritation

Along with drying up your eyes and making you feel dehydrated, the constant stream of air also has a tendency to dry out your nasal passages. This, in turn, can affect your sinuses. If the dryness is extreme then your body tries to compensate by producing extra mucus which then leads to nose blockages, stuffiness and sinus headaches.

4. It causes your allergies to act up

According to The Sleep Advisor, as the air from the fan circulates the room, it causes resting dust and pollen to enter your sinus, especially if you leave your windows open. And when you're sleeping, this could cause a lot of medical issues. Take a look at the blades of your fan. If it is starting to look a color that wasn't the one the fan originally came with, it's because there is dust gathering on it. So every time you turn it on, those same dust particles are making its rounds through the air.

However, if you're one of those people who absolutely cannot sleep without the fan, it's okay. After all, you may have gotten used to it or are comforted by the sound. "There's nothing about a fan that's toxic," said Dr. Len Horovitz, a pulmonologist at Lenox Hill Hospital in New York City, reported Live Science. "There's nothing wrong with circulating air." To battle the downsides though, he suggests keeping your fan a safe distance from the bed and not have it blow directly on you. To guard against dust and other allergens, he also recommends keeping an air filter in the bedroom.
