Dealing with the heat during the day is one thing, but dealing with it at night? That’s when things get insufferable. It’s difficult, if not impossible, to fall asleep when you’re sweating profusely and sticking to your sheets. We can’t all afford air conditioners, and sometimes need to make due with a simple ceiling or floor fan to move the air around a bit. Unfortunately, this can have some less than pleasant side effects, leading many to wonder
The answer is a little bit more complicated than we’d all like it to be, and it isn’t the same for everyone. There are certainly benefits to sleeping with the fan on: the white noise can actually help some people sleep better, the temperature can feel a bit cooler, and the circulation of air can keep icky odors away.
There are also some important downsides to consider, though, and yes — some of them have to do with getting sick

Drying Of The Throat/ Mouth
Leaving the fan running will lead to drying of the mouth and throat because it dries out the air in the room. Breathing the dry air will dry the mouth for mouth breather and the nose for the nose breathers and hence disturbing your sleep since you might need to wake up to drink some water.
Although drying of the mouth or nose might not have any severe consequences as long as you re hydrate, it can lead to gum and teeth problems in the long run.
Sinus irritations are one of the main shortcomings of sleeping with the fan running. And this is also because it dries the air in the room as you sleep. This dry air irritates the mucous membrane line the nasal passages.
When these membranes become too dry, they will try to resolve this problem by producing mucus which in turn causes blockage, build-ups and intense pressure on the sinus.
That annoying stiff neck that you always get every other morning when you wake up might be due to leaving the fan running as you sleep. And this is because the cool breeze that the fan produces can cause the muscles to tense up as it blows on your skin.
Most people will prefer to direct the breeze to their body so that it can cool them fast which is not the right idea since it can cause the muscles around the neck to tense up or even cramp. The continued muscle tightening is what causes you to wake up with a sore or stiff neck or even a shoulder pain in the morning.
Asthma/ Allergy Issues
If you are one of the many asthmatic individuals or are prone to getting allergies, sleeping with a fan on is not good because it can make the symptoms worse. And this is more so if you do not clean your fan regularly.
Fans will collect a lot of dust and allergens when not in operations and when you switch them on they will blow all that dust and all the other harmful things in it directly into your sinuses and lungs.
For allergy and asthma sufferers, this is a nightmare that they never want to experience as it not only makes it hard to sleep but will also make their conditions worse.
There are some other annoying side effects to leaving a fan on as well, like the fact that the dry air can cause dry eyes, especially if you sleep with contacts on (which you shouldn’t be doing regardless).
