6 Reasons Why Sleeping With The Fan On Might Be Bad For Your Health


You might think that sleeping with the fan on is a good idea because it will keep you cool while you sleep.

But what you don’t know is that this could actually be bad for your health!

In fact, experts at Sleep Advisor say that sleeping with a fan at night can be bad for you.

In this article, we’ll look a little deeper into why that is and describe exactly how sleeping with a fan on can be bad for your health.

Let’s dive in.

1. Dry skin

According to the experts, sleeping with the fan on can cause dry skin, which can lead to irritation.

That’s because the fan causes dry air, which decreases your skin’s moisture.

To avoid dry skin, you can use a humidifier.

If you have your fan on all throughout the night, it’s best to keep the humidity level of your bedroom at 30-50 percent.

You may also apply moisturizer right before going to sleep so that it will be fully absorbed by morning.

2. Stuffy nose and sore throat

Another reason why you should avoid sleeping with the fan on is that it can lead to a stuffy nose and sore throat.

The fan can cause your mucus membranes to dry out, which is why you might experience a sore throat or stuffy nose when you wake up.

Still not convinced?

According to Healthline, the constant circulation of air from the fan can dry out your mouth, nose, and throat.

This might cause excessive mucus production, which can lead to a stuffy nose or sore throat.

If you’re someone who has a stuffy nose or sore throat in the morning, then it might be best to sleep without your fan on.

3. Stiff neck

Sleeping with a fan on also causes neck stiffness, according to the experts.

They say when the fan breeze is directly on your face, it can cause neck stiffness, which is often accompanied by pain.

In fact, sleep Advisor warns people who sleep with a constant breeze directly on them may wake up with stiff or sore muscles.

To avoid stiffness in the morning:

Experts suggest that you keep the fan on a low setting and have it face away from you so that it won’t blow directly into your face.

4. Triggers allergic reactions

Another potential negative aspect of sleeping with a fan is that it can trigger allergies.

Believe it or not, fans can circulate dust, mold spores, and other allergens.

When you breathe in these particles, they can cause an allergic reaction.

And according to experts, you could experience symptoms such as coughing, sneezing, and itchy eyes.

Most importantly…

According to Sleep Advisor, if you’re prone to allergies, asthma, and hay fever, sleeping with a fan on can cause your symptoms to get worse!

That’s why it might be best to avoid sleeping with the fan on if you suffer from any of these conditions.

5. Sinus infection

According to experts, sleeping with a fan on can cause a sinus infection.

When the air is constantly circulating from the fan, it causes dryness and irritation in your nose and throat – which may be why you experience a sinus infection when you wake up!

In fact, you could experience symptoms, such as a stuffy nose, runny nose, sinus headaches, and even sore throat.

6. May aggravate muscle aches

Finally, another reason why sleeping with the fan on could be bad for your health is that it can cause muscle aches.


Because the concentrated cool air can cause your muscles to tense up while you sleep.

And according to the experts, this could lead to more muscle aches and pains when you wake up in the morning.


There are a variety of reasons why sleeping with a fan on might be bad for your health.

For example, experts say that it can cause dry skin and trigger allergies.

They also warn that it might be best to sleep without the fan if you have a stuffy nose or sore throat.
