Sleeping with a fan on at night

The Downside of Sleeping with a Fan at Night

ChiliSleep Team · May 12, 2022
Sleeping with a fan on at night

Let’s face it, none of us like to sleep in a hot room. Sleeping in a roasting and stuffy space makes it more difficult to fall asleep, harder to sleep deeper, and impossible to stay comfortable throughout the night.

To address these problems and find some comfort this summer while sleeping, you might be finding yourself scrambling to find a fan, hoping it will keep you cool at night. This simple and relatively effective solution may not be as great as you think.

Did You Know? A fan will not actually cool your body temperature. Designed to circulate air in a room and help maintain moisture, a fan merely blows air out, creating a cooling illusion.

We’ll discuss the downsides of sleeping with a fan at night and a more effective solution to staying cool in bed all night long, resulting in deeper and more restorative sleep.

Don't Just Circulate Air, Cool Your Body Temperature

The various speeds on a floor or ceiling fan won’t stop you from waking up in the middle of the night sweating. Our sleep systems control your body’s temperature to keep you cool at night and help you sleep better.

Is Sleeping with a Fan on Bad for You?

Are you aware of the side effects of sleeping with a fan on you? If not, you’re not alone. Sleeping with a fan poses some health risks. Although most of these health problems are minor and often more irritating than anything else, they are significant enough to reconsider using a fan while sleeping.

Stay Cool Without Using a Fan This Summer  

Below we’ll discuss the main concerns with using a fan while you sleep and the negative effects on your health.

1. Allergies

If you are allergic to pollen or dust, a dirty fan may be making things worse. A fan blowing throughout the night stirs up the air and circulates pollen and dust around your bedroom. Inhaling these allergens may make your symptoms worse.

Studies show that seasonal allergies contribute to sleep disorders, snoring, and lower quality sleep. [1]

Bedroom Fans and Allergies

Over time, household allergens and dust mites can build up on the ceiling fan blades without you knowing.

2. Sinus Irritation

Air from your fan can irritate your sinuses and dry out your nose, mouth, and throat. In response to this, your body may start to overproduce mucus, which can cause congestion (stuffy nose), sore throat, and headaches. If you’re already under the weather, it can worsen your symptoms.

3. Sore Muscles

Ever wake up with sore muscles or a stiff neck? Circulating air throughout the night may cause your muscles to tense. This is specifically harmful if you have the fan pointed close to your face and neck. If using a fan, point the fan away from you at night, so the air doesn’t blow directly on you.

4. More Likely to Wake Up

Did you know that the air movement around you at night may wake you up, increasing sleep disturbances? So what you use to improve your sleep may be disturbing it.

There’s Another Way to Stay Cool at Night!

Cooling Mattress Pad

Fans offer little benefits of keeping you cool at night, while potentially causing or increasing health issues. Instead of a fan, there are options on how to stay cool at night, including the use of our cooling mattress pad.

They are designed to help prevent you from overheating and stay comfortable and cool all night long. Typical mattresses trap your heat and reflect that heat right back towards you, making it difficult to keep cool.

However, our cooling mattress pads regulate your temperature, preventing you from overheating and sleeping hot.

Cooling Mattress Pads Features

The science is clear, we sleep deeper with increased recovery at a cooler temperature. Below are some features of our ChiliSleep Sleep Systems and differences in how they can cool your body compared to a fan.
