Is It Bad to Sleep with a Fan On?

When the temperature’s reaching with the triple digits outside, you’re probably blasting your fan to keep yourself cool during those hot, muggy nights. But what if it’s bad to sleep with a fan? In this blog, we dive into the pros and cons of snoozing with a fan on, as well as some solutions to keep yourself cool and healthy while you sleep.

Maintains Comfortable Temperature

Warm rooms are a sure way to keep you up at night, which can lead to fatigue and a lack of concentration the following day. And if you’re a hot sleeper, expect night sweats when the temperature is rising. 

Fans provide a blast of air to help cool down your bedroom while you’re underneath your comforter. If you sweat at night, the breeze can help dry away excess moisture, setting you up for a cool, comfortable sleep. (Also consider upgrading to the SHEEX All Season Comforter for a lightweight option during hot summer nights).

Air Circulation

A closed-off room often feels stuffy since there’s no air movement. Also, the air can get stale and stenchy. Constant air circulation boosts your bedroom’s freshness and combats odors, leading to a more comfortable sleep environment. 

White Noise

Fans produce a sound that’s similar to white noise. White noise consists of a wide range of frequencies resonating together, which can help people fall asleep. If you live in a big, bustling city, consider getting a fan since it can drown out everything from car horns to noisy neighbors.

Cuts Down on the Electric Bill

Running your air conditioner during summer isn’t cheap, and it certainly shows on the electric bill. However, a fan can alleviate these expenses. The U.S. Department of Energy states that if you run an air conditioning unit and a fan simultaneously, you can raise your thermostat by four degrees without a change in comfort.

Cons for Sleeping with a Fan On

Provokes Allergies

If you’re susceptible to allergies, sleeping with a fan on may trigger an allergic reaction while you’re sleeping in your bed. Fans don’t just circulate air, but also dust, spores, pollen, and other allergens in the room. As a result, you may experience excessive sneezing, itchy throat, runny nose, and other symptoms that can cause sleep disruptions. 

Dry Air

The excess airflow makes the room’s air dry. This dry air can cause numerous effects on your body. For one, it can dry out your throat and nose. This excessive dryness builds up mucus, which can lead to headaches, sinusitis, and a stuffy nose. Also, the constant airflow may cause dry skin and irritation. Applying lotion or moisturizer might ease the problem, but it may not help people with excessively dry skin.

Muscle Aches

If you have a constant breeze blowing directly at you, you may wake up with stiff or sore muscles. Why? Concentrated cool air can make your muscles tense up and cramp. If you have pre-existing muscle pain, you may want to consider turning off the fan before laying your head on your pillow.
