Is Sleeping With a Fan Safe?
The answer isn’t as black and white as you might think. While sleeping with a fan on is generally safe, knowing the pros and cons is vital. We’ll cover these in the next section. Read on so you can make an informed choice.
What Are the Pros and Cons of Sleeping With a Fan On?
The Advantages Of Sleeping With A Fan At Night
It regulates your body temperature and keeps you cool.
Using a fan can keep you comfortable and cool on nights when the air is hot, thick and stagnant. It’ll help regulate your body temperature by lowering it, which is crucial for good sleep. Plus, who wants to wake up drenched in sweat?
It’s white noise that calms by blocking out background sounds.
The gentle hum of an electric fan is considered a form of white noise, which has a uniform intensity across all audio frequencies. The sound of a fan masks disruptive background noise and has a calming effect for better sleep. (Great news for folks who live in a city that never sleeps, right?)
It moves air around your bedroom, keeping it from going stale.
The air in any bedroom can become stale, especially when there’s no AC running. The great thing about using a fan at night is that it moves the air in your room around. It’ll help you breathe more oxygen (instead of all the carbon dioxide you exhale) for better sleep.
In fact, in Sleep Doctor, Michael J. Breus, Ph.D., recommends using a fan if the air in your room is stagnant. He says, “It helps me sleep not just by circulating the air and cooling the room, but also by creating a soothing white noise.(1)”
It’s cheaper than an AC.
Let’s face it. It’s the more economical option compared to an air conditioner. But we have to say that it's not as effective when it comes to keeping you cool on hot summer nights.
The Disadvantages Of Sleeping With A Fan At Night
It may dry out your eyes and skin.
For some, the consistent flow of cool air from a fan can lead to skin and eye dryness. This can be uncomfortable for those with skin ailments like psoriasis or eye conditions like dry eye syndrome. (Oh, and if you have dry eyes, an excellent sleep mask may protect your peepers from the fan’s air).
It could exacerbate asthma or allergies.
Using a fan at night can circulate dust, dust mites, pollen and other allergens throughout your room. Breathing any of these could worsen allergy or asthma symptoms. Plus, you might wake up sneezing or coughing with irritated eyes and a runny nose.
It might make you congested.
The continuous airflow of a fan can potentially dry out your nasal passages, mouth, and throat. In response to the dryness, your body makes more mucus than it should. This excessive mucus production may lead to uncomfortable symptoms like nasal congestion, sinus headaches and a sore throat.
It may circulate germs and viruses.
Using fans can potentially spread pathogens. However, this becomes an issue only when a lack of fresh outdoor air is circulating in your bedroom. Crack open your windows to let outdoor air flow through your bedroom so the fan can do the opposite: improve ventilation and help mitigate the spread of germs.
Can Sleeping With a Fan on Make You Sick?
Okay. So, this is when the debate heats up (Yep. Pun intended). Some believe that keeping a fan running while you sleep increases your risk of developing a cold or the flu.
The logic behind this is that a continuous breeze might lead to dryness in your nasal passages, which makes them more vulnerable to infections caused by airborne pathogens.
Meanwhile, others believe this is an outdated myth. Unless you sleep directly in the fan's breeze, the likelihood of getting sick is equal to what it would be in the absence of a fan.
However, it’s a different story when you’re already ill. Early Bird by Amerisleep states, “If you choose to use a fan while sleeping with a flu or cold, consider adjusting its settings or position so that it doesn’t blow directly on you.(2)”
And as we mentioned earlier, sleeping with a fan can exacerbate allergies or asthma. According to GoodRX Health, “People with asthma or allergies to indoor triggers like dust and mold might find that their cough or congestion is worse after sleeping with a fan on.(3)”
Is It Safe to Sleep with a Fan On All Night?
Given everything we discussed above, let’s keep this simple.
If you often experience dry eyes or sinus problems, there may be better choices than keeping a fan on all night. The continuous airflow can worsen these symptoms (like spending a night in the desert sans an oasis.)
But if it's just a question of cooling you down when you overheat, using a fan all night can be incredibly beneficial. Just ensure the fan is positioned so it doesn't blow directly onto your face.
However, sleeping with a fan all night can be a lifesaver if it's just because you tend to overheat. Just make sure to position the fan so that it doesn't directly blow on your face, and you should be good to go.
What Are Safety Tips for Using a Fan While Sleeping?
Now, let's move on to safety. Here are some tips for using a fan at night:
-
Keep the fan clean: An accumulation of dust in fans creates an ideal environment for allergens and bacteria to thrive. It’s essential to periodically clean your fan to ensure it remains hygienic and functional.
-
Mind the power cord: This might sound trivial, but it's more common than you think. Imagine waking at night and stumbling in the dark on a fan cord. Tripping could lead to injuries, so ensure the cord is neatly secured and safely out of your way.
-
Don't overdo it: Yeah, we know. A soft breeze can feel divine, but sleeping with a strong gust directly on your face isn’t ideal. (It could lead to some cons discussed earlier in this article.) Set the fan speed to moderate to prevent discomfort.
What Are Alternative Ways to Stay Cool at Night?
What if you're not a fan of fans (pun intended again)? Don’t fret. You have alternatives to stay comfortable and cool during sweltering nights.
-
Invest in breathable bedding: Choose airy, moisture-absorbing materials like bamboo, linen or silk to help maintain your body's optimal temperature for sleep.
-
Freeze your sheets: Here’s a cool hack. Fold up your top sheet, put it in a freezer-safe plastic bag and pop it in the freezer briefly before bed — instant cool-down!
-
Take a lukewarm shower: A calming shower or soak in the bathtub helps lower your body temperature, making it easier to drift off.
