Experts Warn Maine Residents Not to Run Fans Overnight

While it might seem like the best way to stay cool during our Maine summers, experts are actually warning against it.

While there are plenty of ways to stay cool during the summer, running a fan—whether it’s a ceiling fan or one of those oscillating stand-up ones—might not be your best option. According to experts, keeping a fan on all night could actually come with a few surprising downsides.

So, with that in mind—who are these experts, and what authority do they have to give us advice on how and when to use our fans?

To explain the risks, MattressNextDay combined expert insights from their CEO and Senior Sleep Expert, Martin Seeley, with viral trends and common fan habits. They examined both the popularity of sleeping with a fan and the potential health side effects, offering science-backed reasons why it might not be the best idea.

Alright, now that we’ve covered that, what are the five reasons the experts at MattressNextDay have shared about why we shouldn’t run our fans overnight?

1. Electric fans don’t just circulate air—they also stir up dust mites, pollen, spores, and other allergens in your room.

If you suffer from allergies or asthma, this constant movement of airborne particles can lead to sneezing, itchy eyes, and breathing troubles, so keep your fan blades clean and consider upgrading to a fan with built-in air purification if possible.

2. Running a fan all night can dry out your nose and throat.

To compensate, your body may produce excess mucus, leading to a blocked nose, sinus headaches, and poor sleep unless you stay well-hydrated throughout the day.

3. The dry air caused by a fan can make your eyes feel itchy and irritated, especially if you wear contact lenses.

If this is an issue, try using a rotating fan that doesn’t blast air in one direction or take breaks from the fan to protect your eyes.

4. Breathing in dry, dust-filled air from a running fan can irritate your throat and lungs.

This can lead to nighttime coughing fits, but cleaning your room thoroughly and using a humidifier can help reduce the problem.

5. Sleeping with a fan blowing directly on you can cause muscles to tense up, especially if you already have aches or poor posture.

If you notice stiffness in your neck or shoulders, try redirecting the fan or using a supportive pillow designed to reduce pressure and stay cool.

And there you have it. For several reasons, we’re being warned and strongly advised not to keep our fans running overnight here in Maine.
