Leaving your fan on while you sleep at night can cause you health issues

With the UK experiencing a surge in temperatures, reaching for an electric fan might seem like a quick fix to cool down. However, experts are warning that this common practice could have consequences when it comes to your health.

Despite their seemingly harmless nature, leaving an electric fan running all night might lead to a host of health issues upon waking. While they offer a breeze that can make our bedrooms more bearable, electric fans also have the potential to cause muscle cramps, dryness in the throat, respiratory troubles, general aches, nasal blockages, and skin irritation.

Sleep specialist Martin Seeley, CEO of MattressNextDay, is urging individuals to turn off their electric fans before hitting the sack. He highlights one particular concern as allergens and asthma triggers.

Seeley points out that an electric fan does more than just move air, it can also circulate dust mites, spores, pollen, and other airborne allergens. "So, if you find that you're suffering from excessive sneezing, watery eyes, a runny nose, itchy throats and even breathing difficulties make sure that there is no dust on the blades of your electric fan," he advised.

Martin notes that prolonged exposure to the airflow from an electric fan can also lead to congestion. He explains that the constant breeze can dehydrate your nasal passages and throat.

As a result, your body compensates by producing additional mucus to maintain moisture levels, which can lead to various discomforts. "Including a headache, stuffy nose and even a sinus headache," he added.

Drinking ample water, according to him, is a potent way to fight against the adverse effects of excessive warmth. "This is also recommended for those that have suffered from a poor night's sleep due to the heat, as even mild dehydration can cause you to feel even more drowsy and tired."

Another potential health hazard of operating a fan all night is dry eyes and irritation. The fourth health risk comes in the form of a stiff neck or sore muscles.

Martin details: "If you have any pre-existing muscle pains, perhaps from working out or from improper posture whilst working at a desk, you should refrain from directing the electric fan on this area throughout the night."

"This is because the concentrated cool air can make your muscles tense and cramp up, causing you even more pain. You may even notice that you've gained a stiff neck since using an electric fan so refrain from using it for a few nights to see if you spot a difference."

It's worth exploring budget-friendly alternatives to keep yourself comfortable during your sleep without having to depend on an electric fan.
