Many rely on fans in their bedrooms during the summer to help them fall into a deep sleep amidst high temperatures. While these cooling devices can be an effective way to regulate your temperature at night, there are some negative aspects for overall health. Martin Seely, CEO and sleep expert at "MattressNextDay," says that "electric fans can do more harm than good, causing issues ranging from bothersome allergies to neck inflammation."
**Allergens and Asthma**
Seely explains that "the very thing that makes electric fans effective at making you feel cooler—circulating air throughout the room—can also spell bad news for your allergies and asthma." The device can spread dust mites, germs, pollen, and other allergens throughout the room. He added, "If you find yourself suffering from excessive sneezing, watery eyes, a runny nose, itchy throat, and even difficulty breathing, make sure there isn't dust on the blades of the electric fan. If your budget allows, it’s worth investing in a better fan that can purify the air by reducing pollen and dust mite particles throughout the room." However, if you wish to use your fan, the expert recommends regularly cleaning your bedroom to help alleviate allergies.
**Congestion**
The excessive airflow from the electric fan can dry out your nose and throat, leading your body to produce more mucus to stay hydrated. Seely states, "This can cause various side effects, including headaches, nasal congestion, and even sinus headaches." Fortunately, keeping hydrated can help prevent this, with the expert recommending drinking at least two liters of water daily.
**Dry and Irritated Eyes**
Similar to congestion, the excessive airflow not only dries out your nose and throat but also your eyes, which can lead to irritation. The expert indicated that "this is especially important for those who wear contact lenses as it increases the likelihood of dryness and irritation."
**Neck Stiffness and Muscle Pain**
Seely advises against directing the fan toward painful muscle areas throughout the night, as "concentrated cold air can cause your muscles to tense and spasm, resulting in more pain. You may notice stiffness in your neck from using an electric fan, so try refraining from using it for a few nights to see if you notice a difference."
