As nighttime temperatures rise, many people rely on a fan while sleeping to stay cool and comfortable.
According to The Independent, doctors say that using a fan can improve sleep quality by promoting sweat evaporation and helping the body feel cooler.

However, continuous airflow directed at the body throughout the night may cause health problems for some people, including:
Worsened allergies and asthma: Air currents can circulate dust, pollen, and pet dander, while fan blades may disperse accumulated dust, increasing the risk of coughing, wheezing, or nasal congestion in people with respiratory allergies.
Muscle stiffness and aches: Prolonged exposure to cool air on one part of the body can lead to muscle tension or stiffness, particularly in the neck and shoulders.
Nasal and throat congestion: Constant airflow can dry out the nose, mouth, and throat. In response, the body produces more mucus, which may result in nasal congestion, a sore throat, or sinus headaches.
Dry skin and eyes: Continuous exposure to moving air can increase dryness of the skin and eyes, which may aggravate conditions such as eczema, psoriasis, or dry eye syndrome.
Tips for Using a Fan More Safely
Avoid pointing the fan directly at your face or body throughout the night. Instead, use the oscillation (swing) mode.
Clean the fan regularly to prevent dust and debris from being circulated.
Keep your bedroom clean to reduce allergens.
If you experience dry nasal passages, consider using a saline nasal spray before bedtime.
