Sleeping with a fan on is a common way to cope with heat, but doctors say it may have some downsides for certain people. Experts point out that constant airflow can circulate dust and pollen, potentially triggering allergies and breathing issues. It may also dry out the air, leading to problems like sore throat, sinus irritation, and dehydration. Some people can experience congestion due to excess mucus production, while direct airflow may cause muscle stiffness. In addition, the noise from a fan can disturb sleep for light sleepers.
