Doctor issues warning over alarming health risks of sleeping with fan on during hot weather
The constant airflow can dry out your sinuses and throat, leaving you feeling dehydrated and that dry throat sensation the next morning, the senior contributor at Vera Clinic said.
“A dry airway produces thicker mucus, which can trap allergens and irritants close to sensitive tissue,” Dr. Ali explained. “Over time, this may trigger coughing, a scratchy voice, or clogged sinuses that linger through the day.”
For those with asthma or allergies, running a fan overnight can ‘stir up’ dust and lead to chest tightness, the physician added.
