Chapter 1: Fans Can Make Sleep More Comfortable, But They May Have Unexpected Side Effects
On hot nights, many people rely on a fan to stay cool and fall asleep more easily. The gentle breeze can reduce discomfort from heat, helping the body relax and promoting better sleep. However, having a fan blow continuously throughout the night may cause certain effects that are often overlooked.
One common issue is waking up with a dry throat, dry nose, or irritated airways. Continuous airflow can reduce moisture in the nasal passages and throat, especially for people who already suffer from allergies, sinus problems, or respiratory sensitivities. In some cases, these symptoms may become more noticeable after sleeping with a fan running all night.
