With UK households facing hotter nights — and only 5% having air conditioning — many are turning to electric fans. But Dr. Naheed Ali, a health specialist, warns that sleeping with a fan all night may come with hidden health risks:
⚠️ Potential Health Risks of Sleeping with a Fan On
-
Dry throat & sinuses: Constant airflow can dry out your airways, causing:
-
Thicker mucus
-
Coughing or scratchy voice
-
Congestion that lasts all day
-
-
Worsened allergies or asthma:
-
Fans stir up dust, lint, dander, and pollen
-
These particles can trigger tight chest or sneezing
-
-
Muscle stiffness:
-
Exposure to a cold air stream can cause neck and shoulder tension by making muscles constrict
-
✅ Doctor’s Tips to Use a Fan Safely
-
Use a timer – Set the fan to turn off after the first 90 minutes of sleep.
-
Avoid direct airflow – Point it at a wall to reduce intensity.
-
Stay hydrated – Keep water nearby for dry mouth or throat.
-
Limit allergens:
-
Wash bedding weekly
-
Replace or clean air filters regularly
-
💡 Bottom line: Fans can help with summer sleep, but if you rely on them, use these precautions to avoid dryness, allergy flare-ups, or muscle pain.
