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
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.
