Turning on the air conditioner and closing the doors causes insomnia, fatigue, and hair loss: What do doctors say?

Here’s a clear summary of what doctors say about the effects of turning on the air conditioner and closing doors causing insomnia, fatigue, and hair loss:
Turning on the Air Conditioner and Closing Doors: Can It Cause Insomnia, Fatigue, and Hair Loss?
Many people believe that using air conditioning in a closed room can lead to health problems like insomnia, fatigue, and hair loss. Let’s see what medical experts say:
1. Insomnia and Fatigue
-
Dry Air and Poor Air Circulation: Air conditioners can reduce humidity and circulation, which might make the air feel dry and stuffy if the room is sealed tightly. This can cause discomfort, nasal irritation, or difficulty breathing for some people, potentially disturbing sleep and causing fatigue.
-
Temperature Effects: If the air conditioner is set too cold, it can affect the body’s natural temperature regulation, making it harder to fall asleep or stay asleep comfortably.
-
Noise: Some air conditioners generate noise that can disrupt sleep, especially for sensitive individuals.
2. Hair Loss
-
Direct Link is Weak: There is no strong scientific evidence that simply using an air conditioner or closing doors directly causes hair loss.
-
Indirect Factors: However, dry air from air conditioning may dry out the scalp, leading to dandruff or scalp irritation, which in rare cases could contribute to hair problems.
-
Stress and Poor Sleep: Insomnia and fatigue can indirectly affect hair health since chronic stress and lack of sleep may contribute to hair thinning or loss.
3. What Do Doctors Recommend?
-
Maintain Proper Ventilation: Avoid sealing the room completely. Allow some fresh air circulation to prevent stuffiness.
-
Set Comfortable Temperature: Keep the air conditioner at a moderate temperature (around 24–26°C or 75–78°F) for comfortable sleep.
-
Humidify the Air: Use a humidifier if the air feels too dry to maintain scalp and skin health.
-
Keep the AC Clean: Regular maintenance to avoid mold and bacteria buildup, which can cause respiratory issues.
-
Healthy Lifestyle: Manage stress, maintain a balanced diet, and ensure good sleep hygiene to prevent hair loss and fatigue.
Summary:
Doctors agree that air conditioners themselves don’t directly cause insomnia, fatigue, or hair loss, but improper use—like setting very low temperatures, poor ventilation, or very dry air—can contribute to discomfort, sleep disruption, and scalp dryness, which might indirectly affect your wellbeing. Proper usage and room ventilation are key.
