Many of us rely on air conditioning to sleep comfortably at night when the humidity rises during the monsoon. Even though the cool breeze can be a pleasant change in your life, you should think about the potential health risks of sleeping with the air conditioner on. Prolonged exposure to the cold, dry air of an AC unit can lead to a variety of health problems, including respiratory problems, dry skin, and disturbed sleep patterns.
We got in touch with Dr Shibal Bhartiya, Program Director, Community Outreach and General Wellness, Marengo Asia Hospitals Gurugram, who explained how sleeping with the AC on at night can affect your health.
1. Quality of sleep
The temperature of your sleeping environment greatly affects the quality of your sleep. If the room is too cold, it can make you uncomfortable and prevent you from falling asleep. If you tend to wake up feeling cold or need more blankets, consider adjusting the temperature setting or using a fan in addition to the AC to create a more comfortable environment.

The biggest problem associated with sleeping with air conditioning on is the effect it has on your respiratory system. Air conditioners cool and dehumidify the air, which can dry out the throat and nasal passages. This can aggravate asthma and allergy symptoms, especially if the AC unit is not properly maintained. Dust and mold buildup in the air filter can spread throughout the room, potentially causing respiratory problems. Regular maintenance and timely replacement of air filters are essential to minimize these risks.

Prolonged exposure to air conditioning can also affect your skin. The dry air produced by AC systems can cause skin dryness and irritation and worsen skin problems such as eczema. To combat this, consider using a humidifier to maintain an optimal level of humidity in your bedroom. Applying a moisturizing lotion before bed can help keep your skin hydrated.

When the body loses too much moisture due to dry air, dehydration symptoms such as headaches, dry mouth and lethargy can occur. To combat this, make sure your room has a water-based humidifier to add moisture to the air and drink plenty of water throughout the day to stay hydrated.

To avoid these problems, keep your room at a comfortable temperature and use proper bedding or layers to stay warm without overusing the air conditioner.
