Does sleeping with air conditioning regularly affect the lungs?

Master, Doctor Tran Thi Thuy Tuong , Department of Respiratory Function Testing, University of Medicine and Pharmacy Hospital, Ho Chi Minh City, replied: With the impact of climate change, hot summer weather has greatly affected work productivity and contributed to negative impacts on health.

The use of air conditioning has also been proven to bring certain benefits to work performance, as well as bring comfort to people, including hospitalized patients. However, regular use of air conditioning, keeping the temperature too cold will negatively affect respiratory health.

Using air conditioning regularly and setting the temperature too cold will negatively affect respiratory health.

Cold air easily dries the nasal mucosa, which helps protect the respiratory tract and prevent bacteria or viruses from entering the lungs and causing inflammation, especially for people with chronic respiratory diseases such as chronic obstructive pulmonary disease, bronchiectasis, the elderly, many underlying diseases, and weak resistance. Many studies have shown that air that is too cold will make people with asthma or hypersensitive lung disease more susceptible to bronchospasm, causing acute asthma attacks.

The temperature difference between the outside environment and the room is too high, which will cause the body to not have time to adapt, causing heat shock. To be safe, air conditioner users should not let the difference between the ambient temperature and the air conditioner temperature exceed 7 degrees. Always keep the room well-ventilated and clean the air conditioner periodically, because infectious agents can exist in a closed environment, adversely affecting respiratory health.

Air-conditioned bedrooms should be cleaned regularly. In the morning after using the air conditioner for many hours overnight, open the windows to let in the sun and wind to help disinfect and circulate the air.

When sleeping, avoid sleeping where the air conditioner blows directly on your face or head as this can cause nasal congestion and sore throat. Additionally, to create humidity in the air when using air conditioning, you can place a pot of water in a corner of the bedroom.
