To protect ourselves from the intense summer heat and sweat, we turn on the AC as soon as we enter our homes or offices. But have you ever noticed that many people suddenly start having a dry cough, sore throat and runny nose even on these hot days?
Often people think of it as a common weather viral infection. But medically speaking, the real cause of these mysterious dry coughs and respiratory infections is not an outside virus, but the AC in your room cooling you down. So let’s find out from a senior pulmonologist, Dr. Satish Chandra, how indoor AC can make your lungs and respiratory system sick.
There are two main scientific reasons behind how AC is transmitted in airborne throat. The first is the dryness of the air and the second is the pollution hidden in the AC filter. According to Dr. Satish, AC cools the room and absorbs all the moisture or water vapor in the air. When you sit in such a cold and dry environment for too long, the inside of your respiratory tract dries out completely when you breathe. This wet area actually acts as a protective shield that prevents bacteria and dust particles from reaching the lungs. As it dries up, the throat becomes tight, a severe dry cough and problems that hurt when you swallow something.
The second main reason is the dirty condition of the AC filter. After months of summer when the AC is not run or serviced, dust and fungus accumulate on the filter. When the AC is running, they can enter your lungs through the air and cause serious illnesses like allergies and asthma.
People often come in from extreme heat and leave the AC at 16 or 18 degrees Celsius, which is a big shock to the body’s temperature regulation system. During summer, AC temperature should always be kept between 24 degrees to 26 degrees Celsius. This temperature is considered most suitable for the human body and respiratory system. When it’s 42 degrees outside and you suddenly step into an 18-degree room, this sudden change in temperature constricts your veins and weakens your immune system, doubling your risk of infection.
A few things to keep in mind to take care of your lungs while in AC. Thirst is less in an air-conditioned room, but drink a little water or boiling liquid every half hour to keep your throat moist. Remove and clean your AC air filter every fortnight to prevent dust and mold from spreading indoors. Also, turn off the AC for an hour at least once a day and open the windows of the room to let in fresh air and escape the bacteria that have built up inside the room.
