Winter has bid farewell at the very beginning of spring. Heat has gradually started to set in. In this weather, people are running air conditioners constantly at home or in the office. When the temperature is high, AC air can be enjoyed. But is it right to run AC even in mild heat? Do you know which diseases will persistently follow you if you stay in AC almost all day long?

What problems can occur to the body if you stay in an AC for too long?

Dehydration problem

AC draws hot air as well as water from the air. As a result, staying in an AC for long periods can increase dehydration problems. Therefore, according to the doctor, one can stay in AC for 7-8 hours within 24 hours. More than this will increase physical restlessness.

Asthma problem

From young to old, most people nowadays have asthma problems. Due to the AC not running for many days, dust often accumulates inside. So as soon as cold air comes out, the dust inside the AC comes out. As a result, complex problems like allergic rhinitis increase further.

How long should children and elderly people in the house be kept in AC?

On this matter, Rudrajit says that children should not be kept in an AC for too long at all. Children have lower immunity compared to adults, so symptoms like catching a cold quickly or fever can appear. Along with this, children can also have sneezing, cough, and sore throat. Similarly, caution should be taken for elderly people. AC temperature can be kept higher, such as at 24 or 26 degrees. However, the doctor has advised that even this should not be for the entire night.
