Air conditioner usage errors can be harmful

What do the experts say?

Experts say that sudden drops in temperature from hot to cold can be harmful to the body, especially for people with chronic cold-related illnesses.

The sudden and extreme change between the temperature in an air-conditioned room and the hot sun outside can be harmful to the body. It puts stress on the body as it is forced to adjust itself from too hot to too cold, according to the Times Of India.

Sudden changes between the temperature in an air-conditioned room and the hot sun outside can be harmful to the body.

This sudden change in temperature can dry out the skin, mucous membranes and eyes. Many people experience itchy eyes and sneezing as soon as they arrive at the office, which can be caused by the temperature difference between the air-conditioned room and the outside. This can even cause eye and respiratory infections and muscle spasms.

Other problems that can occur due to a sudden drop or rise in temperature are runny nose, asthma attacks, muscle aches, sinusitis, flu, colds, sore throat, severe pain and muscle aches.

The same goes for stepping out of an air-conditioned room. If the outside temperature is too hot, turn off the air conditioner for a while before stepping out, according to Times Of India .

Dr. Suranjit Chatterjee, Apollo Hospital (India), said the body needs time to adapt when moving from extremely hot to extremely cold temperatures or vice versa.

When the temperature changes too suddenly, the blood vessels will be affected. Dr. Chatterjee said that sudden temperature changes affect the temperature of the blood vessels, which in turn affects the heart.

It is advisable to change the temperature gradually to avoid affecting the body system. Sudden temperature changes will affect the immunity and that is why people often get sick or infected with viruses when the weather changes suddenly.

Dr Romil Tikku, Max Hospital (India), says that sudden changes in temperature can cause extreme discomfort for people with respiratory problems. Patients with asthma, sinusitis and other respiratory problems may experience acute illness. Cardiac events in people with heart disease may also occur.

Many people often have the habit of turning on the air conditioner as soon as they enter the house.

Dr Tarun Sahni, Apollo Hospitals, said that sudden changes in temperature can affect the body's natural reflexes, which can hamper the brain's protective layer. This increases the risk of viral infections and allergies.

Sitting in an air-conditioned room for a long time can make you unable to bear the heat when you go outside. This can easily make you exhausted when exposed to outside temperatures, which can cause dizziness, fatigue, headaches, shortness of breath, and even heat stroke.

What to do?

Do not change suddenly from too hot to too cold or from too cold to too hot.

If you need to go out from an air-conditioned room, turn off the air conditioner for a while to let your body get used to the heat outside.

And when coming in from outside, don't turn on the air conditioner immediately, but switch to using a fan to cool down gradually before turning on the air conditioner, according to Times Of India.
