What are the hazards of air conditioning to the human body

Air conditioning is an indispensable household appliance in our lives. Especially in midsummer. When the weather is hot, most people stay in air-conditioned rooms. But many people will have this experience. That is, staying in an air-conditioned room for a long time will cause dizziness and other physical discomforts. So what are the hazards of air conditioning to the human body? Below we will introduce you to the knowledge about air conditioning in detail.

Staying in an air-conditioned room for a long time will cause the sweat glands to close, affecting normal metabolism and secretion; while sitting still for a long time without exercise will cause imbalance in the neck movement, affecting the neck muscles, nerves, spinal cord, and blood vessels, which will eventually lead to local cervical spondylosis.

Once the cold air breaks through the fragile "defense line" of the respiratory tract, mild symptoms such as cold, such as coughing, sneezing, runny nose, etc., that is, upper respiratory tract diseases, may appear. This type of cold is commonly known as a heat cold. On the one hand, it is because people often go in and out of air-conditioned rooms, and the body cannot adapt to the uneven temperatures. On the other hand, since the air-conditioned rooms are closed, there are many people in the room and the air circulation is poor. If one person shows cold symptoms, it will quickly infect others.

It is common to see young people and fat people turning on the air conditioner at home all day, or coming in from outside sweating profusely, and setting the temperature very low. Some people even run under the air conditioner and blow it directly, just for a momentary pleasure. Little do they know that when blowing directly, the air flow rate will increase, the temperature will drop suddenly by 3℃-4℃, and they will feel dizzy. Moreover, the sudden cold air can easily stimulate the sudden contraction of sweat pores and cause headaches. I often hear people who often sit in air-conditioned rooms say things like “I feel dizzy, I see stars, and I tend to forget things.” This is a common brain nerve imbalance reaction caused by air-conditioning disease.

The anions contained in the air can inhibit the human central nervous system and relieve brain fatigue. However, the air conditioner absorbs too many anions, causing more and more cations in the house. The imbalance of anions and cations also causes the brain's nervous system to become disordered and unbalanced.

Try to avoid staying in an air-conditioned room for a long time. If conditions permit, it is best to keep the room temperature constant at around 24°C. If the temperature difference between indoor and outdoor is more than 7°C, open windows frequently to ensure indoor and outdoor air convection. It is best to turn off the air conditioner for 1-3 hours and open the windows to breathe fresh air. Natural cool air is best. If conditions do not permit, it is best to go to the outdoor corridor or other places with windows to freshen the air every hour.

The above is a detailed introduction to the harm of air conditioning to the human body. Through the above introduction, we can find that long-term use of air conditioning is harmful to the body. We suggest that although the weather is hot in summer, we should try to stay in air-conditioned rooms as little as possible. If you can't leave easily due to work needs, you can open the windows frequently to ventilate. When it’s cold, prepare an extra piece of clothing and put it on in time.
