What is the relationship between air conditioning and health?

American scientists have conducted a long-term comparative survey of residents who use air conditioning and those who do not use air conditioning in Birmingham and Manchester, and found that the incidence of the former is more than 5% higher than that of the latter. Symptoms are mostly nasal congestion, dry throat, headache, chest tightness, lethargy, cold and so on. Especially the incidence of rhinitis is more than 5 times higher. This shows that air conditioning enters the home, setting the best temperature for people, making people enjoy cool and comfortable, but also affecting people's health.

So, why does air conditioning affect health? This is because air conditioning equipment provides circulating air. Although the air after dust removal is clean, it is not fresh, and it lacks sufficient negative ions in the air and is indispensable to human body. In other words, air conditioning equipment reduces the indoor negative ion concentration. According to the measurement, there are about 50 negative ions per cubic centimeter in an ordinary room, which is reduced to below 10 after installing air conditioning equipment. The decrease of negative ions will increase the concentration of selenium in human plasma, which will lead to insomnia, irritability and mental stress of indoor personnel. In addition, because air-conditioned rooms are generally closed, indoor pollution (such as bacteria, trace radiation, etc. ) It's getting worse. In addition to causing lung and respiratory diseases, it can also cause limb pain, chills, conjunctivitis, abdominal pain, mouth deviation and eye deviation, and female nervous disorder, which is a popular disease in recent years-air conditioning disease.

Are we helpless in the face of air-conditioning disease and can only let it endanger our health? Of course not. In fact, as long as you use air conditioning correctly, you can enjoy the benefits of air conditioning easily and healthily. Here is how to use air conditioning to prevent air conditioning diseases:

(1) Using disinfectants can kill microorganisms in air-conditioning equipment. Disinfectants should be used repeatedly to prevent the growth of microorganisms.

(2) Because the humidity regulator of air conditioner is a tool to promote the spread of bacteria, it will bring bacteria to every corner. Therefore, indoor relative humidity should be reduced and dehumidifiers should be added to prevent bacterial growth.

(3) When sweating after strenuous exercise, don't enter the air-conditioned room immediately, so as not to make the open pores suddenly contract and get sick with cold.

(4) It is not advisable to stay in an air-conditioned room for a long time. You should give your skin a chance to sweat, do more exercise and drink more boiled water, so that your pores are unobstructed, thus speeding up your metabolism.

(5) The temperature difference between the air conditioner and the outdoor natural temperature should not exceed 5℃.

(6) If possible, it is best to use an open system air conditioner to keep the indoor and outdoor air circulation fresh.
