In the scorching summer, the scorching heat is unbearable, and most areas across the country have entered the high temperature mode. Air conditioning has become an indispensable tool for summer heat, and "air conditioning disease" has also followed.


"Air conditioning disease" is also known as air conditioning syndrome. It is not a conventional disease, but the symptoms it brings should not be underestimated.


Cold: Although the symptoms of cold are similar to colds, colds are not colds. When the temperature difference is too large, in order to fight against low temperature, the human body temperature regulation center will make adjustments urgently, and people may have nasal congestion, runny nose, diarrhea and other symptoms, which is a cold.


Allergic diseases: If the indoor air is not circulating and you are a person prone to allergies, it may cause rhinitis, itchy eyes, headache, dizziness and difficulty breathing. In more serious cases, it may cause pneumonia or asthma;


Dry nasal cavity and skin: Due to the cooling mechanism of the air conditioner, the relative humidity of the cold air blown by the air conditioner is mostly low, which may cause dryness of the nasal cavity and skin;


Upper respiratory tract infection: The dry nasal mucosa reduces the resistance of germs from entering the human body from the respiratory tract, making people more likely to suffer from upper respiratory tract infections;


Inability to tolerate high temperature: staying in an air-conditioned room for a long time, once you go out, it may be difficult to tolerate high temperature;


Spreading diseases: Offices or large indoor public places, these environments are all areas with relatively high population density. Once one of them gets sick, it will quickly spread to other people when the air is not circulating.


Why are these symptoms related to air conditioning? This starts with some characteristics of the air conditioning and refrigeration process.


Air conditioning refrigeration is achieved by blowing out cooling air from the indoor unit (evaporator). In this process, the water vapor in the indoor air condenses into water droplets in the evaporator and flows to the outdoors along the drain pipe, so that the indoor air will become dry. In addition, in order to ensure the cooling effect of the air conditioner, we generally close the doors and windows when the air conditioner is turned on, which also causes the indoor air to not circulate, and diseases are more likely to be transmitted in such an environment.


How can we prevent "air conditioning disease"?


(1) Whether it is a young or middle-aged friend, when turning on the air conditioner, do not allow the temperature difference between indoor and outdoor to be too large. The room temperature can be kept between 26℃~28℃;

(2) Ask professionals to repair and clean the air conditioner regularly, at least once a year;

(3) Use a humidifier to make the indoor humidity between 60% and 70%. Studies have shown that when the air humidity is around this range, the infection ability of cold viruses can be rapidly reduced;

(4) When people are not indoors, turn off the air conditioner and open windows for ventilation;

(5) Develop the habit of drinking water and moisturizing the skin.


The hot summer is still long, so when you enjoy the coolness brought by the air conditioning, you must also master the correct posture!


In addition, there is also a kind of "car air-conditioning disease" that also needs to be careful!

Here to remind all riders:

★ Do not sleep in an air-conditioned car

Because of the poor ventilation in the car, if you sleep with the air conditioner on, you may be poisoned by the carbon monoxide gas discharged from the engine leaking into the car.

★ Open the window first, then the air conditioner

A car parked in the scorching sun shouldn’t get in immediately. The temperature should be lowered first, but it does not mean turning on the air conditioner immediately.
