In hot summer, why do you need to open the window for ventilation when you turn on the air conditioner?

In hot summer, air conditioning has become an indispensable household appliance, but when you turn on the air conditioner, you must always open the window for ventilation, which is of great benefit to everyone's health. If you turn on the air conditioner and don't open the window for ventilation, it may lead to the deterioration of the indoor air environment and easily lead to the illness of indoor personnel.

First, turn on the air conditioner for a long time, and there is a lot of carbon dioxide in the air in the closed space. If we stay in an air-conditioned room for a long time, we are more likely to catch a cold because we have not been exposed to the sun for a long time. Second, if the air conditioner is turned on for a long time without opening the window for ventilation, there will be dust and viruses in the air. Once dust and viruses enter our bodies, they will do harm to our bodies. The third point is that in an air-conditioned room, because the air conditioner is constantly changing air, in order to maintain normal air humidity, the air conditioner will absorb indoor humidity. I wonder if you will feel this way. Staying in an air-conditioned room for a long time will make you feel dry. In severe cases, there may even be cough and dizziness. In fact, this is all caused by air conditioning.

Think about it from another angle. What are the benefits of opening a window for ventilation? First of all, the first point is that relatively speaking, window ventilation can avoid catching a cold to some extent. Secondly, window ventilation can take away carbon dioxide and viruses in the air, effectively remove harmful substances in the air, and play a role in purifying the air, thus promoting human health. In addition, opening the window can let the sun shine directly indoors, and the use of sunlight and ultraviolet rays can play a role in sterilization.

In summer, we can't stand the high temperature environment. We can turn on the fan and air conditioner to reduce the indoor temperature and achieve a cool effect. While preventing high-temperature heatstroke, we also need to consider the endurance of the body and maintain a normal health level. Try to avoid staying in an air-conditioned room for a long time, keep your body cool, and remember to exercise outdoors, receive ultraviolet radiation and supplement more calcium. Bian Xiao is here to give you advice again. Turn on the air conditioner for a long time, and be sure to open the window for ventilation. I wish you all a happy and healthy summer vacation.
