There is actually no so-called 'air-conditioning disease' in medicine. This is just a sociologically diagnosed disease name, which usually refers to related diseases caused by air-conditioning. The air conditioner itself does not make people sick. The working principle of the air conditioner is that the compressor continuously circulates and compresses, evaporates the liquid into gas indoors, and absorbs heat to cool the room; compresses the coolant gas into liquid outdoors and releases heat so the outdoor fan It is blowing hot air. The indoor temperature is sucked outside, so as to achieve the purpose of cooling down. The reason for 'air conditioning disease' is often related to improper use of air conditioning! For example: 1. Dirty air conditioners working in a closed environment will accumulate a large number of molds, bacteria and germs inside. If the filter and drainage system are not cleaned in time, these bacteria will spread and multiply indoors, which will affect the human nervous system and respiratory system. , Immune system damage, especially the elderly and young children, can easily cause pneumonia. This is why some people are more prone to allergies in summer. Therefore, pay attention to the cleaning of the air conditioner before using the air conditioner every year, and carry out a major cleaning of the air conditioner every half a month or a month during the use process to avoid the spread of germs. 2. Too dry. Will blowing air conditioner dry throat and skin? The main reason is dehydration. If the air conditioner is turned on in the house, the water will evaporate, the room will become dry, and the skin will become dehydrated due to dryness. Over time, people will be prone to dry and throat irritation, colds, dry skin and discomfort, especially young babies. So in summer, drink plenty of water to replenish the water lost from the body and skin. The air-conditioned room is used with a humidifier to give the room a comfortable humidity, and take more showers to clean the skin from sweat and dirt, and to replenish skin moisture. 3. Too cold 26°C-28°C is the most comfortable temperature for the human body, one degree hotter and one less cold. It is recommended that the indoor and outdoor temperature should not exceed 8°C. The large temperature difference will increase the burden of human body temperature regulation, which will easily cause dizziness, dry mouth and so on. Nowadays, the hot weather of 40 degrees Celsius every summer is gradually no longer rare. In these weather, the indoor temperature difference of 8 ℃ cannot be guaranteed. But be careful not to exceed 26°C. 4. Too stuffy In summer, there is a big temperature difference between indoor and outdoor. In order to prevent the air-conditioning from leaking, people always wait for the doors and windows to be closed 24 hours a day. Doors and windows are closed tightly, and a large number of bacteria will accumulate in the room. In addition, the room temperature is suitable, and bacteria will multiply. Therefore, in summer, it is best to open windows for ventilation once 2-3 hours to allow indoor air to circulate and keep the air fresh. Reminder: People often say that air conditioners can absorb 'yang energy'. People who are too weak cannot air conditioners. Modern people stay in air-conditioned rooms for a long time in summer and should exercise more, such as running, walking, cycling and other outdoor exercises to enhance their physical fitness.
