The result is so serious. What are the specific hazards?
1. The most vulnerable respiratory tract
Although the air conditioner will cover the quilt, it can only keep warm but not prevent disease. Air conditioning enters the human body from the respiratory tract. When you wake up, your nose and mouth dry, you will still have cold symptoms. Therefore, the air-conditioning invasion respiratory tract, sometimes is defensible.
2. Susceptible to cold
In summer, if the outdoor temperature is too high, the blood circulation of human skin will be accelerated, and heat will be discharged through sweating, so the body surface temperature will rise. If you go into a low temperature room suddenly from a high temperature outdoor, the peripheral blood vessels can't close and contract quickly, and the human body will lose a lot of heat. As time goes by, the cold accumulates in the body and gradually suffers from the cold phobia. This kind of person is prone to cold hands and feet, cold, gastrointestinal discomfort, diarrhea and other symptoms.
3. Brain nerves will be out of balance
People who often sit in air-conditioned rooms will say: 'I feel dizzy, dazzled and forgetful'. This is caused by air conditioning disease, the common brain nerve imbalance response. Some people turn on the air conditioner all day at home, or enter the house with sweat dripping from the outside, and adjust the temperature to a very low level. The sudden cold air is easy to stimulate, and the pores will contract suddenly, causing headache and dizziness.
4. Blow out the 'air conditioning leg'
In summer, if you wear shorts and short sleeves, in the air-conditioned room, the exposed knees will be in a low temperature environment for a long time, which will cause vasoconstriction and slow down of blood flow, so it is easy to induce knee joint diseases such as synovitis and bursitis. The elderly, the middle-aged women with weak resistance and the white-collar workers who have been sitting in the office for a long time are the high-risk people of air-conditioned legs.

Do not turn on the air conditioner before entering the house
When you are sweating in the outdoor sun, do not turn on the air conditioner when you go home. Because at this time, the pores are in the open state for perspiration, and the sudden cold wind is easy to make the temperature drop sharply, which can induce fever and cold. It is better to turn on the air conditioner 10 minutes later when you enter the room from the hot outdoor.
Don't turn on the air conditioner all night
When sleeping, the body temperature drops. If the air conditioner is turned on all night in order to keep cool, it is also easy to cause headaches, colds and other symptoms. Before going to bed, the air conditioner must be turned off or set to turn off regularly.
Window ventilation is the key

It is suggested that the elderly, children, pregnant women and other vulnerable groups can choose to go outdoors for appropriate exercise, breathe fresh air, sunbathe, strengthen the body's immunity, and appropriate sweating also plays a role in detoxification. Fans and baths can also be used to cool down properly.
Clean the filter screen frequently
If the air conditioning filter screen is not cleaned for a long time, it will lead to poor refrigeration effect and small air volume at the air outlet. The most important thing is that the dust on the filter screen may contain a large number of Legionella bacteria, which may cause slight headache and respiratory discomfort when inhaled into the human body, and even lead to lung infection and pneumonia. Before the long-term unused air conditioner is used again, it should pay more attention to cleaning.
