Air conditioning brings you comfort, but it can also cause you these diseases!

In this kind of weather, anyone who dares to go out must be a descendant of the sun! The sons of air-conditioning are only suitable for air-conditioning + wifi + lying like Ge You.

Air conditioning can be said to be the savior-like invention of the 21st century. It saves humans from the suffering of scorching heat. However, good things cannot be used too much. Using too much air conditioning can cause harm to the body, and in more serious cases it can even lead to facial paralysis. The result is so serious, what are the specific dangers?

1The respiratory tract is the most vulnerable

Although we always cover ourselves with a quilt when using air conditioning, it can only keep us warm but cannot prevent us from getting sick. The cold air enters the human body through the respiratory tract, and when you wake up your mouth and nose will be dry, and you will still have cold symptoms. Therefore, it is sometimes difficult to prevent cold air from invading the respiratory tract.

2. Susceptible to "cold fear"

In summer, when the outdoor temperature is too high, the blood circulation in the human skin will accelerate, and the body will dissipate heat through sweating, thus increasing the body surface temperature. If you suddenly walk from a hot outdoor environment into a cold indoor environment, the peripheral blood vessels will not be able to close and contract quickly, and a large amount of body heat will be lost. Over time, cold air accumulates in the body and people gradually develop "cold fear syndrome". Such people are prone to cold hands and feet, colds, gastrointestinal discomfort, and diarrhea when exposed to air conditioning.

3 Brain nerves will be unbalanced

People who often sit in air-conditioned rooms will say: "I feel dizzy, see stars, and tend to forget things." This is a common brain nerve imbalance reaction caused by air-conditioning disease. Some people turn on the air conditioner at home all day long, or come in from outside sweating profusely and set the temperature very low. The sudden cold air can easily irritate the pores, causing sudden contraction and leading to headaches and dizziness.

4. Blow out "air-conditioned legs"

Wearing shorts and short sleeves in the summer and staying in an air-conditioned room will expose your knees to a low temperature environment for a long time, which will cause vasoconstriction and slow blood flow, which can easily induce synovitis, bursitis and other knee joint diseases. The elderly, middle-aged women with weak resistance and white-collar workers who sit in the office for a long time are at high risk of "air-conditioning legs".

Long-term strong cold air can cause great damage to the joints. If you don't pay attention to keeping warm at this time, you will easily suffer from arthritis when you get older.

The air conditioner should blow like this

26 degrees is the most suitable

The temperature that the human body can easily adapt to is 26℃. If it is lower, the body will feel too cold. If the temperature difference between indoor and outdoor is too large, the body's regulatory ability will gradually be disturbed, resulting in a decrease in immunity over time, so it is best to set the air conditioner to around 26°C.

Air conditioning blows upwards

Don't point the air conditioner towards your body. The air from the air conditioner is too cold. If it is directed directly at the body, it will cause cold air to enter the body, affect peripheral blood circulation, and eventually cause various arthritis. It is best to cover your neck with a scarf when using the air conditioner indoors, and cover your legs with clothes when wearing a skirt.

Don't turn on the air conditioner before entering the house

If you have been sweating in the sun outdoors, do not turn on the air conditioner as soon as you get home. This is because your pores are open to secrete sweat. A sudden burst of cold air can cause your body temperature to drop sharply and induce a fever or cold. It is best to wait 10 minutes after entering the room from the hot outdoors before turning on the air conditioner.

Don’t turn on the air conditioner all night

The human body temperature drops when sleeping. If you turn on the air conditioner all night to keep cool, it can also easily cause symptoms such as headaches and colds. Be sure to turn off the air conditioner before going to bed, or set a timer to turn it off.

Opening windows for ventilation is key

When using air conditioning, you must pay attention to ventilation. It is best to turn off the air conditioner every hour and open the windows to let fresh air circulate. To avoid respiratory infections caused by poor ventilation. Poor air circulation can also cause the indoor air to be too dry, resulting in symptoms such as nasal congestion and sneezing. If necessary, you can buy a humidifier in the air-conditioned room to adjust the indoor air environment.

Do not turn on the air conditioner in the morning and evening

In the early morning and evening every day, the indoor and outdoor temperatures are relatively low. It is recommended that vulnerable groups such as the elderly, children, and pregnant women can choose to go outdoors for appropriate exercise, breathe fresh air, sunbathe, strengthen their body's immunity, and proper sweating also has a detoxifying effect on the body. You can also use fans and baths to cool down appropriately.

Clean the filter frequently

If the air conditioner filter is not cleaned for a long time, the cooling effect will deteriorate and the air volume at the air outlet will become smaller. The most important thing is that the dust on the filter may contain a large amount of Legionella. Inhaling this bacteria into the human body may cause slight headaches and breathing discomfort. Severe cases may even lead to lung infections and pneumonia. Air conditioners that have not been used for a long time should be cleaned before being reactivated.
