Since summer, the weather is very hot, indoor temperature is high and sultry. Facing this kind of weather, many people like to stay in the air-conditioned room and not come out, even enjoy the air-conditioning blowing for a day. However, it's very easy to have aches and headaches all over the body when you blow the air conditioner overnight. I don't know that the air conditioner brings us cool and refreshing, but it also has various effects on the body.
So, what's the harm of blowing air conditioner for a long time?
1. It is easy to be short of water when blowing air conditioner for a long time. In summer, people need to supplement a lot of water every day, and the biggest problem in the air conditioning room is extremely dry. If people stay in such an environment for a day, it is easy to cause water shortage of human body and skin. Because 75% of the human body belongs to water, if the water content in the body drops below 50%, it will damage the health of the body.
2. It's easy to catch cold when blowing air conditioner for a long time. Many people are afraid of blowing air conditioner for a cold, so when sleeping at night, they turn on the air conditioner and cover the thick quilt at the same time, thinking that this can prevent the occurrence of cold. However, contrary to our wishes, the respiratory tract is the most vulnerable. The quilt cover can only keep warm but not prevent diseases. When the air conditioner enters the human body from the respiratory tract, it is easy to have cold symptoms when waking up with dry mouth and nose. Therefore, try to avoid air conditioning into the respiratory tract. (this article is exclusively compiled by WYH, editor of sihai.com.

3. Long term air conditioning is easy to get headache. Blowing directly into the air conditioner, the sudden cold air stimulates the sweat pores to contract suddenly, causing people headache. Experts suggest that it is best to keep the room temperature constant at about 24 ℃, and the difference between indoor and outdoor temperature is more than 7 ℃, and often open windows for ventilation to ensure the convection of indoor and outdoor air.
4. It is easy to suffer from arthritis by blowing air conditioner for a long time. Cold air is very harmful to joints. If you don't pay attention to keeping warm, you will easily suffer from arthritis when you are old, which is difficult to treat. Experts suggest that those who work in air-conditioned rooms for a long time may as well prepare a pair of trousers in the office to protect their knees. At the same time, stand up every other period of time to improve peripheral blood circulation. (this article is exclusively compiled by WYH, editor of sihai.com.

Long term air conditioning reduces human immunity. In summer, due to the strong airtightness of the air-conditioned room, the indoor and outdoor air can not be exchanged, and harmful microorganisms such as bacteria and viruses in the indoor air are easy to breed and multiply, and the air quality is relatively low. In the long run, it is easy to reduce the body's autoimmune function, and it is also easy to be infected by bacteria and get sick. Especially people with low immunity are vulnerable to diseases.
