In hot weather, I like to blow my body with a fan. What are the disadvantages of doing so?

It's hot in summer, and the temperature rises gradually. In order to resist the heat, in addition to turning on the air conditioner, many people will always turn on the fan to blow away the hot air and make people feel cool. However, it is not a correct choice to keep blowing fans at the body, which is harmful to people's health.

Some people will turn on the fan to the highest speed in order to cool down for a short time. Indeed, the wind is very enjoyable, but when the temperature reaches 30 degrees, it is comparable to the temperature of the human body from the body surface. At this time, the fan blows the same wind. The human body excretes heat through sweat, but when the fan blows, the body surface temperature will drop, and the sweat will not flow out because of poor pores, resulting in general weakness, backache and backache.

Others like to blow the fan for a long time, which is also inappropriate. If it is blown for a long time, it will cause a series of problems to the body. Your body temperature keeps dropping during blowing, which is particularly easy to cause colds, diarrhea and abdominal pain. It is not a pleasant thing to have a cold and a runny nose on a hot day. Be sure to pay attention to the duration of blowing the fan.

Blowing directly at the fan can also cause disease, and blowing the fan is the most likely to aggravate scapulohumeral periarthritis. Some workers who sit in the office for a long time will have a small fan at hand if there is no air conditioning indoors, and then blow it often. Because of long working hours, most of them have cervical spondylosis and scapulohumeral periarthritis. If they are always blown by the cold wind, it is easy to cause shoulder pain and the spine will be tense and numb, so be sure to pay attention.

Blowing fans can cause many diseases, in addition to these, there are some minor problems, such as body fluid secretion and endocrine disorders, or reduce the quality of sleep. What's more, it will increase people's cardiovascular and cerebrovascular burden and so on.
