< p > the temperature will drop again. I believe that many middle-aged and old people have already worn < a href= "//m.pmae.cn/news/index_f.asp" > warm underwear "/a" in order to protect the cold, but some people are not suitable for wearing thermal underwear.

Yesterday afternoon, the doctor of Department of Dermatology of City Hospital of traditional Chinese medicine told reporters that every winter there are some elderly people who come to the hospital for itching because of skin itching. Many of them are caused by wearing thermal underwear.

The doctor warned that the elderly with dry skin had better not wear thermal underwear. The traditional < a href= "//m.pmae.cn/news/index_f.asp > pure cotton underwear < /a > is the safest for the human body.

< p > "the air permeability of thermal underwear is too poor, and the skin needs to breathe."

Hu Hanfeng, a department of Dermatology doctor at the Municipal Hospital of traditional Chinese medicine, said he himself wore warm underwear, but he was no longer comfortable after wearing it. During his daily visit, there were always some elderly people who had skin itching symptoms during cold winter, or the elderly with eczema aggravated their condition to the hospital.

< p > because thermal underwear is made of composite sandwich material, some of which are sandwiched with a fluffy chemical fiber or film in two layers of ordinary cotton fabric, which can resist heat by exchanging heat between the skin and the outside.

Although it has the effect of keeping warm, it has lost its air permeability.

Under such circumstances, two kinds of people are not suitable for wearing thermal underwear. One is those who love sweating. < a href= "//m.pmae.cn/news/index_f.asp" > warm underwear < /a > is not conducive to sweat discharge, and is easy to catch cold.

The second is the dry skin of the people, the original skin is not a lot of moisture, coupled with the plastic film and thermal insulation of the warm underwear friction easy to accumulate static electricity, these static electricity around the human body can generate a lot of cations, so that the moisture content of the skin decreases, and dandruff increases, so those who own skin dry and sweat less, the longer the skin wearing dry underwear, the longer the skin dry, and over time, even induce skin itching, causing contact dermatitis, eczema and other diseases.
