Diseases caused by underwear 1. Young Miss Chen came to the gynecological clinic for the third time this year. Why? It's because vaginitis is lingering. Strange to say, Miss Chen usually loves cleanliness and hygiene, and her life is very regular, but vaginitis is especially fond of patronizing her, which makes her miserable. After a detailed conversation with the doctor, Miss Chen realized that she often wore tight polyester briefs. Tight-fitting polyester briefs, wrapped around the crotch and buttocks, are a kind of fabric with poor air permeability, which makes the sweat in the perineum not evaporate, but mix with the secretions of vagina and urethra. If it is not cleaned in time, it is easy to cause perineal erosion and infection. 2. Zhang Shaofen, a woman who lives in suburban rural areas, has suffered from fungal vaginitis for many years. The doctor suspected that her vaginitis was related to underwear. She shook her head and said, how is it possible to wash underwear once every three days? The doctor asked again, do you usually iron your underwear with boiling water, or listen to what the doctor said in the sun? Some shyly said, "No.". "How can a woman's underwear hang in the sun?" Who knows, she told the reason in one sentence. Now some women are still conservative, so they are embarrassed to put their underwear in front of the door and in the sun, so they have to put it in the shade to dry. Without sunshine disinfection, it is inevitable that some bacteria and molds will breed. Wearing such underwear will inevitably lead to fungal vaginitis.
