First of all, don't wear a bra for too long, no more than 8 hours a day, and you can't sleep with it. When you are free, you can do more chest expansion exercises or lift your upper limbs to promote blood circulation. Second, choose cotton. Chemical fiber bra is easy to induce skin allergy and has poor air permeability. When people are active, the bra will constantly rub the nipple, and the fiber filaments in the bra can easily enter the breast from the breast hole. Over time, it will block the breasts and nipples and induce breast diseases. Third, choose a loose bra, preferably one size larger than your own breasts. Wearing a bra that is too small and too tight for a long time will affect local blood and lymphatic circulation and induce various breast diseases.
First of all, girls must wear sexy underwear in adolescence, otherwise it will lead to breast or ligament damage, hunchback or even hypoplasia.
Second, girls need the support of bust when they are developing. Girls have high breast fat content and no muscle tissue. Therefore, when girls develop, the mammary glands can't bear the pressure, which will also hinder the blood circulation. Therefore, it is easy to accumulate blood, leading to breast diseases, and the breasts are more likely to be injured during exercise. If the breast is injured, the girl may suffer from mastitis. Some girls are embarrassed to wear sexy underwear, which will lead to their hunchback and affect their future study and work.
Third, the role of girls' underwear is to maintain healthy development and vitality, and to shape a good figure and perfect curve in the future.
