First, the sports bra is a special underwear for women to protect their breasts when doing various fitness exercises. It has the functions of vibration prevention and sweat absorption. Any high-intensity exercise will have an impact on women's chest, so wear a sports bra to fix the chest from impact.

Second, wearing a sports bra can avoid the obstruction of the chest to sports. Because people always sweat when exercising, another function of sports bra is to absorb sweat, ventilate, dehumidify and deodorize, and sports bra is generally elastic, which is convenient for limbs to stretch freely.

Third, if the body perspires poorly, it will cause skin inflammation. Therefore, the sports bra makes the breast and body form as a whole, and strongly supports the movement through the model design and the whole chest binding. In addition, the fabric of sports bra is generally cotton, which is elastic and suitable for perspiration, warmth and limb stretching.

Extended data:

Sports bra is best not to wear it to sleep, because sports bra is a kind of underwear that can be worn in public places and can show the wearer's energetic personality. Therefore, it is best to wear it only during exercise, not in other non-sports occasions.

Sports bras are comfortable to wear, but sports bras can't be worn often. Wearing a sports bra for a long time is not good for people's chest health. The fixation of sports bra on the chest is worse than ordinary underwear. Tightening the chest too tightly for a long time will affect the blood circulation of the chest and lead to sagging and sagging of the chest.
