Underwear can help women shape their breasts. In fact, in addition to these benefits, underwear may also cause 7 harms to the breasts.

1. The cup is too small and the muscles overflow

There is a theory about bra cup size: it is better to be too big than too small, and it is better to be loose than tight! This shows that it is very dangerous if the cup size is too small, because it will compress the breasts and cause poor lymphatic flow, which can easily lead to breast disease. In addition, a cup that is too small will cause muscles to overflow and cause accessory breasts, which not only affects health but also affects appearance.

2. The cup size is too large, causing breast deformation

Although a cup that is too large will not have a great impact on health, it is not conducive to women's shaping of breast curves. When choosing a bra, it is generally recommended for women to choose one or two bras that are one size larger than themselves. This can be done during the menstrual period. Wear it regularly. If it is too large, it is easy for the breasts to sag and become deformed.

3. The bra straps are too tight and compress the breasts

Tight shoulder straps will not only cause shoulder discomfort, but also cause the bra to move upward. The bottom of the current bra is fixed with steel brackets. Therefore, if the bra moves upward, the harder steel brackets will compress the breast tissue. If a girl's bra moves up during exercise, she must adjust her bra in time.

4. The bra is too tight, causing excess fat

Don’t think that the tighter the bra, the better the shaping effect. A bra that is too tight will cause poor blood circulation, chest tightness and air pressure, and will also allow annoying fat to creep in! The correct tightness should be that the shoulder straps, straps, and cups fit comfortably against the skin without tightening the muscles. The bottom of the bra should be at the same height from front to back.

5. If worn for more than 12 hours, the induction rate of breast cancer can reach 75%

In addition to what is mentioned above, if you wear it for more than 12 hours a day, the risk of breast cancer can reach 75%. Therefore, if you can try not to wear a bra at home or in non-public places, this will be beneficial to preventing breast cancer. The Shanghai Gynecological Diseases Rehabilitation Committee has released a latest survey, which shows that 79.3% of women in the city do not wear bras appropriately. The main symptoms are: wearing it for a long time, being too tight and not adjusting it. Clinical statistics also found that those who wear a bra for more than 10 hours a day are prone to breast disease, and the risk is twice that of other people. In addition, improper bra wearing may cause the following health problems.

6. Improper bra wearing affects lymphatic reflux

Many women shift their breasts from outside to inside when wearing them. As a result, the breasts look tall and beautiful, but they affect lymphatic flow, delay metabolism, increase toxins in breast acini, and increase the chance of illness.

7. Improper wearing of bras can cause insufficient blood supply to the breasts

"Improper bras can cause breast pain: If a bra that is too tight is used for a long time, poor blood supply and fibrosis will occur in the pressed area under the breast, and cord-like hypertrophy will form, which will be painful when pressed." Beijing Millennium Monument The director of the hospital summarized the harmful effects of improper bra wearing in simple words.
