Research shows that frequent belts

Sleep easily causes breast cancer.

Researchers conducted a survey of more than 4700 women for two and a half years, and found that the rate of breast cancer was 21 times higher than that of people wearing shorter time for more than 12 hours a day. If people who wore them even slept, the figure would jump to 113 times.

According to the research report, the incidence of breast cancer in the United States has increased year by year, which is related to the popularity of bra.

Studies have shown that bra can oppress breasts.

The toxin produced here is not easy to discharge, and it will become cancerous over time.

Besides, most of the bra is made of chemical fiber, toxic and harmful substances in chemical fiber will also cause bad stimulation to the breast. The long-term wearing of chemical fiber brassiere is undoubtedly an important factor in promoting breast cancer.

According to this theory, it is obvious that the tighter bra is harmful to breast health.

Therefore, experts suggest that women should wear no bra or copper brassiere as much as possible, replace bra with chemical fiber products with cotton bra instead of wearing bra every day, preferably when they go out, and remove them once they get home, and massage the breasts again, so that the lymphatic system can be restored to normal.

Proper bra can protect breasts and avoid excessive drooping breast.

It plays an important role in the setting up. If the bra is not suitable, it will also bring pain to the body.

Therefore, when buying a bra, a female friend must pay attention to the appropriate size, wear not too tight or too narrow, and pay attention to the regular movement of the upper limbs, and move the sling at the shoulder position.

Do not wear a bra when sleeping. When you do not go out at home or do not greet guests, you can also consider less use, so that it can relieve or relieve its restraint on the chest.
