Luan Jie, director of the Breast Plastic Surgery Center of the Plastic Surgery Hospital of China Academy of Medical Sciences, said that the bra, except as a decoration, has no influence on the development of breasts and has no other health care or treatment functions. Modern medical research has confirmed that wearing a bra will not bring any benefits to breast health. If the bra is not properly worn, it will bring some health problems, especially the common gathered bra on the market now, which is easy to oppress the breast.

"There is a certain correlation between breast ptosis and breast size. Generally speaking, large breasts are a prerequisite for breast sagging, while people with small breasts are generally not prone to sagging, "Luan Jie said.

Breast ptosis is irreversible, and wearing a bra does have a certain relieving effect on breast ptosis. Huang Rongrong, deputy chief physician of the General Surgery Department of the Air Force General Hospital, said that generally speaking, due to gravity, the breasts are prone to sag, which will affect the blood return in the chest, and the blood flow will easily stagnate in the chest, thus affecting the development of the breasts. Wearing a bra can overcome the influence of gravity on breasts.

Luan Jie said that for people with big breasts, wearing a bra can't prevent sagging breasts. Wearing a bra may relieve breast sagging in a short time, but when the breast grows to a certain extent, wearing a bra can't prevent breast sagging.
