Reasons why female breasts are prone to sagging

　   A survey polled nearly 1,400 people online female , the results show that although nearly 70% of women know that there is a sports bra, they do not use it, mainly because they feel it is not necessary. Among women who have the habit of wearing sports bras, 70% said that they choose this type of bra mainly to reduce the degree of breast shaking, and nearly 50% of them choose this type of bra to avoid loosening of the breasts due to exercise.

　　The breasts will vibrate and sway when doing sports such as running and jumping. If you don't wear a sports bra, your breasts will swing involuntarily, causing permanent damage to the elastic fiber tissue in the breasts, leading to sagging breasts. A British survey also showed that when an average person runs for one mile, their breasts will move 135 meters.

　　Wong Can-hung, president of the Hong Kong Association of Occupational Physiotherapists, said that among the patients he came into contact with, some even strained soft tissues and pectoralis major muscles and even had difficulty breathing because they did not use sports bras for exercise. When women feel chest pain, some people will first think of breast disease or orthopedic problems. Few people realize that strenuous exercise may cause breast damage.
