The science behind bras
There is actually no scientific evidence to suggest that if you wear a correctly fitting bra, there are no negative effects on a woman’s health.
If the bra however is not properly fitted, it may lead to pain in the neck area and in the chest muscle area. Even very tight shoulder straps can cause some discomfort in the shoulders as the straps are one of the main support for the breasts, the tension may lead to a permanent groove in the shoulder tissue.
On the issue of breast sagging, for people with fuller breasts, supporting the connective tissue of the breasts by wearing a right fit bra may help reduce the rate of sagging.
