The bra’s primary purpose is to support the weight and structure of the breast. However, many women often have a lot of tightness and stiffness localized where the bra strap is placed. Tight-fitting bras can also harshly distress the ribcage, as well as cause back and neck pain.
If bra straps are loose-fitting and the back strap is skin-tight, it may result in an imbalance.
As for sports bras, they can often give a little too much support and prevent the ribcage from functioning appropriately, therefore weakening back muscles and overstressing the breast ligaments.
However, if you do standard exercise it’s vital to have some support or else you risk injuring the internal composition of the breast.
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.
