Women have long been told that a good bra can help support the chest, relieve back pain and prevent sagging. However, a new 15-year French study reveals the opposite: bras do little to reduce back pain and, over time, they can actually make breasts sag even more. Researcher Prof. Jean-Denis Rouillon, a sports science expert from the University of Besançon in eastern France claims that “bras are a false necessity.” “Medically, physiologically, anatomically – breasts gain no benefit from being denied gravity,” said Rouillon. “On the contrary, they get saggier with a bra.” Rouillon and his team spent years measuring the changes in the breasts of 330 women using a simple slide rule and caliper at the Centre Hospitalier Universitaire (University Hospital) in Besançon, where he carried out his research. He found that no evidence that bras helped ease back pain. Instead, he found that the chest supports could even add to the problem.
