Science says no more bras!
Jean-Denis Rouillon, a sports medicine professor from Centre Hospitalier Universitaire de Besancon in France, took on the weighty task of studying the effects of bras on women's breasts. After 15 years, he found that the garments do nothing to prevent breasts from sagging — and may even increase it.
"Our first results confirm the hypothesis that the bra is a false need," Rouillon said, according to France Info.
"Medically, physiologically, anatomically, the breast does not benefit from being deprived of gravity. Instead, it languishes with a bra."
Wearing a bra inhibits the growth of breast tissue and contributes to poor posture and muscle tone, he said, adding that "the breast will gradually degrade."
