True or false? Not wearing a bra causes sagging breasts
Most women are familiar with bras — a common undergarment used to support and cover the breasts. But there’s a common question: “Does not wearing a bra cause sagging breasts?” A long-term study of women’s breasts over 15 years suggests that the cause of breast sagging is not yet definitively linked to bra usage.
In fact, sagging can be influenced by many different factors :
- Age : As we get older, collagen and elastin — the proteins that support skin elasticity — decrease, causing the skin and chest muscles to weaken and the breasts to sag under gravity.
- Multiple pregnancies : During pregnancy, hormonal changes enlarge the breasts in preparation for breastfeeding. Once nursing ends, the breast size rapidly decreases, leading to loss of firmness.

- Large breast size : Heavier breasts put more strain on the ligaments and skin, which increases the likelihood of sagging compared to smaller breasts.
- Sudden weight gain or loss : Rapid body changes cause the skin to stretch or shrink quickly, often resulting in a loss of skin firmness and breast shape.

- Estrogen deficiency : Estrogen plays a role in maintaining skin and tissue elasticity. Low estrogen levels due to age, menopause, or health conditions may accelerate sagging.
- Smoking : Toxins in cigarettes break down collagen and restrict blood flow to the skin, accelerating skin aging and causing breasts to sag earlier than in non-smokers.
According to Jean-Denis Rouillon, a French sports science expert who studied the breasts of hundreds of women over 15 years, bras do not prevent sagging due to gravity — and in some cases, they may even weaken the chest muscles that support the breasts naturally. The main purpose of a bra, therefore, is to enhance shape and appearance, not to prevent sagging.
