Wearing a sports bra while running is vital for maintaining breast health and ensuring comfort. Running causes breasts to move in a repetitive bouncing motion, which can lead to discomfort, pain, and potential tissue damage over time. Sports bras are engineered to reduce this movement, offering support and distributing impact evenly. Proper support also prevents ligaments and skin from stretching, which can cause sagging. Moreover, sports bras wick away moisture and reduce friction, helping avoid chafing. For female runners, a well-fitted sports bra is as essential as good running shoes to optimize performance and safeguard health.
