Changing your underwear every day isn’t just about feeling fresh. It’s a basic health habit many people quietly skip, and doctors say that can cause real problems.
Underwear traps sweat, bacteria, and microscopic waste in one of the warmest areas of the body. Wearing the same pair longer than a day allows bacteria and fungi to multiply, increasing the risk of irritation, odor, and infections. Even if underwear looks or smells fine, harmful microbes can still be present.
Health experts warn that prolonged wear raises the risk of yeast infections, bacterial imbalances, and fungal rashes like jock itch. Tight or synthetic fabrics, exercise, and hot climates make the problem worse by locking in moisture.
The fix is simple: wear clean underwear daily—and change again after sweating. It’s one of the easiest ways to protect skin health and avoid preventable infections.
