You should replace your underwear every day to maintain proper hygiene because underwear absorbs oils, sweat, and bacteria from the skin, which can lead to infections and skin irritation if not changed regularly. Wearing clean underwear helps reduce the risk of urinary tract infections, fungal infections, rashes, and unpleasant odors caused by bacteria buildup. Additionally, old or worn-out underwear loses softness and elasticity, which can cause chafing and discomfort, especially in sensitive areas. Changing underwear daily also helps keep the area fresh and prevents skin problems caused by moisture and bacteria accumulation.
