Is It Okay to Wear the Same Underwear Twice? Here’s Why You Might Regret It
We’ve all done it — laundry’s not done, you’re in a rush, and yesterday’s underwear seems “not that bad.” But wearing the same pair two days in a row can have more consequences than you’d expect.
Underwear sits against warm, moisture-prone skin, collecting sweat, oils, and bacteria. Rewearing it presses all that right back onto your body, increasing the risk of:
-
Bacterial infections (like UTIs, BV, and jock itch)
-
Yeast overgrowth
-
Skin irritation, chafing, and rashes
-
Odor
-
Butt acne
Women are more prone to infections, while men are more likely to experience odor and irritation. Fabric matters too—cotton is breathable, while synthetics trap moisture. If you must rewear, choose clean, dry cotton and avoid anything crumpled or damp.
Pro tip: skip underwear at night to let skin breathe, and always change after workouts.
Bottom line? A clean pair each day is one of the easiest ways to support hygiene, comfort, and skin health. Just change them. You’ll feel better—and smell better too.
