The honest guidance is to wear fresh underwear daily rather than repeating the same pair across days. Underwear sits against skin in a warm area and collects moisture and bacteria through normal wear, so changing daily is simply a basic hygiene habit. Wearing the same pair two days in a row isn't an emergency, but it's not ideal, and breathability and comfort suffer.

If you sweat a lot, exercise, or it's hot, changing more than once a day can feel better. The practical fix is owning enough pairs that you never feel pressed to repeat one — and choosing breathable fabric, which keeps things drier and more comfortable through the day. So: change daily, keep enough on hand, and favor breathable material. Any persistent irritation or discomfort is worth raising with a professional. More in is cotton underwear better.
