It may sound like the most basic hygiene rule, but changing underwear every day is one habit many people are quietly skipping. Now, experts warn that dirty drawers arenโt just gross โ what lingers behind can carry real health risks, making daily changes a non-negotiable practice.
As unsettling as it sounds, a 2021 study found that a typical pair of underwear contains roughly 0.1 grams of fecal residue. With that in mind, going more than a day without swapping for a clean pair isnโt just unpleasant โ it could carry real health consequences, according to medical experts.

Yet despite clear hygiene guidelines, a large portion of young adults arenโt sticking to daily underwear changes. A 2023 Newsweek poll revealed that 36% of Gen Z respondents โ those aged 18 to 24 โ admit to wearing the same pair of underwear for over 24 hours, and an additional 14% say they do this regularly. That means half of Gen Z reported going at least one full day or more in the same undergarments.
But the behavior isnโt limited to the youngest age group. The survey also found that 24% of millennials โ those aged 25 to 34 โ regularly wear the same pair of underwear more than once.
