The editors of Factcheckers approached us at CMET with an intriguing question: Is it harmful to wear underwear more than once?

To find out, we conducted an analysis on some worn (and quite sweaty) underwear. Our findings were fascinating! The most important result was the significant differences between the samples. Participants who performed a spinning class showed up to 100 times more bacteria and even traces of faecal bacteria compared to others.

Additionally, two presenters wore their underwear for 7 days straight. The results were striking: the 7-day worn underwear had almost 20 times more bacteria compared to the start.

So, is re-wearing underwear really that bad? Not necessarily. It’s possible, but always make sure to check for smell and appearance before putting it on again.
