A whopping 22 percent of man confess that they do not change their undies every day, and women did not fare much better with 18 percent admitting to re-wearing their knickers.
Shockingly, one in 20 gents confessed to re-wearing their bills more than five times before they were cleaned, which is seven percent for women.
In order to find out about their grooming habits, the research by OnBuy surveyed 2,790 men and women and the findings make for fascinating reading.
Of those who admitted not changing their underwear every day, 76% said they turn them inside out for a ‘cleaner feel’ for men and 69% for women.
The survey also found that for more than three years, 13 percent of men and four percent of women keep their old underpants to try to get their money’s worth, while 40 percent of men to 55 percent of women substitute them annually.
Speaking to the Metro about the possible risks of not changing your pants on a daily basis and washing them between wears, Natura Emporium ‘s skincare specialist Dr Nichola Cosgrove explained: “Underwear in a way acts as a barrier to protect our clothes, as it’s easier to wash our underwear regularly then our clothes.
“By not changing your underwear every day you will start to have an accumulation of bacteria like Escherichia coli, staphylococcus, streptococcus and many others that are perfectly normal and useful when they remain at their required levels.
“However, because they thrive in a warm and humid environment, they will start to multiply out of control. The effects of these can be as simple as a bad odour, a rash, excess itching, to full on yeast infections, urinary tract infections and potentially life-threatening staph infections.”
