Be honest: How often do you change your underwear? Do you wear the same brief the next day? Well, you are not alone.
A study conducted by market research firm Mintel revealed that one in five men wear their briefs more than once before washing them.
"There is a distinct whiff of laziness amongst men today when it comes to underwear. You might assume that for personal hygiene reasons everyone puts on clean underwear when they get dressed at the start of the day, yet only eight in ten men appear to be doing so," senior analyst Richard Caines said in a statement.
The poll also found that single men are less likely to put on fresh undies than their married counterparts.
"It seems that the influence of a partner is a positive one when it comes to changing underwear and socks, with those who are married more likely to change their underwear on a daily basis," he said.
In addition, the researchers discovered that 16 percent of men wash their clothes only when they look visibly dirty and only 19 percent of men living with their partner pull their weight when it comes to the laundry.
Lee Kynaston, Men's Health UK's online grooming editor told The Huffington Post that he wasn't surprised with the poll's results, saying, "Men are famous for the sniff 'n' wear test—fishing things out of the washing basket and donning them again if they're not classed as a Weapon of Mass Destruction."
However, unclean underwear may cause irritation to the skin because of bacterial buildup down there. Sweating, dead skin, or microbe infestation are common in areas that are not cleaned regularly, warns Dr. Pang Shiu Ming, consultant at Deparment of Dermatology in Singapore General Hospital. "When you wear unwashed underwear, the fungi present may multiply within the skin flakes," turning the skin red, flaky, warns Dr. Ming. And it usually spreads.
Worst, you might contract a urinary tract infection. This occurs when bacteria crawl their way up into the urinary tract. Changing your underwear often and washing them in hot water will kill those bacteria and prevent infections from happening, according to Live Strong.
