Student wears unwashed jeans for 15 straight months

A Canadian student tested the limits of personal hygiene by wearing the same unwashed jeans for over 15 months.

While this may not be ideal for most people, it surprisingly was discovered to cause no health risks for healthy people.

Josh Le, a student at the University of Alberta, was so excited when he bought a pair of Nudie Jeans in September 2009 that he wore them every day. He even went so far as to sleep in them for a month, according to the National Post .

Nudie Jeans are raw jeans that are specifically designed to shape itself to the contours of the individual's body. Raw denim isn't chemically treated or washed prior during manufacturing. It is sold to the consumer stiff like cardboard. The idea is that wearing the jeans without washing them will result in the indigo color wearing away at pressure points in the fabric, showing the individual's body contours. When the jeans are eventually washed, the individual's shape will be revealed in the pattern that develops, according to The Star .

After wearing his raw denim for 15 months and one week, Le went to a professor of textile science at the University of Alberta, Rachel McQueen. She assisted him with an informal experiment. They took bacterial swabs from different areas of the jeans, including the front, back and crotch area.

"I expected to find some bacteria associated with the lower intestine such as E. coli, but was surprised to find there weren't any, just lots of normal skin bacteria," McQueen told the University student newspaper site . McQueen carries out research in the development of odour and its relationship to bacteria in textiles.

She had been expecting to find harmful bacteria, such as E. coli, in the crotch area, but there were only non-harmful, skin bacteria colonies. She did warn, however, that it was just one unpublished study on a single pair of jeans, and it may not be true for all cases.

Raw denim is growing in popularity, with other teenagers wearing the jeans for six-month stretches to get an individual look.
