Women may not be as clean as men in one part of life – pajamas.
A very unscientific survey by a British newspaper found men wear PJs on average for about two weeks before washing them. Women wait an average of 17 days.
Doctors say this could result in an infection.
"If you have a bacterial infection, that bacteria can be transmitted through your pajamas. It's very unlikely you can get an infection from your pajamas, but if your pajamas are very tight, if you have a lot of broken skin and if you have bacteria growing, that can theoretically be a problem," said Dr. Doris Day, a dermatologist.
The top excuse for not washing pajamas more often was that they are only worn for a few hours.
