Bacteria cling to the body like glue

Bacteria can live for weeks or even months on your clothes, according to Philip Tierno, MD, director of Microbiology and Immunology at New York University. Tierno adds, that even brand-new clothes can still be contaminated with germs, so it’s definitely a good idea to take off the shirt you’ve been walking around for 12 hours in, before sitting on the bed. This rule should apply to your guests as well.

Wearing your outside clothes on your bed can cause infections, rashes, acne, and even bring in fleas.

One of the reasons we often see acne on our back and chest is due to greasy clothes, which gather street and office dust, sweat, and dead skin — in general, the human body sheds approximately half a million skin cells and about a liter of sweat daily. And your bed can be a great transportation hub for all that dirt.
