Keep Your Showerhead Clean to Avoid Bacteria

Keep your showerhead clean to avoid bacteria. Specifically, Mycobacterium avium, which has been linked to lung disease in some people.

University of Colorado researchers tested 45 showers in five states as part of a larger study of the microbiology of air and water in homes, schools and public buildings. The study finds showerheads are home to tiny bacteria that spray into your face as you wash.

In answer to the question of whether or not showers are dangerous, lead author Norman R. Pace said, “Probably not, if your immune system is not compromised in some way. But it’s like anything else, there is a risk associated with it.”  

The researchers suggested all-metal showerheads which microbes have a harder time clinging to. Still, the researchers said showerheads are full of nooks and crannies making them hard to clean. The microbes come back even after bleach treatments.

Laura Baumgartner, co author of the study, which is found in todays edition of Proceedings of the National Academy of Sciences, noted if you who have filtered showerheads the filter could be replaced weekly.

If you have a compromised immune system and cannot keep your showerhead clean, I suggest a bath.
