What’s in your showerhead? We’re so glad you asked! Your showerhead might just be harboring bacteria, then blasting it onto your body, and possibly even into your lungs.
A study carried out at the University of Colorado in 2009 by Dr. Norman Pace, a professor of molecular, cellular, and developmental biology, studied how the microorganisms that can cause pulmonary (lung) disease can accumulate in the showerhead. His research showed that while these microbes may be present at levels of 0.1-1% in the water coming into the shower, it may make up to 70-80% of the biofilm in the showerhead itself.
In a 2009 interview, Dr. Pace suggested that breathing in this particular bacteria could cause a “low-grade cough that persists for months,” making you feel “lousy, weak,” and leading to, perhaps, “breathing difficulties.”
So, as you take stock this time of year, you may want to stock up on cleaners for your bathroom, or at least a new showerhead.
