The Risks of Showering

Heavy concerns about swine flu this season have led to increased germophobia world-wide. I have never been a germophobe myself, but I undoubtedly have greater concerns now that I am a new mom with an infant in daycare. As if the current fears around the spread of swine flu were not enough, we heard news earlier this week that our showerheads and shower-sprayed water contain significant amounts of bacteria. This news, of course, is disconcerting for anyone. After all, we take showers daily for the purpose of cleansing ourselves, and it is so ironic that quite the opposite could be occurring.

It is really difficult for many to not stress out about the fact that millions of bacteria are hitting your body and face as you shower, and being inhaled into your lungs. But how much of a threat are these shower germs? Scientists at the University of Colorado who conducted this specific study of showerhead microbes found that a variety of complex microbes exist in showerheads that are potentially pathogenic (i.e. can lead to disease). However, the scientists concluded that the actual health risks posed by these organisms requires further investigation, especially in individuals whose immune function is compromised.

So it appears that there is no need to stress too much about the bacteria in our showers. For those who are more concerned, you may be able to minimize the bacteria that come in contact with you by running the shower for 30 seconds prior to getting in, as the amount of bacteria appears to be highest when the shower is first turned on. Additionally, metal showerheads appear to house fewer bacteria than plastic showerheads.

We also need to remind ourselves that millions of microorganisms exist on practically all surfaces and environments that we come in contact with on a daily basis. Obviously, a majority of these germs are harmless, otherwise we would constantly be sick. Swine flu is a legitimate major concern that we do need to pay attention to and take action to prevent the spread of the virus. However, when it comes to showerhead germs, people should relax and continue enjoying their daily showers!
