Scientists have found that taking a shower might not be so good for you. New research from the University of Colorado has found there can be a build-up of harmful bacteria in showerheads. Researchers said the very first jets of water from the shower are the most dangerous. The shower acts like an aerosol（喷雾器）, spraying the bacteria into the air. This means having a daily shower may not be as hygienic as we think. Scientists tested 50 different showers across nine US cities. They discovered that a third of these had very high levels of bacteria that can cause lung damage. Researcher Laura Baumgartner advised: “For most people, the answer is simple. Don’t stand in front of the shower when the first blast comes out."
The research is part of a wider project that is looking at our daily environment. In particular, the research team is looking at the microbiology of water and air in schools, homes and public buildings. Research into the bathroom environment provided interesting results. Ms. Baumgartner said showers were more dangerous than baths because they act like aerosol sprays. Showerheads are much harder to clean than baths because they are enclosed. Furthermore, it is easier for us to inhale the bacteria into our lungs because of the steam in the shower. Baumgartner did say we should not be too concerned about her discovery: "I take showers every day, and I’m not at all worried," she said.
