After a day's work, the first thing people do when they get home may be to take a shower. But most people may overlook a problem, that is, the shower head will bring many germs to the face while spraying water. The research report published in the Proceedings of the National Academy of Sciences on September 15, 2009 reminds people that using shower heads may lead to lung diseases.
Laura baumgartner, another author of this paper, said: "The findings of this study do not emphasize that people should take a bath instead of a shower. The researchers found that compared with plastic shower heads, metal shower heads are more difficult to attach microorganisms. Choosing a metal nozzle with a filtering device can effectively reduce the accumulation of germs. Nevertheless, because the shower nozzle is full of hidden places and gaps, it is difficult to clean it, even if it is cleaned with disinfectant, microorganisms will soon "make a comeback". After turning on the shower nozzle, retreat to the outside of the bathroom for one minute, which can effectively avoid a large number of germs sprayed by the first water injection. Pace and his team also found Mycobacterium avium in soap scales on plastic shower curtains and hot spring baths. They are sampling and analyzing the air in subways, hospital waiting rooms, office buildings and homeless shelters.
