The day the shower sprayed germs on you

The shower is a tool to cleanse the body, but the surprise is that they are also full of germs and bacteria.

Scientists in the United States are lobbying to contribute bacteria samples from all over the country to make a list of the prevalence of different types of bacteria across the country.

E.coli bacteria are also available on the shower.

"We are interested in the environment in every home," said Noah Fierer, a biologist at the University of Colorado. In the past few years, researchers have turned to understanding the right bacteria in the gut, on the skin surface and around the environment.

The reason is because people often worry about bacteria other than nature but pay less attention to germs living in the house and whether they have a bad effect on health.

They found that the proportion of bacteria depends on the climate, the ratio of men and women, the number of domestic animals. Most are harmless, while small proportions of allergens and pathogens play a role in developing the immune system.

Especially the ecological environment on the shower turned out to be very rich, because this is a place where micro-conditions are quite special. Notably, a group of scientists from the University of North Carolina, the National Institute of Respiratory Medicine found atypical tuberculosis Nontuberculous mycobacteria capable of causing lung infections.

More strangely, the level of infection in the cities is very different, and many places have exploded into epidemics like Hawaii.

People often worry less about the bacteria that live on familiar household items.

Through observation, the research team believes that a harmless or beneficial bacterium that can harm this individual may harm another individual. They did not understand the mechanism of this phenomenon, and wanted to extend sampling to all of Europe for analysis next fall before the official conclusion.

Even if there is a result, it takes more time to have a thorough prevention solution. Meanwhile, Frirer stressed that there is basically nothing to worry about.

"Now the only thing that needs to be done is to get used to the fact that we are bathing with a microbe," the study published by The Royal Society.
