How dirty is the first note rivers of the shower? The germs all hide inside the shower nozzle

After people work for one day, perhaps the first thing that came back home is to have a shower. But the majority may ignore a question, even if the shower nozzle takes numerous germs to the face in while spraying water.
U.S.A. " journal of national academy of sciences " publishes the research report to remind people on the 15th, it may initiate lung disease to use the shower nozzle.
Germ's hotbed
The researchers of U.S.A. Colorado university are in New York, 5 states such as Illinois, Colorado, field Nahsi state and North Dakota State take a sample to measure to the shower nozzle of family and public place.
They measure and find from behind 9 nearly 50 shower nozzles which cities collect, 30% of the shower nozzles hide a large number of branched bacillus of bird that can cause lung disease. This is branched bacillus of a kind of atypical tuberculosis.
Researcher to water that shower nozzle release and take down behind the shower nozzle sampling and analyzing from ink that water pipe flow out, the shower nozzle that is still unloading at the same time is chosen fetching the internal dirt to test. Through measuring DNA (DNA) of these samples ,The scientist finds that compares the hot water flowed out from shower nozzle, it is gathered in the shower nozzle that there is more bird's branched bacillus, the quantity of bird's branched bacillus is more than 100 times higher than in the running water in the shower nozzle.
The water sample of this research, except 4 come from rural family, the others stem from the urban water -supply system. Because supply water with the private pipeline, has not found bird's branched bacillus in water that the shower nozzle flow out in these 4 families, there are only some other bacteria.
Dangerous crowd
Study before to reveal, the lung caused by atypical tubercle bacillus similar to bird's branched bacillus infects the case and increases in recent years, may be instead of taking a shower and having something to do with in the bathtub with people's more and more ground showers.
Because the slight water droplet released from the shower nozzle adheres to a large number of germs, can reach people's lung depths easily.
Agence France-Presse quotes thesis main author Norman and Paes to report: "If you raise the head and meet the first note rivers flowed out from shower nozzle, this means water including branched bacillus of a large number of birds drops on your face, not very sanitary. "
"If your immune system does not have a somewhat defect, the shower is not dangerous, just with certain ill probability, " Paes adds.
However, to pregnant woman, the elderly or person struggling with disease, because the body immune system is fragile, the risk that they are initiated the lung to infect by bird's branched bacillus is much higher than common people.
Improve the measure
"This discovers that does not emphasize people should replace the shower by bathing, "Another author Laura and Bohme and Gartner speaks the thesis.
Researcher find compared with plastic shower nozzle, metal shower nozzle relatively difficult to adhere to the microorganism. Choose to have the metal shower nozzle of the filter, can reduce germs to pile up effectively.
Even so, because shower nozzles are covered with recesses and chink, it is very difficult to clean clean, even wash with antiseptic, the microorganism will " come back " soon .
After opening the shower nozzle, retreat to one minute first, can avoid a large number of germs that appear as the first note rivers is sprayed effectively.
Paes and his soap dirt and hot spring surface of water of public bath also on the plastic shower curtain of research group have found bird's branched bacillus. They sample analyzing to subway, the intersection of hospital and waiting room, office building and the intersection of tramp and the intersection of sanctuary,etc. and air of place at present.
With the enhancement of health consciousness, people pay more and more attention to with the life closely bound up health problem, such as the food security, medical treatment is ensured, medical information,etc., healthy life should be from understanding information begins!More excellent health information please enter:News channel
