A growing number of public toilets, instead of paper towels, offer traditional or super-fast hand dryers that promise full effect in 10 seconds. However, these miracle devices have significant drawbacks that are associated not only with
dryness later.
Recently, a resident of California Nicole Ward, who works in the laboratory, decided to check one of the dryers for the presence of harmful bacteria in it. What will be the results and whether
hand dryer They have a lot of disadvantages, or it’s just a myth.
"Site".
Electric hand dryer Nicole Ward checked for the presence of bacteria one of the modern hand dryers in the public toilet and published the result on his page in the social network. Turns out there's a lot of them. This is not surprising, because bacteria are everywhere, and this is normal.
An American woman shows a petri dish and what grew in it a few days after she put it under the dryer of one of the common brands for only 3 minutes. She said: “It’s a few strains of possible pathogenic fungi and bacteria that cause many diseases that end up on your hands when you’re sure your hands are clean.”
The bad news is that pathogenic fungi are transferred to our hands every time we dry them. But more often, they begin to develop as a result of the fact that people do not dry their hands completely and moisture remains on them. And some researchers say that the powerful flow of hot air works for the benefit of the spread of microbes.
Nicole also stressed that she does not scare anyone, but only wants to demonstrate to subscribers that pathogens can lie in wait literally everywhere. In turn, the manufacturer of powerful hand dryers, Dyson, conducted a study with the participation of scientists from Queen Mary University in London, which proved that dryers are just as effective in killing bacteria as towels.
One thing we can say for sure is that hand dryers strongly overdry the skin, and in order to avoid itching and tightness, you should always apply moisturizers to your hands or switch to paper towels (napkins), or use an antibacterial gel. And, of course, it is better for small children not to use such dryers, because their skin is very tender.
