Dryers suck in and spray harmful bacteria.
A group of microbiologists from the University of Connecticut in the April issue of Applied and Environmental Microbiology published the results of a study on Deposition of Bacteria and Bacterial Spores by Bathroom Hot-Air Hand Dryers in hand dryers.
The devices turned out to suck in germs and dangerous pathogens thrown into the air after flushing the toilet bowl, and then bombard newly washed hands with them. The use of filters in dryers can reduce the number of harmful microorganisms, but it will still not be possible to completely solve the problem in this way.
Research progress
Some of the Petri dishes were simply left in the washrooms for two minutes, the other part was placed under the hot air of dryers for 30 seconds, and then the bacteria colonies formed were counted. It turned out that the largest number of colonies, namely from 18 to 60, appeared in the dishes left under the air from the dryers. Less than one colony was found on the cups that were just in the toilet.
The study also noted that using antibacterial filters in dryers reduces the total number of germs by about four times, but still does not completely eliminate them.
Hand dryers suck in harmful bacteria and attack you with them.
results
Most often, spores of the hay bacillus Bacillus subtilis, a species of bacteria that are harmless to humans, were found in Petri dishes. However, other microorganisms were also present, causing dangerous diseases. These include Staphylococcus aureus, clostridia, which are the causes of skin diseases, pneumonia, meningitis and sepsis.
What to do if you don't want to get infected
It is safer and more hygienic to use paper towels than hand dryers. They are more effective at removing residual water, and during friction, bacteria are transferred to the paper. By the way, in the university where the study was conducted, dispensers for paper towels were supplied after receiving the results.
