The main advantage of dryers is no need for paper towels or replacement. Because of this advantage is possible to save a considerable amount, moreover, it is said to be beneficial in terms of sustainability. Recently, however, scientists have discovered a big minus dryers: it turned out, they contribute to the spread of microorganisms, according to Science World Report.
To confirm their assumptions specialists conducted an experiment. They are applied to the hands completely harmless lactic acid bacteria, which in public toilets are generally not encountered. Then the experimenters deliberately poorly washed hands and dried them with a dryer.
The ensuing investigation led to the discovery of air in them, lactic acid bacteria. This gives scientists suggest that during the drying air enters at the hands of all present microorganisms. As further analyzes by the use of high-speed molly maid dryer the amount of bacteria in the air is almost five times more than when used with warm air dryer. When using paper towels number of microbes in the air has 27 times less.
It is also noteworthy that the bacteria present in the air, not only during the drying process, which lasted only 15 seconds, but after that, and quite a long time. Seven minutes later half of lactic acid bacteria is still "hovering" in the air space of the toilet.
Based on these data, scientists argue that the dryer has a negative impact on human health and may contribute to the rapid spread of infections. Specialists insist on the need to take into account these data during the design of public toilets, especially when it comes to toilets in health care facilities
