Believe in your side, there are always people like this:
After washing the public toilet, wash your hands carefully with hand sanitizer. Wash your hands and then dry them with a dryer. Think of this as a way to 'sterilize'!
However, these commonly used 'sterilization' washing methods can really keep people away from germs? I am afraid you will be disappointed... Hand sanitizer in public areas: Bacteria exceed the standard hundreds of times!
In some public places, hand sanitizer is provided in the bathroom, but do you know that the hand sanitizer is not as effective as the fungicide we imagined? On the contrary, in some places, the hand sanitizer has become a hotbed of bacteria.
CCTV reporters have sampled the toilets in many shopping malls and restaurants in Beijing. The results showed that the hand soap in some public places has a very low bacterial content.
The highest number of bacterial colonies is as high as 2,300 CFU per gram (the number of bacterial colonies). Experts say that the hand sanitizers in these public places have become 'bacterial medium'!
Similarly, the media in other cities have conducted relevant investigations and tests, and found that the bacteria in the hand sanitizers in many public places exceeded 10,000 times!
In 2013, Li Tao, deputy director of the Environmental Protection Center of the Chinese Center for Disease Control and Prevention, said in an interview with CCTV reporters that if you wash your hands with such a dirty hand sanitizer, it would cause a purulent infection on the wound on your hand; if there are more bacteria, the wound on the hand Larger, it will enter the blood directly, especially if P. aeruginosa and S. aureus enter the blood, it will produce sepsis, bacteremia, bacteremia, etc., if it is bad, it can cause other diseases, even life-threatening.
Dryer:
The more you blow, the dirtier!
In addition to hand sanitizer in public toilets, dryers are also commonly used as a good substitute for saving paper protection resources, but whether it is clean and healthy, in fact, there are controversies a few years ago.
Foreign researchers did a test, put a clean chassis into a dryer in the public restroom, put it in for three minutes, and then do bacterial culture, in just a few days (there are reports that it is 48 hours) These things are growing wildly:
There are so many bacteria hidden in the dryer! After using the dryer, a variety of pathogenic bacteria and fungi will stick to your hands, many of which are large amounts of bacteria in the feces, which are very prone to disease.
These dryers contain Klebsiella, which may cause fever, nausea, vomiting; Enterobacter cloacae may cause serious respiratory infections.
They even found Staphylococcus aureus in a bathroom dryer. The pathogen may cause severe staphylococcal infection. If there is a wound on the hand and the dryer is used, it is very likely to cause serious skin infection.
Every day, countless people come in and out of these bathrooms. Maybe everyone didn't think that they thought we could keep the clean dryer, but it became the culprit.
The Journal of Applied Microbiology published a study in early 2016. Some people specifically compared paper towels in public restrooms, heater dryers and jet dryers (which are purely wind-dried). Which one is more sanitary? some.
It turned out that paper towels are the cleanest!
The pure wind dryer not only hides bacteria, but also spreads bacteria in large quantities. It spreads 1300 times more bacteria than paper towels, and the bacteria are blown away by the wind to within 10 feet of the dryer!
Disposable hand sanitizer:
It is better to wash your hands!
Someone asked: 'Then I can't use the disposable hand sanitizer?'
The hand sanitizer contains bactericidal (alcohol-based) and skin care ingredients, but the disinfectant is often irritating, although it contains skin care ingredients, it may cause skin allergic reactions; and this quick-drying disposable hand sanitizer Flammable, keep away from open flames, and can't be handed over to children alone, very unsafe.
In addition, there are so many chemical preparations in this hand sanitizer. After washing this hand, take the food and eat it. It is not directly eating the chemical into the stomach!
Therefore, in daily life, it is not recommended to use disposable hand sanitizer instead of hand washing.
Correct hand washing method
Wash your hands, preferably under the tap, rinse with running water, preferably with soap, then dry with a clean paper towel;
If there is no soap, then rinse it with water only. It is best to rush for 40~60 seconds. If the time is too short, the bacteria will easily remain on the hands and become a hotbed for spreading the virus. After washing, wipe it with a clean paper towel!
