Among the benefits of washing hands, the risk of influenza is reduced, effective in preventing conditions such as diarrhea, protection of certain diseases by touching the clean hands of the eyes, ears and nose during the day, preventing fatal respiratory diseases such as pneumonia, preventing infant deaths, After 5 years of age with the habit of hand washing with the appropriate hand washing, even if small in size growth is effective.
UNICEF emphasizes that handwashing before, after, and after a toilet is more effective than a vaccine or doctor intervention.
Pneumonia , the most dangerous of respiratory diseases, is one of the biggest causes of child deaths under 5 years worldwide. It is responsible for nearly 2 million deaths per year. If we add Diarrhea next to it, they are the causes of the deaths of nearly 4 million babies and children together . It is the parents' responsibility to teach children the correct handwashing techniques against handwashing.
However, when vaccinating this to the child, he / she should behave consciously and should be told that it should be washed at home and school, before, after, after and after the toilet and after play. otherwise it should not be misunderstood by the child and turned into a psychological state that will become an obsession in the future.

What is used in hand washing?
Some people say I just wash it with water . They say water cleans everything but it really is in the case of cannons. In other words, since we do not open the cannons, water alone is not enough for cleaning.
Soaps and detergents disrupt the structure of bacteria collected in the hands . You should never get the idea that there is no hundred percent bacteria left in the hands. Whatever you do, the bacteria remain, albeit small. But water and soap are enough to neutralize it.
Solid soaps are also unhygienic in bulk use. However, this problem can be overcome with personal soap dispenser at home, work and school. Antibacterial soaps are generally liquid, although they seem to be of great benefit in the field of mass use, in fact when compared to dry soap in terms of content, dry soap appears to be one click higher. We explained the reasons for this a little below.
Alcohol-containing colognes are severely germicidal. Especially rubbing kills HIV, herpes, RSV, rhinovirus, vaccinia, influenza, hepatitis viruses, Tuberculosis virus and fungi. When you rub your hands with a cologne containing 70 percent alcohol for half a minute, 99.97 percent rubs for one minute and results up to 99.99 percent.
Since hand antiseptics are alcohol based, they do not cause any harm in the use of hand washing in public transportation and common areas. It is recommended to use even after hand cleaning after dirty works. According to CDC data, the US public health unit recommends rubbing hands with hand antiseptics, even if the hand is cleaned as a result of serious hand contamination.
Alcohol-free, gel-free waterless disinfectants cannot have as much effect as a soap's hand effect. Because the microorganisms at hand are still there.
Some people say that ash and mud clean up very well. Wet soil or mud can be effective from water. But it can't be effective from soapy water. Although it can disinfect in the ash like alkaline in the soap, it is recommended to use when soap is not available.

Do you wash your hands?
Many people know that after using the toilet, before eating, after getting on public transport, we need to wash our hands, and the serious illnesses that we described in the above article will be prevented. But did you know that the right and timely handwashing is only 5 percent, although it is known?
According to the latest research, according to data obtained from the observation of three thousand people, 10 percent of those who use public toilets come out without washing their hands, 35 percent of those who wash only hold water and not even use soap. As we have already mentioned, it is certain that microbes from unwashed hands are the source of entry to our body as we constantly take our hands to our face and mouth.
Researches in Brazil and the United States showed that in public areas, 3.3 times per hour, different surfaces were touched by hand, and 3.6 times were brought to our mouths and noses.
So we have to wash our hands properly. But what is the best way to do this?

How to clean the hands healthy and clean?
Warm water and soap, along with the wrists, fingers between the nails, palms rubbing the palms of the hands can be cleaned. Warm water cleans pores and removes pathogens, especially without removing oil from the skin.
Liquid soap can be made with one or two squeezing values to cover the surface of the whole hand 5 millimeters. Do not finish rubbing this hand before 20 seconds. If you pay attention, handwashing, wrists, thumbs, fingers and nails are always forgotten. However, this is where most bacteria or microorganisms or pathogens accumulate. Particular attention should be paid to people using false nails or those with broken nails.
A nice rinsing process is done with water and the microorganisms at hand go into the mite. 100 percent does not go again, your hands will remain.
This time it's a matter of closing the tap and hand-drying. Since you open the tap with a dirty hand, it is covered with a paper towel, which should not be touched by the cleaned hand. Drying hands and arms with paper towels is very important for good hygiene.
Never use clean hands to open the door. When disposing of napkins, of course you should not touch the trash.

Is hot water the way to clean your hands well?
Most people believe that washing our hands with hot water is more effective. It's true that heat kills bacteria. That's why we heat food until it boils. The hot water that we wash our hands must be at the heat to burn the skin for it to be effective. For example, salmonella bacteria can survive for 10 minutes even at a temperature of 55 degrees. If you wash your hands with water at this temperature for more than 30 seconds, severe burns will occur .
After washing the hands with water at different temperatures (between 4.4 and 50 degrees), an experiment was conducted in Florida to see how much germ remains. The subjects' hands were washed with water at a certain temperature after touching the raw minced meat rich in bacteria. The hands were rubberized with gloves and a special liquid was added inside the glove to collect bacteria. One minute massage was applied to the hands to allow the bacteria to pass into the liquid. These liquids were then collected with a pipette and examined in the laboratory. Whether the hands were washed with hot or cold water, the same amount of bacteria remained.
However, a certain hand washing time was applied for this experiment. However, in real life, excessive hot or cold water may adversely affect the washing time. Therefore, warm water in public toilets can prolong the hand washing time.

Is anti-bacterial soap better than normal dry soap?
A lot of research has been done on this subject. When their results recovered in 2007, it was found that triclosan in anti-bacterial soap was not effective in reducing the number of bacteria at hand or preventing infection. A similar study in 2015 reached the same conclusion.

Should he dry hands after washing?
When we are in a hurry, we wash our hands and leave them to dry. When leaving the toilets, we can leave the washed hands wet, not a problem, but you should not touch any objects. It should definitely be dried when you leave, as it would require cogging. It is much easier to smear bacteria in the wet hand.
In addition, during the drying process, some of the microbes that have been recovered are saved. You will also see that drying with a paper towel at the bottom just removes the remaining bacteria.

Dryer or towel?
There is a lot of discussion about this. Most research suggests disposable paper towels. In addition, longer drying times can be a deterrent for some.
But today, there are devices that do this job in a shorter time. However, it is pointed out that these jet dryers may spread germs to the atmosphere in the space. In a study, it was seen that these devices, which blow strong air, can blow germs up to 3 meters away. However, much of this research is financed by paper towels manufacturing companies.
In the public toilets rather than the laboratory, these researches should be repeated and the preferences of the people should be taken into consideration.
In addition, a research conducted in the United States, clean public toilets in hand washing rate was found to be much higher than the dirty.
Regardless of how we wash and dry our hands, research shows that the washing process should be carried out in a much longer and more versatile way than we thought. The hand washing process, including palms, fingers, nails, hands, wrists, should take at least 15-30 seconds.

Is Hand Dryer Useful?
A serious research conducted in 2008 explains how much damage the hand dryer does. The University of Westminster observed the effectiveness of paper towels and hand dryers.
The number of bacteria increased by 200 percent in fingers, 250 percent in palm, while the number of bacteria in paper towels decreased by 76 percent and 77 percent in palm.
There are also very fast hand dryers. When they tried them, 42 percent of the fingers, a 15 percent increase in the palm was observed again. The paper towel maintained the same figures, on the contrary, provided a decline.
The worst part is that compressed air is thrown into the hands, throwing existing bacteria at distances of almost 3 meters. Thus, it causes people to breathe directly through the mouth and nose. The devices that dry with hot air throw the viruses up to 25 cm.
However, the paper towel has not been closely related to such situations.
Therefore, in public WCs where there is a dryer, without using, if you have to take your hands with a napkin you have prepared beforehand and immediately exit. Because with each study, one-to-one convergence with viruses will increase.
