The water temperature has no influence on the reduction of the microorganisms. Therefore, the individually comfortable water temperature should be selected. Much more important are the duration of hand washing and the amount of friction when lathering the hands.

With thorough hand washing of at least 20 seconds, the germs on the hands can be reduced to a thousandth and less. However, according to a survey by the BZgA in Germany, more than half of the respondents wash their hands for less time. This means that they do not effectively reduce the germ count on their hands when washing their hands and thus have an increased risk of becoming ill themselves or of passing germs to others.
The optimal duration of hand washing also depends on the specific situation, such as the extent to which the hands are soiled. In the case of heavily soiled hands, soaping and washing of the hands for a period of 20 seconds is often too short and is therefore only a guideline for normally soiled hands in everyday situations. As a guide: 20 seconds is roughly the double hum of the Happy Birthday song.

Washing your hands with soap is much more effective than with water alone, because detergents remove dirt and microbes from the skin. In addition, there is a tendency to rub and wash hands more thoroughly when using soap than without, which leads to additional mechanical removal of germs. Certain germs are also found in the skin's natural fatty film and can hardly be removed with water alone.
If there is no soap available, you should still wash your hands with just water. Because even with water alone, at least some of the pathogens are removed. Even if the use of soap significantly increases the effectiveness of hand washing, studies have shown that just washing your hands with clean water, for example, can reduce the frequency of diarrhea.

To date, there have been no studies showing that the use of soaps with antibacterial additives in the general population (not including health professionals) brings additional benefits. If the hands are washed thoroughly, normal soaps are also able to remove germs that cause diarrhea and respiratory diseases, for example.
For example, in a study by washing hands, the frequency of e.g. For example, pneumonia and diarrhea can be reduced by at least 50 percent, but there were no differences between the use of soap and antibacterial soap in terms of the incidence of the disease.
It is important to use a sufficient amount of soap: In a further study it was shown that the use of more soap leads to a greater decrease in the number of bacteria in both normal and antimicrobial soaps.

In a humid environment, microorganisms can hold on and multiply better. Therefore, hands should be dried quickly after washing. In addition, drying your hands with a towel by rubbing them away also removes the germs that are still on the hands or in the water on the hands.
Therefore, drying your hands is an integral part of effective hand washing. To dry off, you should preferably use clean, disposable towels in public sanitary rooms to ensure that the towel is not itself contaminated with germs.
Hand dryers can also be used to remove moisture and microorganisms detached from the skin by washing your hands. While older hand dryers dry hands relatively slowly, modern devices can dry hands in 10 to 15 seconds.
When comparing the different methods of drying hands, most of the research results suggest that disposable towels are effective in drying hands and effectively removing bacteria. In addition, the washroom is least contaminated with germs in this way.

Correct hand washing protects against contagious infections! Incorrect or very frequent hand washing, especially at high water temperatures or with strong detergents, can, however, damage the skin: The protective acid mantle and natural skin oils, which keep the uppermost horny layer of the skin resistant, can be washed out.
The skin can dry out and skin irritation can result.
You should therefore prefer mild, pH-neutral washing substances when washing your hands. Rubbing your hands with a moisturizing and moisturizing skin care product supports the regeneration of the skin. Apply cream to stressed hands after washing or in between, as required.
In general, hand disinfection is not necessary in private surroundings. Disinfectants are not suitable for visibly dirty hands. If there is an increased risk of infection, it can be useful to disinfect your hands after washing your hands. These include, for example, cases in which family members are infected with bacteria such as salmonella, are colonized with multi-resistant pathogens or suffer from highly contagious diseases such as flu or norovirus infections. Even if people with weakened immune systems live in the household with an increased risk of infection or relatives in need of care are cared for, hand disinfection can be useful in certain situations.
When visiting the hospital, hands should also be disinfected when entering and leaving the infirmary.
