Is cold water effective?
This leads to the money-saving trick of always washing your hands with cold water. This saves resources and also saves money. But the question that arises is whether cold water also removes germs sufficiently. Especially in times like these, when Covid-19 cases are on the rise again and colds are calling, one should be especially careful. In any case, health comes first.
The duration of hand washing is decisive
However, the website infektionsschutz.de, a site of the Federal Centre for Health Education, assures: Whether cold or warm water is used for hand washing is not relevant. What really determines whether bacteria are killed is how long you wash your hands. According to the website, you should wash your hands thoroughly for at least 20 seconds.
Using soap helps
Soap should not be avoided. For one thing, surfactants kill the germs on our skin and make our hands thoroughly clean. But, those who use soap usually wash more thoroughly anyway to remove soap residue as well. So it has two effective advantages at once. Infektionsschutz.de advises washing your hands especially after visiting the toilet, before eating, after coming home and after contact with animals.
