Our hands are in use and in contact all day long with other people and with objects. Whether we are holding handrails on the subway, typing on our phones or blowing our nose with a handkerchief, bacteria and germs are left behind by touching surfaces with our hands.
By washing our hands regularly and properly, we get rid of potential germs. This is important for our health, because almost 80 percent of all illnesses are transmitted via the hands — especially gastrointestinal infections, conjunctivitis and flu.
In addition, bacteria and dirt can get from the hands to the skin on the face and cause pimples.
However, washing your hands too often strains the skin and dries it out. That is why you should apply cream to your hands after every wash.
