Hands go through a lot each and every day as they're constantly being used to pick things up, type on a keyboard, hold onto a handrail, blow your nose and many more. We're also in constant contact with other people. By touching surfaces throughout the day, bacteria and germs stick to your hands.
By washing your hands regularly and properly, and for at least 20-30 seconds each time, you get rid of potential germs. Almost 80 percent of all illnesses are transmitted via the hands –especially gastrointestinal infections, pinkeye and the flu.
Bacteria and dirt can also get from your hands and then on to your face where it can cause pimples if you're not washing your hands regularly and thoroughly.
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 hand washing.
