Spinach and saunas: 20 tips to prevent colds and flu

Most cold and flu viruses are spread by direct contact. Someone who has the flu sneezes onto their hand, and then touches the telephone, a desktop or a kitchen glass. The germs can live for hours or even weeks on a surface, only to be picked up by the next person who touches the same object. So wash your hands often, for at least 15-20 seconds, with soap.

If no sink is available, sanitize with an alcohol-gel hand sanitizer.
