In our crowded, fast-paced modern world, preventing colds is harder than it used to be.
Cold viruses spread easily, most often by direct skin contact.
Although they can be transmitted through the air by droplets from sneezes and coughs, more often people pick up cold viruses by touching contaminated objects or shaking hands. As we spend more time in restaurants, malls, and stores we constantly handle and touch contaminated items and surfaces, increasing our risk of infection. Repeating this simple act frequently will do you more good for you than bottles full of vitamins. Vitamin C has been shown in several studies to reduce both the frequency and severity of cold symptoms. Higher doses may cause diarrhea for some people.
