10 Ways to Prevent and Fight Off Colds and Other Infections
Practice good hand hygiene.
The Centers for Disease Control and Prevention (CDC) estimates that up to 16 percent of respiratory infections and the vast majority of foodborne illnesses can be prevented by the simple act of washing hands with soap and water.
When washing your hands, be sure to lather well and rub your hands together for a good 20 seconds, getting in all the cracks and crevices, such as between your fingers and under your fingernails. Then rinse well and dry your hands using an air dryer or a clean towel or paper towel.
If possible, use a paper towel to shut off the water faucet and to open the bathroom door, particularly if you’re in a public restroom, because these surfaces have been found to be among the most contaminated with germs.
