A global health researcher at the National Institutes of Health in Bethesda, Md., found that people touched their faces an average of 3.6 times per hour. Not only does this transfer germs near your eyes, nose and mouth, but it also deposits bacteria onto your skin, which can cause inflammation and breakouts. Wash your hands often, use antibacterial solution when you can’t get to a sink, wear gloves when you’re out and about (and keep your hands warm, too!), and keep your hands away from your face.
