Your face mask is working double duty to protect everyone: It keeps you from spreading your germs and can stop other germs from getting into you. However, if used thoughtlessly, the masks can also cause unwanted side effects. Here’s what they are—and how to prevent them.
1. They Can Mess With Your Sight.
“Wearing a face mask makes the exhaled air go into the eyes,” wrote Antonio I. Lazzarino, Medical Doctor and Epidemiologist, of the University College London, in a letter to the journal BMJ about the side effects of face masks. “This generates an uncomfortable feeling and an impulse to touch your eyes. If your hands are contaminated, you are infecting yourself.” Resist the temptation to touch your face, and wash your hands with soap for 20 seconds after contact with substances like door handles, elevator buttons, packages or anything else where germs thrive.
