1. It is wrong to cover your mouth and nose with your hands when sneezing.
Experts say that the idea of covering your mouth and nose with your hand when sneezing is correct, but the action is wrong. Sneezes and coughs should be covered with a tissue, handkerchief, or on the arm. When coughing or sneezing, people habitually cover their hands to prevent foaming at the mouth and spreading germs around.
When you sneeze, cover your mouth and nose with your hands, and the saliva foam that comes out of the spray will stick to your hands, so a large number of germs remain on your hands. When you shake someone's hand or touch something else, the virus spreads.

When you sneeze and cover your mouth and nose with your hands, the virus will stick to your hands, and as you rub your eyes and pick your nose, the virus is likely to enter your eyes and nose through contact, causing infection in these areas to a certain extent.
In addition, if the mouth and nose are completely covered when sneezing, the strong pressure generated by the upper respiratory tract is not relieved, and the pressure will act on the ear canal and eardrum through the eustachian tube, which is not conducive to ear health.
