Covering your mouth and nose with your hands when sneezing does prevent some saliva from spreading to the surrounding air, but the saliva will attach to your hands, so a large number of germs remain on your hands. If you touch the surface of other objects without washing your hands, you may spread influenza virus to others through touching.
In addition, if people cover their mouths and noses completely when sneezing, the strong pressure generated by the upper respiratory tract will not be relieved, and the pressure will act on the eardrum of the ear canal through the eustachian tube, which is not conducive to ear health.
Therefore, it is important to master the correct posture when sneezing. To block the spread of bacteria and avoid infecting others, the correct way is to cover your mouth and nose with paper towels when sneezing or coughing, and then throw the paper towels into the garbage can. If you don’t bring a paper towel, you can hit your arm. Although the spittle is attached to your clothes, it can at least stop the spread of cold virus. If you cover your mouth and nose with your hands, you must wash your hands in time to avoid secondary pollution to door handles, telephones and other items.
In order to prevent catching colds, we must form the habit of washing hands frequently. Especially in places with dense crowds, especially in hospitals, stations and other areas where germs are easy to carry, we must pay attention to washing hands in time.
