How about sneezing and covering your mouth? Wash hands in time
Sneezing is a common thing, but a small sneeze can bring many germs.
Sneezing is a defensive reaction caused by the stimulation of the mucous membrane of the upper respiratory tract. Although sneezing is protective, it spews out a lot of nasal secretions, which are mixed in thousands of small drops of water. For example, tuberculosis, a large number of bacteria are present in the droplets. According to the test, the secretion can be ejected 3 to 4 meters away, and these small water droplets can float in the air all the time. If you use your hands to block the droplets, the germs will attach to your hands. When you touch the stairs, handrails and other public goods with your hands, the germs will be transmitted to them, which is easy to pass on to other healthy people. When sneezing, especially in public places, there are many people around, but also pay attention to civilized manners and health ethics.
At this point, we can:
1. When sneezing or coughing, immediately turn your face back to others, cover your mouth and nose with a tissue, and then throw the tissue into the garbage can;
2. If it's too late to cover, it's suggested to bend your hand and hit your arm to reduce the secondary transmission of the pathogen;
3. Cover your mouth and nose with your hands, and wash your hands in time to avoid secondary pollution to door handles, telephones and other items.
When sneezing, a normal stress response of the human body's nasopharynx to the irritant substances. Some people think that the action is not elegant, so what kind of damage can people cause by holding the sneeze?
First of all, sneezing can help the body to expel a large number of bacteria and foreign matters from the body and keep the respiratory tract unblocked. If you can't sneeze, it's equivalent to swallowing the bacteria again. When encountering the flu season or when encountering the high incidence of respiratory diseases and allergic diseases, holding sneeze and covering mouth with hand, or pinching nose, it is easy to cause the bacterial virus to stick on the hand, and spread by people shaking hands, touching the door handle, computer keyboard and other object surfaces. If bacteria and viruses stick to hands and enter people's eyes and nose by mistake, the infection of these parts will be more serious.
Secondly, when people sneeze, the upper respiratory tract will produce strong pressure. If the mouth and nose are completely covered, the pressure that cannot be relieved will "return" inward, resulting in an increase in the pressure of the pharynx, which will impact the eustachian tube and even damage the tympanic membrane. In serious cases, it can cause perforation of the tympanic membrane, or cause nosebleed, nasal bone damage, etc. In addition, bacteria may also be driven from eustachian tube to tympanic cavity with air flow, causing suppurative otitis media, sinusitis and other diseases, sometimes even life-threatening. In fact, if you want to sneeze, you have to sneeze.
