The 1 action when sneezing is the most harmful to your health

Sneezing is a very normal phenomenon in people's lives. After sneezing, people feel refreshed all over their body. However, most people think that sneezing loudly in public is very uncivilized. Women, in particular, pay more attention to their words and actions. They will cover their mouths with their hands or pinch their noses to try to hold back the sneeze. Of course, this method makes people behave more elegantly, but it poses a considerable safety hazard to people's physical health.

Sneezing is a natural defense mechanism of the human body and a violent behavior of the respiratory tract to reject foreign substances. When people's nasal mucosa is irritated, this stimulation is transmitted to the brain through the peripheral nerves, causing it to respond automatically. Next, people will take a deep breath, then contract the chest violently, and the gas in the lungs will be quickly and forcefully ejected from the trachea through the mouth and nose to drive away the irritating substances. So, sneezing is a normal stress response of the human nasopharynx to irritants, so what kind of damage will people cause if they hold back their sneezes?

First of all, sneezing can help the human body expel a large number of bacteria and foreign objects and keep the respiratory tract open. If you hold back a sneeze, it is equivalent to "swallowing" the bacteria back. If it is flu season or when respiratory diseases and allergic diseases are prevalent, covering your mouth with your hands or pinching your nose when you sneeze can easily cause bacteria and viruses to stick to your hands and spread through handshakes, contact with door handles, computer keyboards and other surfaces. If bacteria and viruses stick to hands and accidentally enter people's eyes and noses, causing infection in these parts, the harm to themselves will be even more serious.

Secondly, when a person sneezes, great pressure will be generated in the upper respiratory tract. If the mouth and nose are completely covered, the unrelieved pressure will "return" inward, causing increased pressure in the pharynx, which in turn impacts the Eustachian tube and even damages the eardrum. In severe cases, it can cause eardrum perforation, nose bleeding, damage to the nasal bone, etc. In addition, bacteria may also be driven into the tympanic cavity of the middle ear through the Eustachian tube along with the airflow, causing diseases such as suppurative otitis media and sinusitis, which are sometimes even life-threatening. The most harmful action when sneezing

In view of the above situation, we know that it is wrong to only want to be elegant without paying attention to health. Holding a sneeze has many harmful effects on the human body. So how should we sneeze? In fact, if you want to sneeze, you must sneeze out loud. In more formal occasions, in order to appear appropriate, you can lightly cover your mouth with a handkerchief or tissue to prevent saliva particles and germs from flying around when you sneeze. If your nose is easily irritated and you want to sneeze, but you don't have time to prepare a handkerchief, it is recommended that you sneeze into your elbow instead of covering your mouth with your hands to avoid the spread of bacteria and viruses through hand-to-mouth contact. Warm reminder, everyone should dispose of handkerchiefs and tissues after sneezing in time to avoid further spread of bacteria and viruses, and remember to wash your hands!
