Why can't sneeze cover mouth?

It is impossible to avoid sneezing in our daily life. Do you know why you can't cover your mouth when you sneeze? Why do you close your eyes when you sneeze? Let's take a look.

Why can't sneeze cover mouth

When coughing or sneezing, cover your nose and mouth with your hands to block droplets that can spread germs to your hands. When you sneeze, the pressure in the pharynx increases and bacteria can easily enter the middle ear tympanum from the eustachian tube, which can cause inflammation of the eustachian tube or cause purulent otitis media. On the other hand, when you cover it with your hands, you prevent the spread of bacteria, but the bacteria, the virus, can stick to your hands and live for up to three hours.

Sneezing helps the body expel a lot of bacteria and foreign objects from the body, keeping the airways open. If you don't sneeze, you're swallowing bacteria back. During flu season or when respiratory and allergic diseases are at high risk, covering your mouth or pinching your nose can easily cause bacteria and viruses to stick to your hands and spread by shaking hands, touching doorknobs, computer keyboards and other surfaces. If bacteria and viruses stick to hands and get into people's eyes and noses, the damage is even more serious.

When a person sneezes, the upper respiratory tract will produce strong pressure. If the mouth and nose are completely covered, the pressure cannot be relieved will "return" to the inside, resulting in increased pharyngeal pressure, and then impact the eustachian tube, and even damage to the tympanic membrane. When serious, the tympanic membrane can be perforated, or cause nosebleed, nasal bone damage, etc. In addition, bacteria may also be driven to the middle ear tympanum by the eustachian tube with airflow, causing suppurative otitis media, sinusitis and other diseases, and sometimes even life-threatening.

It is not right to want to be elegant but not to pay attention to health. Holding a sneeze does a lot of harm to the human body. So how should we sneeze? In fact, if you want to sneeze, you have to sneeze. In more formal occasions, in order to behave appropriately, you can use handkerchiefs, tissues and other light cover the mouth, to prevent the saliva particles and germs brought out by sneezing everywhere. If the nose is easily irritated and you want to sneeze, it is recommended that you sneeze in the elbow socket instead of covering your mouth with your hand to avoid the spread of bacteria and viruses.

Why do you close your eyes when you sneeze

It's a defensive instinct. You feel relaxed after a sneeze, because sneezes expel a lot of gas from your lungs, mouth and nose.

Sneezing can be triggered by any number of factors, including external stimuli, physical reactions, pollen allergies, dry, pungent dust, nasal congestion, and sore throat. The respiratory system's instinctive defense response to a stimulus is to sneeze. Sneezing gives people an inelegant feeling, so people who want to sneeze in public or under special circumstances will hold it, which is not good for their health. Should UNDERTAKE NORMAL PHYSIOLOGY DETOXIFICATION, COVER MOUTH AND NOSE WITH PAPER, DO NOT SNEEZE TO OTHERS, AFTER ALL THIS IS PHYSIOLOGY REACTION, WHO CAN HAVE. Don't be so hard on yourself. Trying not to sneeze is actually bad for you, distracting you and making you feel bad.

When there is a foreign body in the nose, the body will react, and other organs will cooperate to complete the process of removing the foreign body. In this process, the lungs will contract and pressure the air, and then the air will be pumped up, and the foreign body will be rushed out of the nose with the airflow, and the foreign body will feel refreshed. The human body is a pretty smart organism, always able to defend itself through line after line of defense.

Sneezing, known to scholars as the sneeze reflex, protects the nasal cavity from foreign objects by forcing air out of the lungs at 10 miles per hour. (Earlier reports suggested that air travels at 100 miles per hour during a sneeze, but a 2013 study published in the journal PLOS ONE showed that six volunteers sneezed at 4.5 meters per second, or 10 miles per hour.)

A sneeze, however, involves more than the ejection of air and other foreign objects. When we're stimulated, the brain stem's sneeze center orders muscles from the esophagus to the sphincter to contract, including those that control the eyelids. Some sneezers even squeeze out a few tears.
