Why do we Sneeze!!?
Sneezing :
Sneezing is your body’s way of removing irritants from your nose or throat. A sneeze is a powerful, involuntary expulsion of air. Sneezing often happens suddenly and without warning. Another name for sneezing is sternutation.While this symptom can be quite annoying, it’s not usually the result of any serious health problem.
What happens when we sneeze?
When a foreign particle enters your nose, it may interact with the tiny hairs and delicate skin that line your nasal passage. These particles and contaminants range from smoke, pollution, and perfume to bacteria, mold, and dander.When the delicate lining of your nose experiences the first tinge of a foreign substance, it sends an electric signal to your brain. This signal tells your brain that the nose needs to clear itself. The brain signals your body that it’s time for a sneeze, and your body responds by preparing itself for the impending contraction. In most cases, the eyes are forced shut, the tongue moves to the roof of the mouth, and the muscles brace for the sneeze. All of this happens in just a few seconds.Sneezing, also known as sternutation, forces water, mucus, and air from your nose with an incredible force. The sneeze can carry with it many microbes, which can spread diseases like the flu.Sneezes also perform another vital role in the body. In 2012, researchers from the University of Pennsylvania discovered that sneezing is the nose’s natural way to “reset.” The study found that cilia, the cells that line the tissue inside the nose, are rebooted with a sneeze. In other words, a sneeze resets the entire nasal environment. What’s more, the researchers found that sneezing didn’t have the same “reset” effect on people who have chronic nasal issues like.
Why do we sneeze when we’re sick?
Just like our body tries to clear house when a foreign substance enters the body, it also tries to eliminate things when we’re sick. Allergies, flu, a common cold - they can all cause a runny nose or sinus drainage. When these are present, you may experience more frequent sneezing as the body works to remove the fluids.
Why do we sneeze when we have allergies?
Dust stirred up while cleaning may make anyone sneeze. But if you are allergic to dust, you may find yourself sneezing more often when you clean because of how frequently you come into contact with dust.
The same is true for pollen, pollution, dander, mold, and other allergens. When these substances enter the body, the body responds by releasing histamine to attack the invading allergens. Histamine triggers an allergic reaction, and symptoms include sneezing, runny eyes, coughing, and runny nose.
