WHY DO PEOPLE SAY BLESS YOU ANYTIME YOU SNEEZE
Sneezing is a mechanism your body uses to clear the nose. When foreign matter such as dirt, pollen, smoke, or dust enters the nostrils, the nose may become irritated or tickled. When this happens, your body does what it needs to do to clear the nose it causes a sneeze. A sneeze is one of your bodys first defenses against invading bacteria and bugs.
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 its 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 noses 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. Whats more, the researchers found that sneezing didnt have the same reset effect on people who have chronic nasal issues like sinusitis. Figuring out how to reactive those cells may help treat these ongoing issues.

When is sneezing a problem?
Sneezing can be bothersome, especially if you find yourself running through a box of tissues every allergy season. However, sneezing is rarely a sign of a serious problem.
Some people with specific conditions may experience additional symptoms or complications if they sneeze too much. For example, people with frequent nosebleeds might experience more bleeding episodes with sneezing. People with migraines may experience additional discomfort if a sneeze occurs while a headache is present.
Not every person will respond to external stimuli or allergens the same as people around them. If you dont sneeze after walking in a hay field or taking a deep breath from a bouquet of daisies, dont worry. Some peoples nasal passages arent as sensitive.
If you begin frequently sneezing and cannot pinpoint any obvious cause, make an appointment to see your doctor. While a few sneezes may not be an indication of anything worrisome, its always better to talk about your new symptoms and look for an underlying issue than suffer frequent sneezing.
Whether you rarely sneeze or youre frequently reaching for tissues, its important that you practice proper sneeze hygiene. The water and mucus you expel with each sneeze can carry microbes and bacteria that spread illnesses.
If you have to sneeze, cover your nose and mouth with a tissue. If you cant grab a tissue quickly, sneeze into your upper sleeve, not your hands. Then, wash your hands with soap and water before touching another surface. This will help stop the spread of germs and disease.
