It occurs simply because when something is irritating or tickling inside of your nose then it is the body’s way of response to remove those unwanted foreign particles from our body. This type of body’s response is also known as a type of reflex action.

For those, who don’t know about what a reflex action is, it is a type of neuronal activity that allows your body to move instantaneously and suddenly without your knowledge in response to a nerve signal.

Let us understand reflex action with an example. Just, like withdrawal of the hands when one touches a hot object saving our hand from getting burnt. You don’t intentionally drag your hand off. It just happens without your control, right? Same like this, one sneezes when unwanted particles are irritating our nasal passage just to get rid of such an irritating particle.

The process of expelling mucus(a slimy biological substance for lubrication, protection, etc.) containing foreign particles or irritants and so finally cleaning our nasal cavity.

So, ever thought about what happens to your body when you sneeze. Keep Reading! I got it covered.

Sneezing is a common physiological response of the human body. It usually occurs when a foreign particle or external stimulant enters your snout, reaching the nasal mucosa, then it triggers the release of bio-chemicals like histamine in our body which may be because of any type of viral respiratory infections, filtered particles, substances that trigger allergic reactions or may also be due to smoke, pollution, perfumes, and cold air. This leads to the leakage of fluid from the various vessels in the nose. This triggers the nerve endings of the nose leading to a reflex action. And, thus it finally causes a sneezing effect and that leads to the rapid expulsion of air. This action thus helps in removing the various offending particles from the nose.

Anatomically, it is seen when the nerve reflex is generated in the brain than the soft palate and palatine uvula depress while the back of the tongue elevates thus causing to partially close the passage to the mouth expelling the air from the lungs through the nose(via. the nasal cavity). Because the closing of the mouth is partial, a considerable amount of this air is also expelled from the mouth. The force and extent of the expulsion of the air through the nose varies. Since the mouth remains only half closed, a lot of this air is generally and additionally expelled from the mouth resulting which the sneezing may be of low or very high intensity.

Why do people sneeze twice or more times?

As I have already mentioned above this is a repeating process to clear your nasal passage.
When an irritating particle enters your nasal passage it triggers the release of histamine from our body which irritates nerve cells in the nose. This activates and results in the sneeze. It’s a powerful release of air, expelling what’s in the nose that’s causing the irritation.

It may be common that you can sneeze two or more times. It is because if the irritating particle is still present there in your nostrils after the first sneeze, then your reflexes can trigger another sneeze. Your sneezing may repeat thrice or more times until and unless you are free from that irritating particle(s).

A phenomenon named photic sneeze reflex or solar sneeze reflex may help you understand why do people sneeze in the sun. This phenomenon may be defined as when someone affected with photic sneezing come in contact with bright light and sudden exposure to sunlight than it triggers the optic nerves(nerves that connects the eyes with the brain) to send the signal of bright light to the brain. This sometimes triggers the nerves connected to the nasal mucosa as well which sends a signal to the brain into thinking that there is an irritating particle in the nasal passage which eventually results in sneezing.
