Why We Sneeze

Whether you are in a meeting, a seminar, or a funeral you can’t escape it. The impulse to sneeze will get you wherever you go. Lets take a look at why we sneeze, and some possible ways we can prevent ourselves from sneezing to avoid the possible awkward situations it can put us in.


General Function Of Sneezing:

Function Of Sneezing

Sneezing is a defense mechanism that protects the respiratory system from irritant materials entering it. Sneezing is a sudden, strong, and forceful burst of air through the mouth and nose.

The violent exhalation during sneezes occur to clear the upper airway. If this does not occur these larger particles could go further into the respiratory system and cause significant harm.

The nose is one of the two main pathways for air to enter into the lungs. With hairs on the inside the nose acts as a good filter helping to prevent dust and large particles from entering the respiratory tract and allowing for air to reach body temperature before it gets down into the lungs. The parts of the body involved in the process of sneezing are:

  • The Nasal Cavity
  • Nasal Hairs
  • Trigeminal Nerve

The trigeminal nerve, or its endings, is responsible for picking up the stimulation from particles that triggered the nose hairs and results in the sneeze reflex. Basically, you can view a sneeze as a nerve impulse taking place.

Common Triggers For Sneezing:

Common Triggers For Sneezing

Sneezing is a very common side effect of nasal congestion which can be a side effect of many different illnesses. However, there are many different stimuli that can trigger a sneeze reaction such as:

  • Rapid changes in environmental temperature
  • Upper respiratory tract infection
  • Allergies to mould via inhaling spores
  • Seasonal allergies from pollen inhalation also known as hay fever
  • Inhalation of fine particles in the environment like smoke, hair, or dust.
  • Looking at bright light, also known as photic sneeze reflex

Helpful Ways To Prevent Sneezing:

Prevent Sneezing

Whenever it comes to preventing a sneeze the best action is to eliminate the triggers. If possible getting an air filter for your home can go a long ways. This will help eliminate many large particles in the air that could trigger the sneeze. Avoiding fragrances and aerosols is another good place to start. Both of these can enter the nose and stimulate the nasal hairs causing a sneeze to happen.

If you are unable to eliminate the triggers then carry a tissue with you and whenever you feel a sneeze come one simply pinch your nose and it will most likely go away, however if you don’t catch it soon enough, let the sneeze out. It could cause damage if you hold the sneeze in.

For longer term solutions making sure you don’t have any nutrient deficiencies will make a massive difference in how you respond to many of these triggers.


Overall, sneezing is a necessary response in order to keep the respiratory healthy. Without sneezing we would easily get large particles into the respiratory tract and have recurring infections, trouble breathing, and potentially die.
