In medical terms, sneezing is an involuntary reflex caused by irritating our nasal mucus walls in response to a foreign agent. To eliminate the unfamiliar trigger, the body expels air from the lungs through the nose resulting in a sneeze. Yes, a lot happens in 0.06 to 0.3 seconds, the average of your sneezing.

Why do I keep sneezing? Potential Causes and Triggers

Sneezing is a forceful expulsion of air from the nose triggered by our immune system to eliminate the triggering agent. It is an involuntary action to protect our respiratory health from harmful triggers. Here are some potential causes of sneezing:


Ever felt phobic of something? Height, spiders, cockroaches, or even that cute puppy that wants to play with you. These are the things that may be normal to one person and are terrifying to another. Allergies operate in the same way. It occurs when your immune system identifies something as harmful and reacts to it even when it’s usually harmless. 

For example, fungus molds, dust, nuts, pollens, and some scents are common allergens. So, next time you wonder, “Why do I sneeze so many times in a row?” check for triggers or consult a doctor for your allergy test.  

Environmental Triggers

Some environments, like dusty atmospheres or pollens during spring/allergy season, cause many people to sneeze continuously. As per CDC stats, 25.7% of people in the US are diagnosed with seasonal allergies. Rhinitis or Hay fever are alternative names for pollen allergies.

Nasal Irritants

Various substances can irritate your nasal passages and cause a sneezing attack. 

Some people are allergic to smoke, especially cigarette smoke, often caused by passive smoking. In contrast, others found themselves with runny noses and sneezing around strong scents in perfumes, chemicals, cleaning products, or certain foods. 

Viral and Bacterial Infections

While most of the culprits of a runny nose are viruses like Rhinovirus, which causes flu or cold, some bacteria can also cause sneezing fits, like Haemophilus influenzae causing sinus infections. Viral infections last 7-10 days, while bacterial infection persists a bit longer—these infections, in addition to sneezing, cause other symptoms like nasal congestion, fever, and coughing. 

Other Causes

Sneezing can also be triggered by certain medicines that may have the flu or allergy side effect due to specific bioactive components. Studies show that bright light or sudden temperature changes can also cause sneezing. This happens because bright light constricts pupils and causes mucous secretion, which initiates sneezing.

Why do I sneeze after I eat?

We often eat something perceived as harmful by our body or eat too fast that some pieces of food get stuck in our airways which can cause sneezing as a way the body uses to protect you from harmful consequences. Various possible reasons can trigger post-eating or during-meal sneezing; here are a few prominent ones:

Gustatory Rhinitis

Gustatory Rhinitis is a non-allergic reaction to specific foods, including spicy foods, alcohol, hot beverages, or extremely hot or cold foods that trigger the nasal nerves and cause sneezing. Although this condition is not associated with allergies, it can give you an excellent runny nose and a lot of sneezing. So next time you munch on that Tabasco or Sriracha sauce, notice if you are sneezing after eating.

Food Allergies and Sensitivities

Some foods cause mild to severe allergic reactions, including wheat allergies (gluten allergy), dairy allergies (lactose intolerance), Nut allergies, etc. While some of these can cause swelling, itching, and hives, many can cause sneezing and runny nose in addition to those symptoms as an allergic response by the immune system. 

Nervous System Response

The parasympathetic nervous system regulates our normal body functions, from eating, digestion, and breathing to heart rate. Chances are that during eating, it is activated, and you sneeze as a reflex action. This response is not fully understood, but the goal is to clear the airways for optimal breathing and respiration. 


The medical term for snatiation, a combination of sneezing and satiation, is “ACHOO Syndrome,” short for an autosomal dominant compelling helio-ophthalmic outburst. It is a condition when a person sneezes in response to being satiate after eating a large meal. It is believed to be a combination of genetic and environmental factors, as many genes play a role in this condition, but underlying mechanisms are still unknown. 

Why do allergies cause sneezing fits?

If you are wondering why can’t you stop sneezing or why they occur in an endless series, it occurs mainly in response to allergens. Allergens, rather than viruses or bacteria, cause sneezing fits. The reason is the constant push from our immune system to flush out the allergy-causing particles from your airways through the nose. Common allergy symptoms include a runny or stuffy nose, itching or watery eyes, coughing, and fatigue.
