Do you know what causes sneezing?

In medical terms, sneezing is the sudden and uncontrolled outburst of air through the nose and mouth. It is the most common way for the human body to remove foreign particles such as dust, smoke, pollution, bacteria, and many more. It keeps your body safe by clearing the bacteria and viruses from the nose.

Is this the only reason which causes sneezing? The answer will be no, as various reasons may cause sneezing. Here, we will talk about the most common reasons for sneezing. So, let’s get started.

What Causes Sneezing?

The nose, one of the human body’s five sense organs, does not just help to breathe, but its job also includes cleaning the air and ensuring it is free of bacteria and dust particles.

However, sometimes foreign particles might enter your nose and might irritate the soft and delicate hairs in your nose. Sneezing occurs when there is an irritation in the mucous membranes of the throat.

It sends a signal to the brain, and the brain responds to it by preparing itself to sneeze. It can be triggered by various reasons, which are explained below in detail.


Seasonal allergies are one of the most common reasons for sneezing. In the case of allergy, a sneeze is often triggered by common allergens (pollen, dust, mold, virus, bacteria). When these allergens enter your mouth, and you breathe through it, the immune system detects and attacks them.

Then, the immune cells release a chemical known as histamine and send the electric signal to the brain. The body reacts to histamine by nose and throat becoming itchy and nasal passages swollen. This is when your brain sends the signal to the muscles of the chest to contract, and then you sneeze.

Allergic Rhinitis, also known as Hay Fever, is a very common condition defined as the body’s natural response to specific allergens. The common symptoms are uncontrollable sneezing, itchy and watery eyes, and a red and runny nose. The common treatment of Allergic Rhinitis is to avoid triggers that may lead to an allergic reaction.

Common Cold or Flu

Sneezing is often seen as one of the early symptoms of cold and flu. The symptoms of the common cold include a stuffy and runny nose, watery eyes, sore throat, coughing, fever, headache, and body ache.

When cold viruses interact with the mucous membranes, the immune system releases natural mediators, which cause blood vessels to dilate and releases mucus. The release of mucus leads to irritation which causes sneezing. It will disappear when the cold is treated.

Sometimes, it is difficult to identify the cause of sneezing as the allergic reaction, and the colds might be confusing. However, you can always see a doctor and ask him for important medicine to treat colds, allergies, and coughing. The treatments will help you in sneezing.


Sometimes, most people sneeze as the result of infections. Infections caused by viruses and bacteria play a vital role in making people sneeze. There are almost 200 viruses that lead to the common cold and infections.

Other sneezing triggers

People sneeze due to other sneezing triggers, including exposure to bright light, spicy foods, air pollution, dust, pollen, allergy, and dry air. Sometimes, medicine can also make you sneeze.

If you go out in the bright sunlight, you may tend to sneeze when looking at the sun. If you do this, you are not alone. In research, it has been found that it affects approximately one-third of the population. This process is known as the photic sneeze reflex.

Most people sneeze as a result of sexual thoughts and sexual arousal. It has been proved that most people sneeze during their orgasms, which is normal. Both men and women can experience sneezing during this phenomenon. Plucking your eyebrows can also irritate mucous membranes, which leads to sneezing. Sometimes, exercise also acts as a trigger for sneezing.

Sneezing is not a disease, nor does it mean any severe problem, but if you are experiencing frequent sneezing, it would be better to consult a doctor as soon as possible and treat them.

How to Stop Sneezing?

Sneezing is rarely a sign of a severe medical problem, but frequent sneezing can be irritating. So, here are some sneezing treatments to stop them.

If the cold and flu is the reason for your frequent sneezing, the best way to relieve sneezing is to treat them. Sneezing will disappear once the cold is treated. Hot water is very helpful in sneezing due to cold or flu. Take the hot water in a large bowl and inhale the scheme properly.

If the allergy is the reason for sneezing, it is advisable to stay away from the allergens. The most common allergen includes pollen, dust, peanuts, milk, dairy products, etc. If you don’t know them, you can always visit a doctor and learn about them.
