What Do You Know About Sneezing?

Most people, with or without allergies, sneeze almost every day, even several times a day, without even noticing it. You may sneeze at specific moments, or it may just happen out of nowhere. In this article, we will study the causes of sneezing, look at a number of interesting facts about this symptom, as well as disprove some popular myths.


Your Nerves Are Responsible for Sneezing


According to experts in allergy and asthma, sneezing is a responsibility of your nervous system. Whenever there is a trigger in your nose, the nerves transmit the information to your brain, resulting in a sneezing response.

Depending on how the signals are traveling along the nerves to and from the brain, different people may experience different sneezing scenarios.

Sneezing as Part of Your Body Protection


Sneezing is a part of the immune process, and it’s very important when it comes to natural body protection.

When you sneeze, bacteria and viruses accumulated in your nose are cleared out, which helps to keep us healthy. When your nose is affected by an irritant, the sneeze-evoking center in the lower brainstem sends a number of signals to tightly close your throat, mouth and eyes. Then, your chest muscles contract, followed by a quick relaxation of the throat muscles. All this causes the air, saliva and mucus in your nose and mouth to be forced out, resulting in a sneeze.

The Average Speed of Human Sneeze Is High


Specialists say that sneezes are able to travel at 100 mph pace. What is more, over 100,000 germs can be released into the air by a single sneeze.

Sneezing Can Be Triggered by Sunshine, Exercise, Sex, and Other Things


There are many potential triggers of sneezes. For example, when plucking your eyebrows, you may affect a nerve in your face that is linked to your nasal passages, which will likely lead to sneezing.

Exercise can also make you sneeze. When you are exercising, your nose and mouth tend to dry up, as a result of hyperventilation. When you nose starts to drip reacting to dryness, it causes you to sneeze.

In addition, around 30 percent of people sneeze because of bright sunlight. This condition is known as light sensitivity, and it can be inherited.

Finally, sneezes can also be triggered by sex. According to researchers, when the parasympathetic nervous system is stimulated in some people, they tend to react by sneezing, when the act of sex is over.

Sneezing While Sleeping Is Rare


Normally, when you are sleeping, the nerves responsible for sneezing are sleeping too. Therefore, people don’t usually sneeze in a sleep.

Can You Prevent a Sneeze?


Sometimes, you can stop a sneeze by breathing through your mouth and pinching the end of your nose. However, there is no guaranty that this method will work.

What Are the Common Myths About Sneezing?


Some people believe that sneezing causes your heart to stop. However, it is not true. When your chest muscles contract during sneezing, it leads to a rapid constriction of your blood flow too. As a result, the rate of your heartbeat may alter, but it doesn’t stop.

According to another sneezing myth, sneezes may cause your eyeballs to pop out of your head. In most cases, you would naturally close your eyes before sneezing. However, if you do keep them open, there’s nothing to worry about. Your blood pressure behind the eyes does increase a little bit because of sneezing, but your eyes will definitely stay where they belong.
