Why do we sneeze in the sun?

You’ve probably wondered many times why some people sneeze in response to sunlight. This phenomenon is quite common, but it has a scientific explanation. In this article, we will take a closer look at this phenomenon, find out why we sneeze in the sun, what is its scientific background and whether it is dangerous. Let’s start by explaining what sneezing is.

What is sneezing?

Sneezing is a physiological reflex of the body, which involves a sharp, sudden release of air from the nose and mouth in response to stimuli that irritate the nasal mucosa. It is a defensive reaction aimed at removing microorganisms, pollen, allergens and other irritating substances from the nose.

Various muscles participate in the sneezing process, including the diaphragm and abdominal muscles, which makes the air exhaled extremely strong and noisy. Sneezing is not only a defensive reflex, but also a social one, often making other people smile or laugh.

Achoo team

Some people seem to be more prone to sneezing in response to sunlight than others. This phenomenon is known as ACHOO Syndrome, short for “Autosomal Dominant Compelling Helio-Ophthalmic Outburst.” Although it sounds complicated, its name describes the essence of the problem – it is an inherited syndrome characterized by sneezing in response to exposure to sunlight.

People suffering from ACHOO Syndrome sneeze when they suddenly move from a shaded place to a brightly lit place. This phenomenon is not only interesting from a scientific point of view, but may also raise many questions about why some people are more susceptible to this reflex than others.

Why do we sneeze in response to the sun?

The cause of sneezing in the sun is related to the nervous system and central nervous system. The main theory explaining this phenomenon is the light reflex theory. According to her, exposure to bright sunlight can lead to over-stimulation of the optic nerve, which is linked to the sneezing nerve, which controls sneezing.

The cephalic nerve, also known as the vagus nerve, regulates many functions in the body, including the heart, stomach and respiratory tract. Excessive stimulation of this nerve may result in sneezing. Therefore, when we suddenly move from a dark room to bright sunlight, our nervous system may trigger a sneeze reflex as a reaction to this sudden light.

Can sneezing in the sun be dangerous?

In most cases, sneezing in the sun is not dangerous. This is the body’s natural reaction to a sudden change in lighting, and usually does not cause any serious health consequences. However, it is worth being careful and taking care of your eyes in brightly lit places, especially if you are a driver or work outdoors on sunny days.

Can the sneeze reflex be stopped?

You can try to stop the sun sneeze by wearing sunglasses or gradually reducing your exposure to bright light. However, it is not always possible to stop it effectively because it is a physiological reflex controlled by the nervous system. If you suffer from ACHOO Syndrome, you can avoid sudden changes in lighting or use eye protection to relieve the urge to sneeze.
