A situation familiar to everyone, when leaving a gloomy entrance, underground parking, etc., a person begins to sneeze at the sight of the bright sun.
It turns out that this is not an individual feature, not a pathology, and not an accident. It is a reflex.
While studying this problem, scientists came to the conclusion that when leaving a dark room for bright light, approximately every third inhabitant of planet Earth sneezes.
In terms of its prevalence, this is simply a colossal problem, but there is still no explanation for this phenomenon.
Whether it was a syndrome or a reflex, they first began to study it 74 years ago in France.
A curious idea came to the scientist's mind when he noticed that patients sneezed if he shone an ophthalmoscope into their eyes during an examination.
Digging a little deeper, the researcher found that some of his patients also sneezed when a camera flash went off.
It was further concluded that patients sneezed only when they moved from darkness into bright light.
In 1964, new research found that 17-35% of the world's population sneeze when exposed to bright light.
Modern researchers have already given a name to this phenomenon – autosomal dominant photic sneeze reflex.
And in 2010, it was discovered that sneezing is associated with polymorphism, which is related to epileptic seizures caused by flashes of light.
There is another suggestion that the eyes and nose are connected by the trigeminal nerve.
But science could not advance further than this and could not explain with certainty how bright light in the eyes makes a person sneeze.
