Some people sneeze when you look at the sun or any other bright light source. it photic sneeze reflex.
He began writing about the middle of last century. This reflex is inherited autosomal dominant. It can be found in approximately 25% people. And I have it too.
No one knows exactly how it started photic sneeze reflex. Most likely somewhere intersect pupillary reflexes and ptarmic.
Interestingly, that he works only once. Then comes the period of immunity.
So what is the use of photic sneeze reflex?
Ptarmic reflex have animals. For them the great value has the sense of smell, the nose and the animal must be regularly cleaned. Animals such as cats or dogs sneeze predominantly through the nose. Have you ever sprinkles snot cat? With me it has happened.
Adults people sneeze more through the mouth. But in infants this reflex may be the only way to get rid of mucus. Kids breathe nose and snot need somewhere to evacuate. Photic sneeze reflex helps them to clean the nose.
Stories from the photic sneeze reflex are not always joyful. Sometimes sneezing attacks on drivers, when they go from a long dark tunnel. So an accident.
And yet we conducted research with the participation of pilots of combat jets, and found that while sneezing they can lose control.
It seems that the damage from this reflex can be more than good.
