Sneezing at the sight of Sunlight
there you might have an allergy sneeze sneeze when looking at the sun. Sounds strange but it's real. It's not a rare thing, because some people have a habit of sneezing when the sun on their faces. Then, what is the cause of this habit?
Pagon, a pediatrician in charge of genetic medicine at Seattle Children's Hospital said that the habit of sneezing while facing the sun it is derived and so-called "photic sneeze reflex."
Not only is caused by genetic factors, Pagon also explained that the large number of sneezes that do are usually the same and hereditary.
Interestingly, the present invention successfully solved by Pagon by accident while attending a medical conference with colleagues. They're on the subject, and by chance it is known that four out of 10 of them have this reaction.
"One colleague said that people in her family sneezes five times, three times in my family, and in others only one time," said Pagon, as reported by MSNBC.

Nicolas Langer, PhD, a researcher at the University of Zurich neuropsychological explained that reflex that occurs when someone sneezes this is not including the classic reflex involving the brain stem or spinal cord, but other cortical areas.
One theory offered Langer is that the visual system of the brain is more sensitive to light. When he saw the light, this system directly activates the somatosensory area which then triggers sneezing.
Another theory is that there are two adjacent nerve, the optic nerve and the trigeminal, so that the incoming light is also connected to the nose and cause sneezing.
Although it seems harmless, but people who have the habit should consider the type of work that will be theirs. Some professions, such as pilots, football athlete, or a job that is often exposed to the sun may not be suitable for people who have this habit.
