This is called the photic sneeze reflex, and it affects about 1 in 4 people. When bright light suddenly hits the eyes, it overstimulates the optic nerve, which can “spill over” to the trigeminal nerve — the one that controls the sneeze reflex. Your brain mixes up the signals, and… achoo!
Do you have such experience ?

I have never heard about this . This is new information for me , thanks for Sharing
Very new to me. Thanks for sharing this information.
It’s so interesting how our body work !!
I do sneeze every time I step into bright sunlight, but I never actually knew about the neurological concept behind it. Thanks for sharing.
Thats informative wasn’t knowing about this before. Thanks for sharing!
Interesting information. Glad to know how our body response to instant exposure to sunlight.
Informative. Never heard about this before.
This is great piece of information. Thanks for sharing!
Yes, same happens with me. Doctor said my eyes have become weak, so now I have to wear glasses.
This is intresting I too have such issue sometimes but never thought for the reason thanks for the information
Oh, I’ve actually never experienced this myself. It’s so interesting to know that about 1 in 4 people have the photic sneeze reflex! The way our brain and nerves react in such unexpected ways is really fascinating.
Sneeze during sunlight this neurological changes in the body i never know about this thanks for sharing
Not yet! I am hearing it for the first time! Thanks for sharing!
New to me, thanks for sharing.
Yes, I’ve felt that sudden sneeze when stepping into sunlight especially after coming out of a dark room. It’s strange but kind of funny too! I didn’t know it was called the photic sneeze reflex until now. Your explanation made it easy to understand, and I liked how you connected nerves and light
Very interesting i was not aware about this information before.
This phenomenon, called the “photic sneeze reflex” (or ACHOO syndrome ), affects about 18-35% of people . When exposed to sudden bright light (like sunlight), the brain may misinterpret signals from the optic nerve as nasal irritation, triggering a sneeze. It’s a harmless but curious genetic quirk!
Yes! I actually experience this too — stepping out in bright sunlight almost always makes me sneeze. Funny how our nerves can get their signals crossed like that!
