Between 25% to 33% of the population sneeze when they are exposed to light
I was surprised this percentage was so high. When I walk out into the sunlight I many times sneeze. If there is someone with me I will ask if this also happens to him or her. Most of the time they look at me like I’m nuts.
For those who have not experienced a light activated sneeze you don’t know what you are missing. They feel great!
