Why do people sneeze when they look at the sun?
I do this all the time. Sometimes even if I look up in the sky with no sun at all. Maybe squinting our eyes twitches our nose or something and as react by sneezing. I'm not sure. Just a guess.
The exact reason why people sneeze when they look at the sun is not known. However, there are theories that try to explain sneeze reflex action and that of the eyes when they try to adjust to the light when they have come from dark as the cause.
I wonder that too I do it all the time
