In brief: Photic sneeze reflex

Exposure to bright light such as sunlight elicits a sneeze in about 1 of every 4 individuals.
This phenomenon may be the consequence of higher sensitivity to visual stimuli in the visual cortex of the brain and of co-activation of somatosensory areas. This was evaluated by eeg.
