Why does looking at the sun make me sneeze?

Over deze aflevering

We usually sneeze to protect ourselves from irritants such as pollen, dust, or chemicals. But there are some people who consistently sneeze when they look at the sun.

If it happens to you, perhaps you’ve been wondering if it’s an allergy to sunlight, but actually it isn’t. The reaction triggered by sudden exposure to light is called the photic sneeze reflex. It is a congenital physiological anomaly that’s pretty common and totally harmless. Why does this reaction occur? What happens in the body when we sneeze? Should you suppress a sneeze?
