ACHOO syndrome, or photic sneeze reflex, is when people sneeze in response to bright light, like stepping into sunlight. It’s actually pretty common—about 10-35% of people experience it.

While it’s harmless, it can be surprising or annoying, especially if it catches you off guard outside or while driving. VC @anabelle.jeann | Mahyar "Max" Maddahali, MD

😤 Sneezing is a reflex action that occurs when the nasal passages are irritated, triggering an involuntary expulsion of air from the nose and mouth.

When an irritant is detected, the brain signals the muscles in the chest, diaphragm, and throat to contract, forcing a rapid burst of air out at speeds up to 100 miles per hour.
