ACHOO ☀️🤧 فرج The photic sneeze reflex (also known as ACHOO syndrome, acronym for Autosomal-dominant Compelling Helio-Ophthalmic Outburst) is an inherited and congenital autosomal dominant reflex condition that causes sneezing in response to numerous stimuli, such as looking at bright lights or periocular (surrounding the eyeball) injection. The condition affects 18–35% of the world's population, but its exact mechanism of action is still not well understood. Bless you 🤍 | Doctor Jules

😤 Sneezing is a reflex action that occurs when the nasal passages are irritated, triggering an involuntary expulsion of air from the nose and mouth. This reflex is the body’s way of clearing irritants like dust, pollen, pet dander, or pathogens such as viruses and bacteria from the nasal cavity.

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
