Have you ever held back a sneeze to avoid attracting attention? Doctors warn: it's extremely dangerous! Sneezing is a powerful reflex that expels air at speeds up to 160 kilometers per hour. It's like a hurricane or a high-speed train, but inside your body. Suppressing this powerful flow creates colossal pressure in the nasopharynx. This pressure can rupture the eardrums or even small blood vessels in the eyes. Imagine damaging the delicate capillaries of the eye due to an internal explosion. The most famous case occurred in 2018. A 34-year-old British man tore his throat while trying to suppress a powerful sneeze. He was hospitalized in severe pain. Dr. Anthony Ayma of the University Hospital of Leicester called it an extremely rare but real risk. It's not just the throat. Internal pressure can cause pneumomediastinum—an accumulation of air in the chest that can be dangerous for the lungs. Medical history has even documented extremely rare cases of rib fractures in people who tried too hard to suppress a sneeze. Sneezing is an important reflex that protects the body. So, when you feel a sneeze coming on, let it out! Simply cover your mouth and nose with the crook of your elbow, as recommended by the World Health Organization, for the health of everyone around you.
