About

A small awareness site for a reflex with a silly name and a serious side.

Lots of people with ACHOO syndrome go years thinking they're the only one who sneezes at the sun. This site is here to give it a name, collect what the research actually says, and point out the few moments when it really matters, like coming out of a tunnel at 80 km/h.

The map is a simple, anonymous way to show how widespread it is. It isn't a scientific study. People choose to add themselves, so it will over-count some places and miss others entirely.

What this site isn't

It isn't medical advice, a diagnosis, or a substitute for your doctor. We don't sell anything, run ads, or track you.

Who runs it

This site is run by the ACHOO project, an independent, volunteer awareness effort. It isn't affiliated with any hospital, university, charity or company.
