Immersion diuresis is the name given to the phenomenon of getting into water and then wanting to take a tinkle.

This is the second in my series entitled 'Minute Medicine' where I try to explain an offbeat medical topic in as short a time as possible. So far I've made them during a brief break on a night shift! This is my excuse for why I look fatigued and have terrible hair, but let's be honest those things are true even when I'm not at work. If you haven't subscribed to my YouTube channel yet, then you are an awful, awful person.
