We've all experienced it: the sudden urge to pee when it's cold is a common thing. This connection was supposedly discovered by Austrian physician Alfred Adler back in 1918. His experiment involved injecting cold water into a bladder to see how the body reacts. You might think it caused the kidneys to contract, but that's not the case...

What did Adler discover then? Are there other factors explaining the link between the bladder and cold? What can you do if you struggle to hold it in?
