Title: Does placing the hand of a sleeping person in warm water cause urination? How?
Post by: Hank on 17/12/2008 20:41:34

Hank asked the Naked Scientists:

What physiological mechanism is at work in the old college trick of sticking a
sleeping person's hand in warm water to precipitate involuntary urination?

What do you think?

Don't know if it works. I would wake up if anyone even took a breath in my presence when I am sleeping.

I assume it is based on the myth/phenomenon that one relaxes when exposed to warm water.
