I start every day by jumping in freezing cold water! In all of my homes, I have a cold plunge that I keep at 56 degrees. [When I am] in Sun Valley, I have the river, which I jump into even in the winter! I do this as a daily practice, as a discipline to make my mind know that when I say I’m going to do something, I do it now—no matter how difficult it may seem. It also has amazing physical value for the body. Every cell, nerve, and muscle in your body pumps like crazy when you make that radical of a temperature change. It moves your lymph and makes you ready for anything. Completely invigorating.
