The other thing that I would like to ask you about is, in the sauna, of course, there's vasodilation, and perfusion of blood to the brain is a wonderful way to enhance cognition. There's even some really nice data showing that, during inhales as opposed to exhales, people are better at learning information. Believe it or not, during the inhale, you're taking in and absorbing and remembering more than during exhales. And these are beautiful studies done in humans, of course.
