36 分钟Welcome to Huberman Lab Essentials,
where we revisit past episodes for the most potent and actionable science-based tools for mental health,
physical health, and performance.
I'm Andrew Huberman,
and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine.
Today, I have the pleasure of introducing Dr. Craig Heller as my guest on the Huberman Lab podcast.
And now for my discussion with Dr. Craig Heller.
Great to have you here.
It's good to be here.
I know that I and many people have a lot of questions about the use of cold.
So one of the things that's happened in recent years is that for many reasons,
people have become interested in things like taking cold showers and taking ice baths for many different purposes.
Could you just tell me a little bit about what happens when I get into a cold shower?
or an ice bath?
Well, first of all, you get a tremendous shock.
And what that's going to translate into is a bit of a shot of adrenaline.
And I think this is really the so-called benefit,
but it doesn't necessarily translate into any benefit in terms of your physiology or performance and so forth.
If you take a cold bath or a cold shower, a couple of things are happening.
One is you're going to stimulate vasoconstriction.
