Dr. Jack Feldman @jacklfeldman is a neuroscientist, the David Geffen School Chair in Neuroscience, and a Distinguished Professor of Neurobiology at The University of California Los Angeles. If you are a fan of Andrew Huberman and the “physiological sigh” you can thank Jack’s research for making that a thing. We’ve never really explored breathing in depth on this podcast but if you do a little bit of digging you’ll see that our breath is one of the most powerful tools we have for changing our state of mind. In fact, my biggest psychedelic experience so far involved zero substances but only my breath. So I brought Dr. Jack Feldman on to discuss everything we need to know about breathing and the brain for our mental and physical health.
