Episode notes

In this Huberman Lab Essentials episode, my guest is Dr. Jack Feldman, PhD, a Distinguished Professor of Neurobiology at the University of California, Los Angeles, and a leading expert in the science of breathing.

We explain the mechanics of breathing and the neural circuits that generate and regulate our breathing rhythm. We also discuss how breathing patterns profoundly influence mental states, including their role in reducing anxiety and enhancing emotional resilience. Dr. Feldman also shares practical tools, such as box breathing for daily performance and magnesium L-threonate supplementation to support cognitive health and longevity.
