Essentials: Breathing for Mental & Physical Health & Performance | Dr. Jack Feldman

In this episode of Huberman Lab Essentials, Andrew Huberman interviews Dr. Jack Feldman, an expert on respiration, about the mechanics of breathing and its interaction with the brain. Dr. Feldman explains how breathing generates airflow for oxygen intake and carbon dioxide removal, emphasizing the role of the diaphragm and the pre-Bötzinger complex in the brainstem. The discussion covers the differences between nasal and mouth breathing, the discovery of the active expiration oscillator, and the importance of maintaining stable carbon dioxide levels for brain function. They delve into the function of sighs in maintaining lung health and explore the connection between breathing patterns and emotional states, referencing Dr. Feldman's research on how slow breathing can reduce fear responses in mice. The conversation also touches on the coordination of breathing with other bodily functions, such as heart rate and pupil oscillation, and concludes with a discussion on the potential cognitive benefits of magnesium threonate supplementation.
