Brian Mackenzie: Respiratory Physiology, Stress Response, and CO2

Brian Mackenzie, founder and CEO of SHIFT, president and co-founder of the Health and Human Performance Foundation, and innovator in human performance on stress adaptation, chats with host Dr. Scott Sherr to discuss the importance of CO2 in respiratory physiology, why building up CO2 tolerance affects not only your parasympathetic and sympathetic nervous systems but your aerobic and anaerobic metabolism as well, the importance of nasal breathing, and more.
