How to Enhance Your Immune System | Dr. Roger Seheult

About this video

Huberman speaks with Dr. Roger Seheult, a board-certified pulmonologist and sleep medicine physician who works in intensive care, about avoiding and recovering from colds, flu and other viruses. Dr. Seheult presents foundational pillars of immune health under the NEWSTART mnemonic coined by Dr. Neil Nedley, and explains his Swiss cheese model: no single protective measure is perfect, so layering many measures, as in an operating room, means a breakdown in one still leaves others in place. Huberman explains that the episode also covers long COVID, sun and red light for mitochondrial health, phototherapy’s established medical history, temperature and other levers, and how to get over sinus, lung and throat infections faster. On the flu shot, Dr. Seheult advises weighing risks and benefits with your doctor as an added layer, while noting risks including allergic reactions and a past European vaccine brand associated with a rash of narcolepsy that was stopped and never used in the United States.
