Ben Greenfield has spent his career turning his own body into a laboratory. The biohacker, author, and human performance consultant joined Sean Kelly on the Digital Social Hour for one of the show's deepest dives into longevity — covering everything from red light therapy and sleep optimization to EMF exposure, grounding, and the careful use of psychedelics.
What makes the conversation work is its practicality. Rather than abstract theory, Greenfield walks through the specific habits he uses and recommends — how he structures sleep, filters water, times his fasting, and decides which trends in the biohacking world are actually worth the money.
