Three of the most powerful, evidence-based levers for extending healthspan require no prescription: vigorous exercise, deliberate heat, and deliberate cold. In this presentation, Dr. Rhonda Patrick details how vigorous-intensity exercise, strategic sauna sessions, and targeted cold therapy each independently (and synergistically) enhance cardiovascular fitness, protect against cognitive decline, reduce inflammation, and improve overall metabolic resilience. She breaks down the evidence behind each intervention and outlines practical, protocol‑level guidance for using this powerful trio to meaningfully extend healthspan.
