Dr. Sahil Chopra joins Dr. Jeff Graham to discuss sleep as a core driver of cardiometabolic health, cognitive performance, and long-term longevity. They break down how acute and chronic sleep deprivation affect physiology differently, why conditions like insomnia and obstructive sleep apnea are often missed, and how sleep disruption increases risk for cardiovascular disease, metabolic dysfunction, and neurodegeneration. The conversation also explores what "healthy sleep" actually looks like from a physiologic standpoint, the limits of consumer wearables, and how detailed sleep assessment can guide more precise, individualized care over time.

Dr. Erin Faules joins cardiologist Dr. James Min to discuss how coronary CT angiography can identify coronary artery disease before symptoms appear. They explain why plaque itself—not cholesterol levels or stress tests—is the underlying disease, how plaque type and burden shape cardiovascular risk, and why many heart attacks occur without prior warning. The conversation explores how imaging can guide more individualized prevention, inform treatment over time, and shift cardiology toward earlier, disease-focused care.

Dr. Erin joins Wild Health coach Steve Holt to unpack VO₂ max—what it actually represents, why it's closely tied to all-cause mortality, and how heart, lung, vascular, and mitochondrial function all contribute to it. They walk through practical ways to build an aerobic base, use interval work to raise your threshold, and apply zone-based training with or without wearables. The conversation focuses on evidence-informed methods to improve cardiorespiratory capacity in a sustainable way, whether you're new to training or already well-conditioned.
