Exercise is one of the most powerful tools for brain health—and in this episode, we break down the five scientifically validated pathways that explain exactly how it protects cognition. From BDNF-driven neurogenesis to improved cerebral blood flow and lower inflammation, we explore the precise mechanisms that strengthen memory, support brain structure, and reduce long-term risk of cognitive decline. Whether you’re focused on longevity, mental clarity, or optimizing daily performance, this episode translates complex neuroscience into clear, actionable insight.
Research shows that both aerobic and resistance training elevate BDNF, the molecule that fuels neuroplasticity and neurogenesis. We examine how sustained aerobic exercise increases hippocampal volume, why women with mild cognitive impairment often see faster gains, and how improved angiogenesis, arterial flexibility, and cerebral blood flow create a more resilient brain. You’ll also learn how lactate acts as a signaling molecule, crossing the blood-brain barrier to activate SIRT1 and further boost BDNF. Finally, we map the anti-inflammatory responses—microglial repair activity, reduced NLRP3 signaling, and lower systemic inflammation—that complete this multilayered defense.
