Ep. 4 The Case for Taking Sleep Seriously: What the Research Says and How to Use Your Data

Sleep is the most underrated lever in brain health. The research is unusually clear: what happens during deep sleep directly affects your risk of cognitive decline, the hormones that regulate hunger, your cardiovascular recovery, and your body's ability to clear the metabolic waste that accumulates in your brain every single day. Most people know sleep matters. Far fewer understand what's actually breaking it.This episode covers the science of why sleep is especially high-stakes for anyone thinking about long-term brain health, what the research says about glymphatic clearance, HRV, the sleep-eating cycle, and circadian consistency, and how tracking your own data can reveal the specific variables disrupting your sleep in ways general advice never will.The personal thread: three years of sleep data, a fasting protocol that accidentally improved sleep architecture, the discovery that alcohol and late eating affect sleep through completely different mechanisms, and what a continuous glucose monitor revealed about a 4am waking pattern that took months to explain.Show Notes
