In this episode of the Commune Podcast, Jeff kicks off a new series on sleep — exploring why rest is one of the most powerful levers for improving our health. One in four adults isn’t getting seven hours a night, and the consequences are immediate: insulin resistance, weakened immunity, emotional volatility, and chronic fatigue. Drawing from his new Sleep Essentials course, Jeff breaks down what’s actually happening in the body when we fall short on rest — from metabolic disruption to amygdala overactivation — and explains why modern life makes it so hard to wind down. He also explores the evolutionary purpose of sleep, the biology behind deep and REM cycles, and the hidden nightly processes that repair the brain and reset our emotional balance. This episode sets the foundation for the rest of the series, offering a clear understanding of the sleep crisis we’re facing and why reclaiming healthy sleep is essential to our wellbeing.
