In this episode of the Commune Podcast, Jeff explores the architecture of sleep — the repeating nightly cycles that carry us from light sleep into deep restoration and vivid REM dreaming. He breaks down N1, N2, and N3 sleep, explains why deep sleep is essential for physical repair and immune function, and describes how REM helps us process emotion, creativity, and memory. Along the way, Jeff highlights the science behind hypnagogia — the imaginative threshold between waking and sleep that inspired minds like Einstein and Dalí — and how understanding these stages can help you wake with more clarity and ease. The episode then turns toward the body’s internal clock: the circadian rhythm. Jeff explains how light and darkness shape our hormones, energy, and sleep timing, why chronotypes differ from person to person, and how habits like late-night screens, irregular sleep schedules, caffeine, and evening meals can pull our rhythms out of sync. You’ll also learn how a few simple practices — such as morning light exposure, consistent wake times, and timing rest in 90-minute increments — can help reset your natural rhythm. Whether you struggle with groggy mornings, restless nights, or inconsistent energy, this episode offers a clear and grounded roadmap for understanding your sleep patterns — and aligning your life with the rhythms your body already knows.
