Dr. Ivan Rusilko breaks down sleep architecture and explains how delta and REM sleep drive healing, hormones, brain health, and longevity.

In this episode, I break down the architecture of sleep and why it’s the foundation of healing, regeneration, and longevity. I walk through the different sleep stages—from alpha and light sleep to deep delta and REM—and explain how each one affects hormones, brain health, immune function, and emotional balance. Sleep isn’t rest—it’s active repair. If sleep isn’t optimized, nothing else in medicine truly works. This is part one of a deeper sleep series.
