Sleep is the biggest performance multiplier most people ignore.

In this episode of the Superhuman Podcast, Riley sits down with Dr. Daniel Gartenberg (Dr. Snooze) - founder of SleepSpace, sleep scientist, and author of 20+ peer-reviewed papers - to break down what sleep actually does for your brain and body, why deep sleep matters for memory and long-term brain health, and how technology like sound, light, temperature, and AI will personalize sleep improvement over the next decade.

We cover:

  • Why sleep impacts nearly every chronic disease (including brain health and Alzheimer's risk)

  • Deep sleep vs REM: what's happening across 90-minute cycles

  • Why wearables can be useful but imperfect for sleep staging

  • The overlooked role of breathing and when to test for sleep apnea

  • Tools for better sleep: CBT-I, sunlight timing, smart lighting, and sound-based deep sleep stimulation

  • Lucid dreaming and "targeted memory reactivation" (and how to train for it)
