266 How to Get the Best Sleep of Your Life, According to Science

Board-certified sleep specialist Dr. Michael Breus returns to Behind the Brilliance for a wide-ranging and deeply practical masterclass on the three biological essentials that keep most people from thriving: sleep, hydration, and breathing.

He reveals how to improve sleep, energy, and long-term health and goes beyond basic wellness advice to help us understand the foundational mechanics that determine energy, health, and well-being. From jet lag strategies to weighted blankets to getting back to sleep in the middle of the night, Dr. Breus delivers practical solutions that work in the real world because they're tested on actual patients, not theoretical research.

Dr. Breus explains why sleep quality matters more than sleep quantity, why waking up at the same time every day is the single most powerful sleep intervention most people will never try, and how “social jet lag” sabotages performance and mood. The conversation dives into the three most common types of insomnia and the best ways to get deeper sleep. We also unpack supplements, melatonin, CBT-I, and when to see a professional.

Beyond sleep, Dr. Breus breaks down hydration myths and gives science-backed takes on the most popular wellness topics including breathwork, mouth taping, cold plunges, saunas, CBD, weighted blankets, and the explosion of misinformation in the wellness space.

The episode closes with a candid look at Dr. Breus’s own routines, his evolving relationship with meditation, and why leading by example is the real foundation of sustainable health.
