How well did you sleep last night?

Do you wake up feeling rested?

Today, Jay welcomes renowned neuroscientist, sleep expert, and bestselling author Dr. Matthew Walker to unpack the profound importance of sleep and how it shapes every facet of our health and wellbeing. Bestselling author of Why We Sleep, Dr. Matthew Walker brings scientific rigor and heartfelt clarity to one of the most misunderstood and underestimated aspects of our lives.

Matthew opens the discussion by challenging the myth of the 'eight-hour rule.' While the average adult does best with seven to nine hours of sleep, the focus quickly shifts beyond just duration. Instead, Matthew introduces a more holistic four part framework—Quantity, Quality, Regularity, and Timing, or QQRT. This framework highlights how sleep is not simply about how long one sleeps, but also how deeply, how consistently, and how well it aligns with our natural biological rhythms.

Jay and Matthew's conversation also tackles common disruptors of restorative sleep, including caffeine, alcohol, and excessive exposure to artificial light. Dr. Walker discusses how these elements can interfere with the brain’s ability to enter deep and REM sleep, the latter being especially important for emotional processing, hormonal regulation, and memory consolidation. Sleep, it turns out, influences far more than individual health. 

In this interview, you'll learn:

How to Know If You’re Getting Enough Sleep

How to Improve Sleep Using the QQRT Formula

How to Align Your Sleep With Your Body’s Internal Clock

How to Avoid Waking Up Tired Every Morning

How to Optimize Your Evening Routine for Better Sleep

How to Fall Back Asleep After Waking Up at Night

How to Diagnose Sleep Apnea at Home

With scientific insight and practical wisdom, the episode paints a vivid picture of how sleep, when prioritized and protected, can serve as a catalyst for healing, clarity, and sustainable energy.

With Love and Gratitude,

Jay Shetty
