How Sleep Rewires Your Brain, Balances Your Hormones & Extends Your Life | Dr. Matthew Walker

We all know sleep is important, but most of us don’t realize just how much it shapes our health—from metabolism and heart function to emotional well-being and even social connections. In this episode of The Dr. Hyman Show, I sit down with world-renowned sleep expert Matthew Walker, PhD, to uncover the science behind why sleep is one of the most powerful (and overlooked) tools for longevity.

In this fascinating conversation, we discuss:

• Why Dr. Walker sees sleep as the foundation of good health and how it enhances the benefits of diet and exercise.
• The dramatic effects of even mild sleep deprivation on cognitive function and emotional health.
• How poor sleep can disrupt blood sugar regulation and increase the risk of chronic disease.
• The science behind deep sleep and its role in memory, learning, and brain detoxification.
• Simple, science-backed strategies to improve your sleep quality starting tonight.

If you’ve ever struggled with sleep—or just want to optimize your health—this is an episode you won’t want to miss.
