In this episode of The Human Upgrade, Dave Asprey dives into the global sleep crisis and reveals why mastering your sleep is the most important biohack you can do for your health, performance, and longevity.

First, sleep scientist Matthew Walker breaks down how sleep deprivation has become a global epidemic, slashing up to 20% of our sleep in the past century. He unpacks the dangers of too little sleep, including its direct link to increased mortality rates and cognitive decline, and discusses the optimal sleep duration for both quantity and quality. 

Next, Peter Martone shifts the conversation to sleep posture and environment. He shares simple yet effective techniques for optimizing your sleep position to maximize deep, restorative rest. Learn how a small change in your pillow or bed setup can lead to dramatic improvements in your sleep quality and overall health. 

Finally, Dan Gartenberg dives into the world of sleep biohacking. He reveals groundbreaking research on how sound waves can enhance your deep sleep and how controlling light exposure can unlock better rest. From sleep-tracking tech to environmental optimizations, Dan provides actionable tips to help you take your sleep game to the next level.
