The Science Behind a Good Night's Sleep
Chasing Life
Nov 29, 2022

We all know sleep is vital, so why do many of us still find it so difficult to prioritize? CNN Chief Medical Correspondent Dr. Sanjay Gupta speaks with sleep scientist Rebecca Robbins about why we sleep in the first place and how to ensure we get a good night’s rest. And neurologist Ying-Hui Fu explores the latest research surrounding sleep, including what regulates the amount of sleep we actually need and what role genetics might play. We also meet Cliff Luther, a man who only needs about four hours of sleep a night yet wakes just as well rested as the rest of us. What’s his secret? This episode originally aired in June 2021.
