We all know that we should get more sleep. That we should turn off our phones, our tablets, our TVs. That we should unwind and relax into seven to nine hours of slumber. But actually understanding why we need sleep — and internalizing why it’s so vital — can be more difficult. In this video, Matt Walker breaks down the science of sleep in a way that you can’t ignore.

“Sleep is your life-support system and Mother Nature’s best effort yet at immortality, says sleep scientist Matt Walker,” the video explains. “In this deep dive into the science of slumber, Walker shares the wonderfully good things that happen when you get sleep — and the alarmingly bad things that happen when you don’t, for both your brain and body. Learn more about sleep’s impact on your learning, memory, immune system and even your genetic code — as well as some helpful tips for getting some shut-eye.”
