He uses this TED Talk to explain the benefits of sleep. “We know this from epidemiological studies across millions of individuals. There's a simple truth: the shorter your sleep, the shorter your life. Short sleep predicts all-cause mortality,” he says.
“And if increasing your risk for the development of cancer or even Alzheimer's disease were not sufficiently disquieting, we have since discovered that a lack of sleep will even erode the very fabric of biological life itself, your DNA genetic code,” Walker added.
He notes that “There is simply no aspect of your wellness that can retreat at the sign of sleep deprivation and get away unscathed. It's rather like a broken water pipe in your home.”
“Sleep loss will leak down into every nook and cranny of your physiology, even tampering with the very DNA nucleic alphabet that spells out your daily health narrative.”
