Body: Why we sleep

Why we sleep
Written by Matthew Walker
Amazing breakthrough - science has discovered a new treatment
Live longer
Enhances memory
More creative
Look more attractive
Makes slim
Lowers food cravings
Protects cancer and dementia
Wards off colds and the flu
Lowers risk of heart attacks and stroke and diabetes
Youll even feel happier, less depressed and less anxious
Neglecting sleep undercuts your creativity, problem solving, decision-making, learning, memory, heart health, brain health, mental health, emotional well-being, immune system, and even your life span.
Why do we sleep? After all, when you’re sleeping—and all animals do—you can’t hunt, gather, eat, reproduce, or defend yourself. Yet Walker concludes that the evolutionary upsides of sleep are far greater than these downsides. In brief, sleep produces complex neurochemical baths that improve our brains in various ways. And it “restocks the armory of our immune system, helping fight malignancy, preventing infection, and warding off all manner of sickness.” In other words, sleep greatly enhances our evolutionary fitness—just in ways we can’t see.
