According to the Center for Disease Control, 80 million adults in the United States suffer from chronic sleep deprivation, getting fewer than seven hours of sleep per night. There are many reasons for poor sleep — too much screen time before bed, stress, depression, poor diet and lack of exercise, to name a few.
Why is sleep important? It isn’t just about rest. While our sensory awareness, voluntary muscles and conscious thought do “sleep,” other parts of our bodies are busy rebuilding muscle and bone, mending skin, replenishing energy stores and even healing disease.
