It’s not just a matter of feeling tired; over the long run, sleep deprivation can contribute to depression, obesity, diabetes, stroke, heart attack, Alzheimer’s disease, and cancer. “The silent sleep-loss epidemic is the greatest public health challenge we face in the 21st century,” argues Matthew Walker, PhD, of the University of California, Berkeley, in his new book, Why We Sleep. “Scientists such as myself have even started lobbying doctors to start ‘prescribing’ sleep.”
