We, as a society, have reached peak exhaustion, reports Vogue.

Along with good eating habits and exercise, sleep is critical for the optimal functioning of our biological systems, says Fariha Abbasi-Feinberg, M.D., the medical director of sleep medicine at Millennium Physician Group in Fort Myers, Florida. “It is one of the three pillars of health, and the ultimate necessity,” she continues. But the lack of it and longing for it have made it the ultimate luxury in our maxed-out culture. “Sleep is the most valued commodity there is, and you can’t buy it,” confirms Sara Ivanhoe, M.A., the director of yoga programs at the University of Southern California, where she teaches a course on sleep. “If it evades you, it is impossible to enjoy almost anything.”
