Sleep deprivation hormesis: The shift that doesn't kill you makes you stronger

Emergency medicine approximates a prehistoric human schedule. Our ancestors spent most of their time walking, socializing, relaxing, and conserving energy [1]. When motivated, they could sprint away from a tiger or toward a mammoth. Humans fasted for hours or days, then consumed large amounts of food when they found a beehive or large mammal. Primitive humans faced a range of discomfort in their environments. Without gas-powered furnaces, car air conditioning and safe homes, they frequently felt cold, hot, and tired.
