“Not until the late 1800s did segmented sleep arouse medical concern in the West. By then, sleep had become consolidated and compressed, a consequence both of the growing pervasiveness of artificial illumination (first gas, then electric), which reconfigured the human body’s circadian clock, and of a heightened emphasis on efficiency and productivity born of the Industrial Revolution.”
—A. Roger Ekirch, Segmented Sleep

“…preindustrial sleep…was segmented. Unlike the seamless slumber we strive to achieve, sleep once commonly consisted of two major intervals, a “first sleep” and a “second sleep,” bridged after midnight by an hour or more of wakefulness in which people did practically everything imaginable.”
