Because we're tired, of course. But for scientists, the curious thing about adult humans napping is that we are one of the very few species that rely on a single sleep period (monophasic) rather than napping periodically throughout the 24-hour cycle (polyphasic). Researchers in sleep, circadian rhythms, neuroscience, physiology, psychology, and chronobiology, present 16 studies from the Workshop on Polyphasic and Ultrashort Sleep-Wake Patterns, in Castello di Gargonza, Italy, May 1988. They discuss the evolution, development, and regulation of the sleep-wake cycle in animals and humans, as well as its circadian and ultradian components; and the effect of polyphrastic and ultrashort sleep on performance and their role in sleep disorders. Of interest to sleep researchers and neuroscientists, and to industrial psychologists, ergonomists, and other interested in designing efficient work-rest schedules.
