The inescapable drive to sleep: Overlapping mechanisms of sleep and sedation

Common human experience is that a long period without sleep is unsustainable, and it is also detrimental to health and behavior. The powerful and primal urge to sleep after sleep deprivation is intense and seems inescapable. The longer we stay awake, the more we feel the need to sleep, and however much we resist, we will inevitably succumb. Although it is obvious what benefits derive from other common and strong physiological drives, such as hunger, sex, and thirst, it is less obvious what drives us to sleep and what benefits accrue. Understanding the biochemical or circuit basis for the sleep drive could enable the benefits of sleep to be artificially stimulated with a new generation of sedative drugs.
