Exploration of sleep as it intersects anthropology, history, psychology, neurology, sociology, linguistics, and public policy. Topics range from normal sleep and circadian rhythms to the evolution of sleep and sleep habits around the world. Social determinants of sleep in the United States are considered. Students discuss racism and public policies in sleep health, the costs of massive societal sleep deprivation, the history and cultural narratives of dream interpretation, and principles of clinical sleep medicine. Open only to students in the Focus Program.
