Sleep is something akin to the ocean-it surrounds us, and we could not live without it, yet it remains a mystery, whose secrets we are only now beginning to unfold. Scientific research into sleep and dreams began in earnest about fifty years ago. Since that time, the small and burgeoning field of sleep medicine has taught us a great deal about how and why we sleep. This course will provide students with a comprehensive introduction to sleep and physiology, the evolution of sleep, circadian and biological rhythms, dreams, and the diagnosis and treatment of sleep disorders. Through exercises and assignments, students will learn the importance of sleep for mental and physical well-being and how to best establish a healthy sleep routine.
