Sleep influences many parts of health and everyday functioning. Christine Won, a sleep specialist who began studying sleep after taking an undergraduate course called "Sleep and Dreams," explains how stress and sleep interact. She returned to undergraduate teaching and now runs a popular course called "Mystery of Sleep."
Won describes basic sleep functions: restorative processes for the body, emotional regulation, and memory consolidation. She explains that stress can interrupt these processes and reduce sleep quality, which in turn harms mood and memory. In public remarks she offers top tips for getting a good night’s rest and links those tips to how sleep supports health.
Her work at Yale combines clinical leadership, research, and teaching, and her career shows how an early class shaped a focus on sleep medicine.
