Students in Emory’s “Science of Sleep” class spent the semester analyzing research that suggests inadequate sleep may hinder their cognition and memory for finals, affect their mood and, over time, could create significant health problems.

Habits that promote sleeping well regularly are known as sleep hygiene. And the Emory Sleep Center, an interdisciplinary facility focused on sleep medicine, sees sleep hygiene issues so often that sometimes they are the sleep disorder in question, says Dr. Nancy Collop, the center’s director.
