Abstract:
AbstractSleep is what we spend (or should spend) one third of our lives doing. Unfortunately, many individuals fall short of their biological need for sleep many nights of the week. The reasons for this are varied and include professional or personal obligations and social determinants, including loud noises or safety concerns in one's neighborhood. This article reviews the architecture of sleep; evidence for sleep health, including impacts of sleep health on mental and emotional health as well as cognitive function and performance; and strategies for improving sleep health.
