Research & Science

Sleep is biological. It is also behavioral, environmental, social, and temporal.

Michael Grandner’s research examines sleep as a health behavior embedded in daily life. His work connects the causes and consequences of insufficient or poor-quality sleep with the development and implementation of interventions that can improve sleep and health.

A connected research program

From context to consequences to intervention.

Determinants and context

How social, behavioral, and biological factors shape sleep duration, insufficient sleep, and poor sleep quality.

Health and functioning

How habitual sleep duration and insufficient sleep relate to cardiovascular, metabolic, and behavioral outcomes.

Intervention and implementation

How behavioral interventions can address sleep as a health behavior and move evidence into practice.
