sleep duration
Hours of rest
Sleep duration is the length of time spent sleeping, typically measured per night or over a 24-hour period.
The term appears frequently in health research and wellness contexts: Experts recommend seven to nine hours of sleep duration for adults.
It often implies a measurable quantity that can be tracked or optimized: My fitness app monitors my sleep duration.
