Increase sleep duration

What this outcome means

Sleep duration is simply the total amount of sleep you get across the night, from first drifting off to your final wake-up. On DoseRank it maps to a defined health outcome built from human studies on total sleep time, hours slept per night, and consistency of that amount – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Chronically short sleepersPeople who routinely log far fewer hours than they need.

Shift and schedule strainWorkers whose hours cut the night short or shift it around.

Busy-life sleep debtAdults trading sleep hours for work, caregiving, or screens.
