claimSleep health comprises several measurable dimensions: sleep duration (total amount of sleep per 24-hour day), sleep continuity or efficiency (ease of falling asleep and returning to sleep), timing (placement of sleep within the 24-hour day), alertness/sleepiness (ability to maintain attentive wakefulness), and satisfaction/quality (subjective assessment of “good” or “poor” sleep).
