Sleep health is a multidimensional construct describing the adequacy and quality of sleep across several measurable dimensions: duration, continuity, timing, regularity, satisfaction, and daytime alertness. It frames healthy sleep as an active positive state that supports physical, metabolic, mental, and cognitive function, rather than merely the absence of a diagnosed disorder. Central to the concept is circadian regulation, the internal timekeeping that aligns the sleep-wake cycle with the day-night environment and coordinates hormonal, neural, and metabolic rhythms; neuromodulatory systems, including endocannabinoid signaling, participate in this control. Chronotype, meal timing, and behavioral patterns such as bedtime procrastination interact with this biology to shape when and how well individuals sleep, and psychosocial factors like loneliness and dietary exposures such as ultra-processed foods are increasingly implicated in disturbed sleep. Common disorders that erode sleep health include obstructive sleep apnea, marked by repetitive upper-airway collapse and often clustered with metabolic disease such as type 2 diabetes, and insomnia. The consequences of insufficient or disordered sleep extend to impaired cognition, mood disturbance, metabolic and cardiovascular risk, and poorer outcomes in aging populations, including fracture and recovery. Interventions span behavioral, nutritional, circadian, and therapeutic strategies aimed at restoring each dimension of healthy sleep.
