The evidence, for clinicians and care teams
Sleep health is multidimensional.
Duration matters, but it is not the whole picture. Quality, timing, regularity, daytime function, and the absence of untreated sleep disorders all contribute to healthy sleep.
Evidence and application
Established science. A practical clinical framework.
Professional organizations use different models for different purposes, but they converge on a broader view of sleep.
CircAlign uses an independent four-part framework, Quantity, Quality, Consistency, and Clock Alignment, to organize relevant information for clinical review.

Specialty sleep care and whole-person care are complementary.
A sleep-medicine referral is the right path for diagnostic evaluation and treatment. Broader sleep and circadian patterns still interact with movement, nutrition, stress, metabolic health, and daily routines, the areas the primary clinic already coordinates.
