sleep-wake
Biological rhythm pattern
Sleep-wake describes the cycle or pattern of alternating between sleeping and waking states.
The term appears in medical and scientific contexts: sleep-wake disorders, circadian sleep-wake rhythm.
It treats the two states as a unified system rather than opposites: The medication disrupted her sleep-wake cycle.
