Circadian Rhythm Phase Disorders

a group of sleep disorders involving sleep disruption that is primarily due to a mismatch between an individual's sleep-wake pattern and the pattern that is desired or required.

The disruption may be caused by:

a naturally occurring change or a malfunction of biological mechanisms or processes regulating the sleep–wake cycle
a mismatch between an individual’s sleep–wake cycle and the sleep–wake schedule required by their school, work or social schedule
a mismatch between an individual’s sleep–wake cycle and the day–night cycle of their physical environment.
