Circadian Rhythm Disorders
topic
Circadian rhythm sleep-wake disorders are conditions in which the internal biological clock is misaligned with the desired or socially required sleep-wake schedule — including Delayed Sleep Phase Syndrome (DSPS, the inability to fall asleep before 2–4am or later), Advanced Sleep Phase Syndrome, Non-24-Hour Sleep Disorder, Shift Work Sleep Disorder, and Jet Lag Disorder — each producing difficulty sleeping at desired times and functioning at required times from an internal clock misaligned with external demands.
Role
Circadian rhythm disorders — particularly DSPS — are among the most mischaracterized conditions in clinical and educational settings: people with DSPS are routinely labeled lazy, undisciplined, or unmotivated because they cannot wake at socially required morning times, when in reality they have a diagnosable chronobiological disorder that is no more a character failing than color blindness. The majority of people with DSPS have spent years struggling with morning function without ever receiving an explanation or effective treatment — chronotherapy, strategic light therapy, and melatonin timing — that would address the actual circadian mechanism rather than the symptomatic failure to conform to conventional scheduling.
