Understanding Circadian Rhythm Sleep Disorders

The video discusses circadian rhythm sleep disorders, which occur when there's a mismatch between one's internal sleep-wake cycle and the external environment. It covers five types: delayed phase, advanced phase, non-24-hour, shift work, and jet lag. Delayed phase sleep disorder involves difficulty sleeping early, common in adolescents. Advanced phase sleep disorder causes early evening sleepiness, affecting social interactions. Non-24-hour sleep-wake disorder, often seen in blind individuals, results in a shifting sleep schedule. Each disorder presents unique challenges and impacts daily life.
