The Circadian Rhythm Sleep Phase Shift Disorder Handout is a practical, patient-friendly educational tool designed to help individuals understand this often misunderstood sleep condition. Circadian rhythm disorders occur when a person’s internal biological clock—responsible for regulating sleep and wake cycles—becomes misaligned with their external environment or daily obligations, such as school, work, or social activities.

This handout focuses on the most common presentations of phase shift disorders, including Delayed Sleep Phase Disorder (DSPD) and Advanced Sleep Phase Disorder (ASPD). It explains how these conditions differ from general insomnia, outlines the typical signs and symptoms, and helps readers recognize when their sleep difficulties may be due to a biological rhythm shift rather than poor sleep habits alone.

The resource is designed to be easy to read and apply. It includes sections on possible causes of circadian misalignment—such as inconsistent sleep schedules, screen time, light exposure, and shift work—and provides actionable recommendations to begin addressing the issue. Strategies include behavior and environment modifications like light management, bedtime routines, gradual schedule changes, and when to consider professional support.

This handout is ideal for use in clinical settings, school health offices, mental health practices, and sleep education programs. It can serve as a conversation starter between patients and providers and reinforce in-session education with clear take-home advice. It’s especially helpful for teens, young adults, and individuals with neurodevelopmental conditions, as they are more prone to circadian rhythm disruptions.

By providing accessible information and practical tips, this handout empowers individuals and families to better understand their sleep patterns and take proactive steps toward healthier rest and improved daytime function.
