Non-24-Hour Sleep-Wake Disorder, also known as Non-24, is a rare circadian rhythm sleep disorder that affects the timing of an individual's sleep-wake cycle. This disorder is characterized by a persistent pattern of irregular sleep-wake cycles that do not align with the 24-hour day-night cycle.
Individuals with Non-24 experience a constant shifting of their sleep patterns, leading to difficulties in falling asleep and waking up at consistent times. This can result in chronic sleep deprivation, excessive daytime sleepiness, and impaired functioning in daily activities.

If you or someone you know is experiencing symptoms of Non-24-Hour Sleep-Wake Disorder, it is recommended to consult a healthcare professional for proper diagnosis and management strategies.
