Which statement is accurate regarding non-24 disorder?

The selected statement accurately reflects the nature of non-24 disorder, which is characterized by the inability of an individual's internal circadian rhythm to align with the 24-hour day due to a lack of sufficient light exposure. This misalignment often leads to significant sleep problems, including difficulties in both falling asleep and staying asleep, resulting in a cycle of disrupted sleep patterns that can affect daily functioning.

Individuals with non-24 may experience a shifting sleep schedule that can lead to insomnia, excessive daytime sleepiness, and overall disarray in their daily lives. Essentially, the underlying issue is that the individual’s biological clock does not conform to the conventional cycle of night and day, which in turn disrupts their sleep and wakefulness. This makes it crucial for those affected to seek interventions, as managing the condition is often necessary to restore a more regular sleep pattern and improve quality of life.
