What is Non-24?

Is your sleep cycle constantly shifting, leaving you feeling drowsy during the day or restless at night?
Non-24-Hour Sleep-Wake Disorder (Non-24) is a circadian rhythm disorder that causes a person’s sleep cycle to shift progressively later each day. Over time, this results in an irregular sleep pattern, making it difficult to maintain a consistent routine. Non-24 primarily affects individuals who are blind but can also impact sighted individuals.
