Non-24-Hour Sleep-Wake Disorder

What is Non-24?

Non-24-Hour Sleep-Wake Disorder is a chronic circadian rhythm that causes your internal master clock to constantly cycle out of sync with the 24-hour day. If you’re struggling with cyclic insomnia and exhaustion, you are not alone.

Understanding the Shifting Clock

Unlike typical sleep struggles, Non-24 is a neurological misalignment of your circadian system, causing your internal or biological clock to drift progressively later each day.
The Constant 1-Hour Shift
The human brain relies on environmental light to reset our internal 24-hour cycle. Without this reset, the master clock drifts continuously, adding minutes or hours to the biological cycle every day.
Impact on Blind Individuals
Because light cues are missing, over 50-70% of people who are totally blind live with Non-24. Sighted individuals can also be affected due to biological insensitivity to light reset mechanisms.

Why Early Screening and Diagnosis is Critical

Leaving Non-24 unmanaged doesn't just disrupt your nights—it reshapes your entire life. Early clinical intervention offers a path to properly sync your circadian rhythm.
Prevent Chronic System Fatigue
Avoid long-term system breakdown and daily memory fogs caused by irregular REM sleep.
Reclaim Work and Relationships
Entraining your clock allows you to participate reliably in social and professional commitments.
Mitigate Mood & Anxiety Risks
Aligning biological neurotransmitter release helps manage depression and anxiety loops.
