Circadian Rhythm Sleep Disorders (CRSD) Market Expands as Light-Therapy Devices, Chronobiotic Treatments, and Home-Based Sleep Monitoring Gain Adoption

Keyword Definition
Circadian Rhythm Sleep Disorders (CRSDs) are conditions caused by a misalignment between an individual's internal biological clock and the external environment. Major CRSD types include:
• Delayed Sleep Phase Disorder (DSPD) - very late sleep-onset and wake times
• Advanced Sleep Phase Disorder (ASPD) - unusually early sleep and wake times
• Non-24-Hour Sleep-Wake Disorder - common in individuals with limited or absent light perception
• Irregular Sleep-Wake Rhythm Disorder
• Shift-Work Sleep Disorder
• Jet-Lag Disorder

Typical symptoms include insomnia, excessive daytime sleepiness, fragmented sleep, impaired cognitive functioning, and reduced quality of life.
Treatments generally include:
• Light therapy (morning bright light, dawn simulators)
• Melatonin and other chronobiotic agents
• Behavioral interventions, chronotherapy, and sleep-wake scheduling
• Supportive pharmacological agents when required

Market Size, Growth & Forecast
Different sources measure the market slightly differently (some focus only on treatment, others include diagnostics and devices). Based on synthesis of the most credible ranges:
• 2024-2025 global market size: USD ~2.3-2.4 billion
• 2034-2035 projected market size: USD ~4.3-4.5 billion
• Expected CAGR: ~6-7%
A smaller subset analysis focusing exclusively on "sleep treatment" reports ~USD 780-800 million in 2024 with a slower CAGR (~4-5%). When combining devices + diagnostics + therapy, the broader CRSD market consistently falls in the ~USD 2.3B range for 2024.
