Polysomnography (PSG) is a comprehensive sleep study that records brain activity, eye movements, muscle activity, heart rhythm, and breathing patterns to diagnose sleep disorders. Its clinical relevance lies in guiding treatment for conditions such as obstructive sleep apnea, narcolepsy, and insomnia, making it a cornerstone of sleep medicine.
The Polysomnography (PSG) market size reached approximately USD 3.3 billion in 2025, and the market forecast projects a CAGR of 8.5% from 2026 to 2033, reflecting robust growth outlook driven by rising prevalence of sleep disorders, expanding reimbursement frameworks, and advances in home‑based monitoring technologies. This industry expansion encompasses diagnostic, home‑based, and portable PSG solutions across hospitals, sleep centers, and emerging tele‑health platforms.
