What is a sleep study test?

A sleep study, or polysomnography, is a test designed to track and measure body functions while you sleep, helping to diagnose various sleep disorders like sleep apnea, restless leg syndrome, insomnia, and narcolepsy. During the study, sensors are attached to monitor brain waves, heart rate, breathing patterns, oxygen levels, eye movements, and muscle activity, providing a comprehensive view of how the body behaves during each sleep stage. The test can be performed overnight in a sleep lab, where a specialist closely observes and records any sleep disturbances, or at home using simpler equipment primarily to screen for sleep apnea. Afterward, a sleep specialist reviews the recorded data of a sleep study test in Delhi NCR

to understand irregularities in sleep cycles, breathing, or other factors that may reveal underlying sleep disorders. This process is vital for recommending treatments like CPAP (continuous positive airway pressure) therapy, medications, or lifestyle changes to improve sleep quality and overall health.
