Sleep Staging
Sleep staging is the process of categorizing the different phases of sleep throughout the night. It involves dividing sleep into stages—usually light sleep, deep sleep, and REM (Rapid Eye Movement) sleep—based on specific brain activity, eye movements, and muscle tone measured during sleep studies. These stages serve important functions for physical and mental health, such as memory consolidation and tissue repair. Sleep staging helps doctors understand sleep quality and diagnose disorders like sleep apnea or insomnia, providing insight into how well you rest and rejuvenate during the night.
