Sleep
Sleep is a naturally recurring state of mind and body, characterized by altered consciousness, reduced sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings. It is essential for health, supporting processes such as memory consolidation, immune function, and cellular repair. Sleep occurs in cycles, including rapid eye movement (REM) and non-REM stages. Most adults require 7–9 hours of sleep per night. Sleep disorders, such as insomnia and sleep apnea, can significantly impact well-being. For more information, see the Wikipedia entry on Sleep.
