'Sleep'

Sleep is a natural, recurring state of rest for the body and mind, characterized by reduced awareness and responsiveness to external stimuli. It plays a vital role in physical health, mental well-being, and cognitive function. During sleep, the body undergoes various processes, including muscle repair, memory consolidation, and hormone regulation. Sleep is divided into stages, including REM (rapid eye movement) sleep, which is important for dreaming and emotional processing, and non-REM sleep, which aids in restorative functions. Adequate sleep is essential for overall health, alertness, and quality of life.
