Sleep
Sleep is a natural, recurring state of rest essential for physical and mental health in humans and animals. It is characterized by reduced consciousness, limited sensory activity, and decreased muscle activity. Sleep consists of several stages, including rapid eye movement (REM) and non-REM phases, each serving distinct physiological functions. Adequate sleep supports cognitive performance, memory consolidation, immune function, and emotional regulation. Sleep deprivation can impair these processes, increasing risks for health problems such as obesity, diabetes, and cardiovascular disease. Sleep patterns and needs vary by age, individual health, and lifestyle.
