Sleep

Sleep is a natural, recurring state of rest in which the body and mind are not active. It is essential for maintaining physical and mental health. During sleep, the body undergoes various processes that help restore energy, repair cells, consolidate memories, and regulate hormones. Sleep occurs in cycles, with stages including light sleep, deep sleep, and REM (rapid eye movement) sleep, each serving different functions, such as physical restoration and cognitive processing. Proper sleep is vital for overall well-being, helping with mood regulation, concentration, immune function, and overall cognitive performance. Lack of sleep can negatively impact health and daily functioning.
