Sleep patterns refer to the regular cycles of sleep and wakefulness that individuals experience. These patterns can vary significantly from person to person and are influenced by factors such as age, lifestyle, and overall health. Most adults require about 7 to 9 hours of sleep per night, while children and teenagers typically need more. During sleep, the body goes through different stages, including REM (Rapid Eye Movement) and non-REM sleep. Each stage plays a crucial role in physical restoration, memory consolidation, and emotional regulation. Disruptions in sleep patterns can lead to various health issues, including fatigue and decreased cognitive function.
