Sleep is essential for overall well-being, allowing the body to relax and the brain to process information and form memories. During sleep, the hippocampus and neocortex collaborate to replay and integrate daily experiences, solidifying them into long-term memories. Lack of sleep can lead to serious health issues, such as hypertension, obesity, and diabetes, while also impairing cognitive functions, judgment, and motor skills. Research suggests that different sleep stages, like REM and deep sleep, play distinct roles in memory formation, though many aspects of this process remain unclear. Despite its critical role in survival and performance, many people struggle to achieve the recommended seven to nine hours of sleep each night.
