Sleep and Brain Health

Sleep deprivation significantly impairs cognitive performance, leading to increased mistakes and longer task completion times. Imaging studies reveal that lack of sleep diminishes activity in the prefrontal cortex, responsible for decision-making, while the amygdala becomes more active, heightening emotional responses. Additionally, the brain's glymphatic system, crucial for clearing metabolic waste, operates at peak efficiency during sleep, underscoring its importance in preventing conditions like Alzheimer's disease.
