Sleep is a fundamental biological process critical for cellular repair, memory consolidation, hormone regulation, and immune function. Optimized sleep directly impacts metabolic health, cardiovascular risk, cognitive performance, and mood stability, thereby extending healthy lifespan by preventing age-related decline and disease. Chronic sleep deprivation accelerates biological aging and impairs overall physiological resilience.
