Physical Activity as a Mediator between Sleep, Mental Health, and Well-Being in Active Individuals

Abstract

The relationship between physical activity, sleep quality, and mental health is multifaceted and vital for maintaining overall well-being. Regular physical activity plays a crucial role in enhancing psychological health, improving sleep, and increasing life satisfaction. Exercise has been consistently linked to reduced symptoms of depression, anxiety, and stress while regulating sleep patterns. These effects occur through complex neurophysiological mechanisms involving neurotransmitter regulation, hormonal balance, and cognitive improvements. This chapter explores the mediating role of physical activity in the relationship between sleep and mental health, emphasizing its importance in promoting better well-being. The chapter highlights evidence from various studies demonstrating that physical activity can improve sleep quality, reduce mental health symptoms, and prevent the onset of psychological disorders. Special attention is given to specific populations such as athletes, students, and older adults, considering their unique needs and benefits from physical activity. It concludes with practical strategies for incorporating exercise into daily routines to break the cycle of poor sleep and mental health, offering a cost-effective, non-pharmacological intervention that supports both mental and physical health.
