Psychological health is increasingly recognized as a fundamental cornerstone of overall well-being. In recent years, everyday lifestyle behaviors, specifically how we move and what we eat, have emerged as some of the most powerful, modifiable determinants of mental health. The growing fields of nutritional psychiatry, exercise psychology, and lifestyle medicine have consistently highlighted the profound impact that physical activity, sedentary behavior, sleep quality, and dietary patterns exert on psychological outcomes, including depression, anxiety, chronic stress, and cognitive function.

Crucially, the influence of these lifestyle factors is not static. From early childhood development and adolescent transitions to adulthood stress management and cognitive preservation in older age, the interplay between movement, nutrition, and psychological health continuously evolves. Understanding these dynamic relationships across the lifespan is essential for developing targeted, age-appropriate preventative strategies and therapeutic interventions.

This Special Issue aims to provide a comprehensive, multidimensional overview of how movement behaviors and nutritional choices independently and synergistically shape mental health from infancy to late adulthood.

We encourage researchers to submit original research articles, including cross-sectional studies, longitudinal analyses, randomized controlled trials, and review studies. All submissions will undergo a rigorous double-blind peer-review process to ensure the highest academic quality.

We look forward to receiving your valuable contributions.
