This column focuses on the psychological, behavioral, and epidemiological dimensions of lifestyle-related health. It welcomes studies examining how modifiable lifestyle factors, including physical activity, sedentary behavior, sleep, dietary patterns, social interactions, and other daily behaviors, influence mental health, cognition, psychological resilience, emotional regulation, stress, anxiety, depression, and well-being across different populations and life stages. The column also encourages research on underlying biological, psychological, and social mechanisms, as well as evidence-based prevention and intervention strategies from health psychology, behavioral medicine, exercise psychology, nutritional psychiatry, lifestyle medicine, and public mental health perspectives.
