The six main pillars of this specialty include physical activity, nutrition, stress resilience, cessation or risk reduction of substance use, quality sleep, and connectivity. Lifestyle Psychiatry: Through the Lens of Behavioral Medicine is grounded in the same pillars, drawing upon theories, methods, and empirical findings from health psychology and behavioral medicine. Lifestyle psychiatry is a rapidly emerging area within healthcare informed by rigorous research within the social and biological sciences, public health, and medicine. A volume in the Lifestyle Medicine series, this book uses a comprehensive biopsychosocial approach to prevent and treat psychiatric disorders and promote mental and physical well-being through evidenced-based lifestyle interventions. Draws upon theories, methods, and empirical findings from health psychology and behavioral medicine. Provides evidence-based research on the bi-directionality of mental and physical health.
