A study published in the American Journal of Lifestyle Medicine discusses how integrating multiple lifestyle factors (e.g., diet, exercise, stress management) leads to significant health improvements compared to focusing on a single aspect. (Ornish, D. et al., 2008. Intensive lifestyle changes for reversal of coronary heart disease. American Journal of Lifestyle Medicine, 2(1), pp.25-33.)

Research from the World Health Organization highlights that mental health and physical health are deeply interconnected, and addressing both simultaneously leads to better health outcomes. (World Health Organization. (2014). Mental health: a state of well-being.)

An article in the Journal of Holistic Nursing explores the benefits of holistic nursing practices that consider the physical, emotional, and spiritual needs of patients, demonstrating better patient outcomes. (Dossey, B.M., & Keegan, L. (2009). Holistic Nursing: A Handbook for Practice. Journal of Holistic Nursing, 27(4), pp.319-325.)

A review in BMC Complementary and Alternative Medicine examines the effectiveness of integrative medicine, which combines conventional medical treatments with holistic approaches, showing improved patient satisfaction and health outcomes. (Ventegodt, S., Andersen, N.J., & Merrick, J. (2003). Quality of life philosophy III. Towards a new biology: understanding the biological connection between quality of life, disease, and healing. BMC Complementary and Alternative Medicine, 3(1), p.1.)

A systematic review in Psychological Bulletin supports the idea that interventions addressing multiple components of lifestyle, such as cognitive-behavioral therapy combined with physical activity, are more effective in treating depression than single-component interventions. (Cuijpers, P., van Straten, A., & Andersson, G. (2008). Psychological treatment of depression: A meta-analytic database of randomized studies. Psychological Bulletin, 134(5), pp.659-640.)
