The Role of Holistic Lifestyle Interventions (Mindfulness, Nutrition, Sleep Optimization and Traditional Therapies) in Improving Stress-Related Disorders and Quality of Life: A Systematic Review

Abstract

Stress-related disorders are increasingly associated with reduced psychological well-being, impaired sleep, poor physical
health, and diminished quality of life. Although conventional medical and psychological approaches remain important, many
individuals require accessible, preventive, and lifestyle-oriented strategies that can support long-term stress regulation
without relying heavily on clinical infrastructure. This systematic review examines the role of holistic lifestyle interventions,
including mindfulness, nutrition, sleep optimization, and traditional therapies, in improving stress-related disorders and quality
of life. The review focuses on evidence from peer-reviewed studies indexed in major academic databases, including Web
of Science, Google Scholar, PubMed, and related healthcare sources. It evaluates intervention types, target populations,
outcome measures, mechanisms of action, and implications for integrative medicine practice. The review is structured
around key outcomes such as perceived stress, anxiety symptoms, sleep quality, emotional regulation, physical well-being,
and overall quality of life. Findings are expected to show that mindfulness-based practices, dietary improvement, structured
sleep routines, and selected traditional therapies can contribute to stress reduction and improved well-being, particularly
when delivered through patient-centered and low-cost wellness models. The article also highlights the relevance of these
interventions for holistic wellness practitioners, primary care education, community health programs, and integrative
healthcare systems. However, variations in study design, intervention duration, measurement tools, and cultural context
suggest the need for stronger standardized protocols and long-term comparative studies.
