Dinacharya and Ritucharya for Community Health Promotion: A Classical Review With Contemporary Evidence

Background: The rising global burden of non-communicable diseases (NCDs) and lifestyle disorders has increased the need for sustainable and preventive health strategies. Ayurveda describes Dinacharya (daily regimen) and Ritucharya (seasonal regimen) as foundational approaches for maintaining health and preventing disease, with principles that align with modern concepts of chronobiology and preventive medicine. Objective: To critically analyse the concepts of Dinacharya and Ritucharya from classical Ayurvedic texts and evaluate their relevance in the context of contemporary biomedical and public health evidence for community health promotion. Methods: This narrative (classical) review was based on primary Ayurvedic texts, including Charaka Samhita, Sushruta Samhita, and Ashtanga Hridayam. Relevant modern literature was retrieved from databases such as PubMed, Scopus, DHARA, and WHO reports (1990–2026), focusing on circadian rhythm, lifestyle medicine, immunology, and preventive healthcare. Results: Key Dinacharya practices such as early rising, oral hygiene, oil massage, physical activity, and meditation show correlation with circadian rhythm regulation, stress modulation, and metabolic health. Ritucharya principles demonstrate alignment with seasonal variations in immunity, metabolism, and environmental adaptation. These practices collectively support prevention of major NCDs, including cardiovascular diseases, diabetes, respiratory conditions, and mental health disorders. Conclusion: Dinacharya and Ritucharya provide a practical, cost-effective, and culturally adaptable framework for community health promotion. Their integration into public health systems and wellness programs offers significant potential for preventive healthcare and warrants further implementation research.
