Brahma Muhurta Jagran as a Preventive Lifestyle Measures: An Integrative Review of Ayurvedic and Modern Perspectives

Background: Ayurveda places strong emphasis on daily routines (Dinacharya) for preservation of health and prevention of disease. Among these, awakening during Brahma Muhurta—the early pre-dawn period—is considered foundational. Contemporary biomedical sciences increasingly recognize the importance of circadian rhythm alignment for metabolic, neuro-endocrine, and mental health. AIM: To critically review the concept of Brahma Muhurta Jagarana as described in classical Ayurvedic literature and to correlate it with modern chronobiology and physiological mechanisms relevant to health promotion and prevention of non-communicable diseases. MATERIALS AND METHODS: Classical Ayurvedic texts including Charaka Samhita, Sushruta Samhita, Ashtanga Hridaya, and Ashtanga Sangraha were reviewed for references related to Brahma Muhurta and Dinacharya. Contemporary biomedical literature on circadian rhythm, melatonin, neuro-endocrine regulation, and autonomic balance was analyzed to establish integrative correlations. RESULTS: Ayurvedic texts consistently describe Brahma Muhurta as the optimal time for awakening, cognitive activities, and spiritual practices, provided digestion of the previous meal is complete. This period coincides with Vata-dominant Kala, promoting lightness, alertness, and efficient elimination. Modern studies demonstrate that early morning awakening supports circadian synchronization, favourable hormonal secretion patterns, autonomic balance, and improved mental clarity. Melatonin withdrawal, cortisol rhythm optimization, and parasympathetic predominance appear to mediate these benefits. Conclusion: Brahma Muhurta Jagran represents a scientifically relevant lifestyle intervention aligned with circadian biology. Its regular practice may contribute to metabolic regulation, mental well-being, and prevention of lifestyle-related disorders. Integration of this principle into preventive healthcare strategies may help mitigate the growing burden of non-communicable diseases.
