A Review on Nidra: Understanding It Through the Lens of Vega

Abstract Introduction: Sleep is a crucial biological function, occupying nearly one-third of a human's life. It is essential for physical, mental, and emotional well-being, offering the body an opportunity to rejuvenate. Modern lifestyles often neglect sleep, despite its importance, posing risks to health. Materials & Methods: This review explores the concept of nidrā in Ayurveda, specifically in the context of Aṣṭāṅgahṛdaya. Ayurveda texts were examined for references to sleep’s role in balancing the tridoṣa, focusing on conditions like anidrā and jāgaraṇa. Results: In Ayurveda, nidrā is regarded as one of the three pillars of health alongside food and celibacy. Improper sleep patterns lead to the vitiation of doshas, with vāta aggravated by anidrā, and kapha and pitta imbalanced by divāsvapna. Treatments for sleep disorders, such as nasya and dhūmapāna, are suggested at specific times to enhance efficacy. Discussion and Conclusion: Both ancient Ayurveda and modern scientific perspectives emphasize sleep's essential role in health maintenance. Improper sleep patterns are linked to various health disorders, and balancing sleep is critical for overall well-being and disease prevention. Ayurveda’s comprehensive understanding of nidrā complements modern health principles, highlighting the importance of restoring proper sleep habits to maintain physical, mental, and emotional health.
