Understanding Nidra and Nidranasha: A Comprehensive Ayurvedic Review

The concept of health (Swasthya) in Ayurveda is grounded on the three pillars (Upastambha): Ahara (food), Nidra (sleep), and Brahmacharya (self-restraint), collectively referred to as the "Tripod of Life." Of these, Nidra plays a significant role in maintaining physical, mental, and spiritual well-being. Sleep disruptions (Nidranasha) can result from poor lifestyle choices, mental stress, dietary changes, or psychological factors, leading to adverse effects on the body and mind. This study explores the etymology, definitions, physiology, types, and pathophysiology of Nidra and Nidranasha, as described in Ayurvedic texts, while highlighting its management strategies. Ayurvedic classics emphasize that balanced Ahara, restful Nidra, and disciplined living sustain life and promote overall wellness. Key words: Nidra, Nidranasha, Ayurveda.
