📄 Abstract
Nidra (sleep) is a fundamental physiological process that plays an important role in maintaining homeostasis, the body's ability to preserve a stable internal environment. In Ayurveda, Nidra is described as one of the Trayopastambha (three supporting pillars of life), along with Ahara and Brahmacharya1. Proper sleep is considered essential for bala (strength), pushti (nourishment), sukha (happiness), and overall health2. From a modern physiological perspective, sleep is a dynamic process involving coordinated changes in the nervous, endocrine, metabolic, and immune systems. During sleep, the body regulates energy metabolism, body temperature, cardiovascular activity, hormonal secretion, immune responses, and neural functions. Sleep also supports memory consolidation, tissue repair, and restoration of physiological functions. The interaction between sleep homeostasis and the circadian rhythm determines the timing and duration of sleep. Disturbances in sleep may disrupt metabolic, hormonal, immune, and psychological equilibrium, thereby affecting overall homeostasis. Therefore, understanding Nidra through both Ayurvedic and modern perspectives highlights its crucial role in maintaining physiological balance, promoting health, and preventing disease.
