Role of Nidra in the Modulation of Ageing Processes: An Ayurveda Perspective

Introduction: Sleep is a vital component of life. It is a dynamic brain activity that arises from the interaction of two fundamental systems, the circadian rhythm and the homeostatic desire to sleep, rather than a passive condition of unconsciousness. Ayurveda has identified Nidra (Sleep) as one of the three main pillars of health (Trayopastambha), and such sleep is considered the necessary solution to all aspects of physical, emotional, and mental well-being. In 1999, the World Health Organisation designated the year as the International Year of Older Persons (IYOP), marking a significant turning point in global awareness and action toward the challenges faced by older people. Since then, ageing and age-related health issues have gained significant international attention. Currently, there is a growing global interest in understanding the ageing process and improving the quality of life for older adults. Projections indicate that by the mid-21st century, the old-age dependency ratio will be doubled in more developed countries and triple in less developed regions, posing substantial social and economic challenges. This presents an opportune moment to delve into the potential of Ayurveda, which offers promising approaches to enhance longevity & delay ageing. Results & Discussions: Nidra acts as a highly effective Rasayana (rejuvenator), a supporting pillar for health, longevity, and delayed ageing. Ayurvedic knowledge on Nidra as a supreme rejuvenator and its role in delaying the ageing process is captured in this review study. Good quality sleep in an appropriate amount helps repair tissues, balance hormones, and prevent degenerative changes. From a contemporary perspective, sleep promotes cellular regeneration, enhances immunity, and reduces oxidative stress factors that are directly associated with ageing. This research paper highlights the physiological and therapeutic significance of Nidra in slowing down the ageing process. Conclusion: Nidra is the basis of whole-body restoration and slowing the ageing process.
