Sleep Medicine in Ancient and Traditional India

Abstract

In ancient India, as in other countries, people had shown great interest in understanding sleep and interpreting dreams. One can always find the emphasis being laid on deep sleep in ancient Indian literature. The Vedas, written about 2000 or more years before Christ are the chief sources of knowledge about sleep medicine in ancient India. These religious texts contain anatomical, physiological, psychological, pathological, and therapeutic views, which had found their reflection in the traditional Indian medicine, called Ayurveda. Though the entire wisdom about Ayurveda may not be available to us now, a good account of it is contained in Samhitas (encyclopedias) written by Charaka and Sushruta in 1000 BC. In Ayurveda, sleep is classified into seven types on the basis of its causative factors. In addition to several medications, Ayurveda does recognize prayer as one form of treatment, where the goddess of sleep Nidra devi is invoked to get sleep.
