Importance of Nidra

Ayurveda; an eternal system of medicine, is known for its multidimensional approach towards mankind. Utility of this science starts from fertilization till death. Health of a person means healthy physical body and mind together. Ayurveda helps in keeping balance, harmony and equilibrium in all physiological activities of body and mind. Sleep is important because it affects our mental, physical, and emotional well-being. Sleep is defined as a state of unconsciousness from which a person can be aroused. In this state, the brain is relatively more responsive to internal stimuli than external stimuli. Sleep is essential for normal, healthy functioning of the human body. When the mind gets exhausted or become inactive and the sensory and motor organs become inactive then the individual gets sleep. During sleep different kinds of dreams will be seen. Sleep was born at the time of commencement of the creation of the universe only, out of tamas. Sleep is another form of tamas and manifests due to the predominency of tamas generally in nights.
