Savasana or corpse pose gets its name from the recumbent posture of a dead body. It is a position of rest and relaxation, and is usually practiced towards the end of a yoga session.
Savasana is an asana of yoga practice lying on the back, the arms and legs are spread and the eyes are closed. The whole body is relaxed onto the floor with an awareness of the chest and abdomen rising and falling with each breath. The asana is released by slowly deepening the breath, flexing the fingers and toes, reaching the arms above the head, stretching the whole body, exhaling, bringing the knees to the chest and rolling over to the side and after a short time and a slow inhalation, the practitioner takes a seated position.
Savasana brings a deep, meditative state of rest, which may help in the repair of tissues and cells, and in releasing stress. It helps reduce blood pressure, anxiety, and insomnia.
