| The benefits of this posture, like the sarvanga-asana, are numerous. All of the muscles and ligaments in the calves and thighs are stretched resulting in greater leg flexibility. People suffering from leg cramps will find great relief from the hala-asana.
Since the abdominal area is contracted, blood compressed out of this area releases toxins and when the contraction is released the area is flooded with richly oxygenated blood. The contraction also helps to relieve gas and stimulates a sluggish digestive system. Similar effects take place as the neck and chest area is compressed effecting the throat, thyroid, parathyroid and lungs. Upper and lower back pain or discomfort is relieved due to the forward stretching of the spine.
It is highly recommended that this posture be accompanied by the sarvanga-asana. In fact, many of the benefits of the sarvanga-asana apply to the hala-asana as well with the added benefits detailed above.
The hala-asana is an excellent morning posture although some might find it more difficult then. During sleep the spine can become somewhat compressed resulting in the experience of tightness or stiffness in the back. A few repetitions of the hala-asana will quickly restore flexibility to the spine as well as promote alertness.
