 The headstand or sirsha-asana is perhaps the most well-known Yoga posture. Its benefits are many and is fully deserving of all its notoriety. Its physical and mental benefits derive both from emphasis on balance and the body's inverted position.
Before attempting the sirsha-asana beginners to Yoga should wait until they have mastered some of the more basic postures (such as the sarvanga-asana, dhanura-asana, ugra-asana, etc.). If you are attempting the headstand for the first time and you are alone we recommend you position yourself facing a wall with your knees about three feet from the wall. If you should lose your balance after lifting your legs you can use the wall for support to return gently from the posture.
The greatest physical benefits of the sirsha-asana are to the neck, spine and brain. Regular practice of this posture adds suppleness to the spine and increases the flow of blood to the brain. It enhances poise and balance and relieves stress and tension in the lower portions of the body.
The benefits of sirsha-asana are not only physical. The mental benefits are also plentiful. You will find that daily practice of the headstand enhances awareness, sharpens attention and improves the memory.
