Headstand Posture--Sirasana
Sirsa means"head". Headstand has been called the king of asanas. It is an important posture, as it brings vitality and clarity to the brain and the mind. It is a healing and regulatory posture that conveys an abundant blood supply to the pituitary and pineal glands in the brain. Studies have shown that regular practice of the Headstand can increase the hemoglobin content of the blood.
The correct form for entering into and down out of the Headstand is with the legs together with muscles contracted and straight. One enters the position by pressing off the toes and descending on to the toes. It is a good idea to use a wall in the beginning as momentum can cause you to go past vertical . As you enter into the position, walk your toes as close to your head as possible. The closer you are to your head, the easier it is to lift the toes off of the floor. Once you are in headstand position, keep the shoulders lifting up away from the floor. Maximize the distance between the ears and shoulders. Keep the elbows in line with the shoulders. Abdominals are in tight.
Note of caution: This is not an easy posture. Students should try this only after they have been doing practice for some time. Develop strength in the arms and shoulders with the Sun Salutations. If you have questions as to whether or not the condition of your health allows for the practice of the Headstand, consult your physician.
