In Sanskrit ‘Śīrṣā’ means ‘head’. In yoga, Headstand is considered to be the ‘king of āsanas’ due to the remarkable benefits it brings to memory and concentration. Learning to balance upside down can bring you great confidence, but be sure to practice it carefully, only after you have studied all the information about the technique and contraindications.
The headstand is a boon for developing brain power and a healthy heart, and the beauty of it is that nearly anyone can do it. To the surprise of many people, it does not require any special strength or flexibility; all you need to do is respect certain basic considerations and follow the step-by-step guidelines given. Once you have learned it, it feels as natural to stand on your head as it does to stand on your feet.
Because of improper or tight clothing, many people experience a severe limitation of movement. This is true especially for the cervical region and the shoulder muscles. Neckties, tightly buttoned shirt collars and shoulder straps all exaggerate this condition. Tight pants can cause considerable havoc with blood circulation, breathing, and movements of the sacral and lumbar region, which can produce headaches and weaken the abdominal muscles. The postural defect is further enhanced by the modern tendency of spending long hours hunched over a computer, desk or car steering wheel. To derive maximum benefit, the Fish should follow immediately after the Shoulderstand. It relieves any congestion and cramp which may have been caused by the Shoulderstand.
