When it comes to preventing or curing a headache, there is no substitute for a thorough, daily yoga program. The following sequence offers poses that are helpful for opening the chest and stretching and relaxing the upper back and neck. Include them in your regular practice if you are prone to headaches and see if they help bring some relief and new awareness. Breathe deeply and slowly during all the postures and remember to relax the forehead, eyes, jaw, and tongue. The first part of the program is prevention, practiced when you do not have a headache. The second part, beginning with Supta Baddha Konasana, may be helpful in relieving a headache when it first begins. You will have better results if you start stretching and releasing at the first sign of a headache, before the muscles go into spasm.
