When a person has a headache, several areas of the head can hurt, including a network of nerves that extends over the scalp and certain nerves in the face, mouth, and throat. The muscles of the head and the blood vessels found along the surface and at the base of the brain are also sensitive to pain because they contain delicate nerve fibres. The bones of the skull and tissues of the brain itself never hurt because they lack pain-sensitive nerve fibres. The ends of these pain-sensitive nerves, called nociceptors, can be stimulated by stress, muscular tension, dilated blood vessels, and others trigger of a headache. Simple Yoga techniques can serve as an alternative or supplement to other remedies for dealing with headaches, as both prevention and treatment. A regular routine of Yoga exercises, breathing techniques, and relaxation/meditation can help prevent chronic headaches or reduce their severity. Exercises that stretch your muscles can release the tension that often causes headaches. Exercises that increase overall circulation and promote strength and balance are also helpful as they promote physical and mental balance and can strengthen your immune system. Yoga also helps to increase self-awareness, enabling you to address physical symptoms before they become severe. Eka Pada Sirsasana Eka means one. Pada is the leg. This variation of Sirsasana is done by lowering one leg to the floor in front of the head, holding the other leg up vertically. Sequence:
This is a difficult pose, so it may not be possible to touch the floor in the beginning. Gradually as the legs become more elastic and the back gets stronger, the legs will touch and then rest on the floor without loss of the head balance. This asana strengthens the neck and also the abdominal walls. The abdominal organs are contracted and made to function well. Inverted postures, or those where the head is lowered briefly, increase oxygen to the brain and can reduce headache-causing strain.
