For controlling your hypertension, there are two effective yoga exercises that helps lower the blood pressure:
Inverted yoga reverses the action of gravity on the body. The most profound changes brought about by Inverted Yoga is in circulation. In inverted poses, legs and abdomen are placed higher than the heart.
Lengthening up through the legs and keep them very active so your spine opens and the entire body actively involved in the pose.
One of the reasons for this is simply because the force of gravity is reversed and venous return becomes significantly greater.
Normally, the muscles of the calf and other skeletal muscles in the lower extremities must contract in order to pump unoxygenated blood and waste back to the heart through the veins.
In inverted poses, gravity causes the blood to flow easily back through the veins and this brings the blood pressure in the feet to a minimum. This in effect gives skeletal muscles a chance to rest.
In Inverted poses, drainage of blood and waste from the lower body back to the heart is increased and disorders such as varicose veins and swollen ankles are relieved.
