The thyroid is one of the largest endocrine glands in the body. It is located in the neck, just below the Adam's Apple. The thyroid gland directs hormonal function and regulates metabolism. It produces and secretes hormones that influence almost every cell of the body. These hormones play a crucial role in burning fat.
Metabolism is the rate at which you burn calories; therefore by stimulating the thyroid gland you increase metabolism and the rate that you burn calories.
Many studies show that certain yoga poses help stimulate the thyroid gland. Yoga poses stretch, twist and compress the body, which has a positive effect on the entire endocrine system. This is done by improving blood flow to the glands as well as massaging them which aids in regulating their function. By simply turning the body upside down we allow blood to flow into the neck and head at a faster rate, which nourishes the thyroid on a cellular level.
