The thyroid is a gland located in the neck that's responsible for regulating the body's metabolism, or the rate at which it burns energy or fat for fuel. Hyperthyroidism, or an overactive or accelerated thyroid, produces excess amounts of the hormone called thyroxine, according to the Mayo Clinic. This hormone may cause side effects such as a faster and irregular heartbeat, jitters and even mood swings. Some exercises may help calm the thyroid and reduce symptoms, including yoga. Avoid high-intensity exercise until you know how your body reacts to various forms of exercise, and talk to your doctor about cautions.
The cat pose is a classic yoga position that's easy for most people to perform. The pose offers a variety of benefits, including increased circulation in the spine. Kneel on the floor, hands placed on the floor at shoulder level. Lean back, keeping the hands in place but lowering your buttocks to your calves. Return to the starting position and arch the back, exhaling as the back rounds toward the ceiling while you drop your head toward the floor. Inhale and reverse the move, creating a bend in your spine as your pelvis and stomach reach for the floor, lifting your head slightly. Perform this sequence of moves several times.
A fish pose may be easier to accomplish for starters. Lie on the floor, legs together, knees slightly bent. Place your hands slightly under your buttocks. Inhale, lifting the upper body from the floor while keeping the buttocks and the head touching the floor. Don't place a lot of weight on your head or neck. Hold the position for about 15 seconds and then relax. The fish pose helps flood blood-rich oxygen and other vital nutrients to the chest, head and neck, including the thyroid gland.
The bridge pose is also good for the thyroid, the brain and to relieve tired legs, suggests Yoga Journal. To perform the bridge pose, lie on your back on the floor, knees bent and arms at your sides. While you exhale, lift your buttocks and thighs off the floor, lifting the upper torso without lifting the shoulders or the head from the floor. Make sure you keep your knees directly over your heels and lift your pelvis toward the ceiling, sucking in the lower abdomen as you lift. Your arms, shoulders, head and neck should be relaxed. Hold this position for about 30 seconds and then relax.
