1. Stimulate Thyroid Function: Certain yoga poses are thought to stimulate blood flow to the thyroid gland, which may improve its efficiency.

2. Activate the Parasympathetic Nervous System: Yoga relaxes the body and activates the parasympathetic nervous system, which can help reduce stress. Stress is linked to thyroid issues, as cortisol hormones can interfere with the production of thyroid hormones

3. Improve Blood Circulation: Yoga poses involve compression and release of certain body parts, which enhances blood circulation. This "squeeze-and-release" effect can be beneficial for glands like the thyroid, aiding in their proper functioning.

4. Strengthen Neck and Throat: Yoga asanas  Ustlikerasana (Camel Pose), Setu Bandhasana (Bridge Pose), and Halasana (Plow Pose) involve stretching the neck and throat area, which can stimulate the thyroid glands.

5.  Practice Regularly and Mindfully: Consistency is key in reaping the benefits of yoga for thyroid health. Regular practice of yoga, combined with mindfulness and attention to the body's limitations, can lead to positive outcomes. However, yoga should not be considered a replacement for medical treatments or medications prescribed by your doctor.
