The connection between stress and hormones
The nervous system and the endocrine (hormone) system are deeply intertwined. When you are in a chronic state of "fight or flight," your body prioritizes the production of cortisol and adrenaline. It does this at the expense of reproductive hormones like estrogen and progesterone. This is a survival mechanism — your body assumes that if you are running from a tiger, it is not the right time to reproduce or repair tissue.
To balance your hormones naturally, you must first signal safety to your nervous system. Only when the nervous system down-regulates can the endocrine system resume its normal, balanced function.
The therapeutic yoga approach
In the Iyengar tradition, we use specific asanas to directly influence the endocrine glands and the autonomic nervous system. As Dr. Geeta S. Iyengar extensively documented, the practice is a powerful tool for hormonal regulation.
"Wherever space and stillness is created, prana flows." — B.K.S. Iyengar
Key practices for hormonal regulation
According to the lineage texts, the following practices are foundational for supporting the endocrine system:
Inversions: Poses like Sarvangasana (Shoulder Stand) and Sirsasana (Headstand) are unparalleled in their ability to balance the hormonal system. They bathe the thyroid and pituitary glands — the master controllers of the endocrine system — in fresh blood, optimizing their function and sending messages of calm to the parasympathetic nervous system.
Yoga and functional nutrition go hand in hand for hormonal balance — especially with chronic conditions where there is often inflammation. If we can calm the inflammation, we can make everything feel better with the yoga.
Supported Backbends: Setu Bandha Sarvangasana, often referred to by B.K.S. Iyengar as a "boon to humankind," benefits all systems of the body. It stimulates the vagus nerve and creates profound relaxation, shifting the body out of stress and into repair mode.
Pranayama: Yogic breathing techniques, such as Ujjayi and Viloma, are the primary tools for nervous system regulation. They relieve psychological distress, reduce anxiety, and create the internal environment necessary for hormonal balance.
Integrating functional nutrition
While therapeutic yoga creates the neurological environment for healing, functional nutrition provides the physical building blocks. Hormones are synthesized from fats and proteins. If your diet is lacking in essential nutrients, your body cannot produce the hormones it needs, regardless of how relaxed you are. A holistic approach combines the structural and neurological benefits of yoga with the targeted nourishment of functional nutrition.
