Cortisol is the body’s primary stress hormone, produced by the adrenal glands as part of the hypothalamic-pituitary-adrenal (HPA) axis. In healthy amounts, cortisol helps regulate energy levels, blood pressure, and metabolism. However, chronic stress can lead to persistently elevated cortisol levels, which may contribute to fatigue, anxiety, poor sleep, and hormonal imbalance.
Yoga has increasingly been studied as a therapeutic intervention for stress regulation because it combines physical movement, breathing practices, and mindfulness, all of which influence the nervous system.
A randomized controlled trial studying women at risk for stress-related health conditions found that an eight-week yoga intervention significantly reduced cortisol reactivity to stress in participants with elevated stress responses.
Similarly, research examining yoga interventions in students under high stress found that morning cortisol levels significantly decreased after three months of regular yoga practice, suggesting improvements in physiological stress regulation.
Other neuroendocrine research has suggested that yoga may reduce stress by restoring balance between the sympathetic (“fight-or-flight”) and parasympathetic (“rest-and-digest”) nervous systems.
Well-known physicians and researchers such as Dr Andrew Weil and Dr Herbert Benson have also emphasised the role of breathing and mind-body practices in activating the body’s natural relaxation response.
How Yoga Helps Regulate Stress Hormones
Yoga may support cortisol regulation through several mechanisms:
• Slow breathing activates the vagus nerve and parasympathetic nervous system
• Gentle movement reduces muscle tension and improves circulation
• Meditation practices calm the brain’s stress centres
• Relaxation techniques reduce chronic activation of the HPA axis
Over time, regular practice can help the body become more resilient to stress triggers.
What a 1:1 Yoga Therapy Session Focuses On
A private yoga therapy session in Marylebone focuses on calming the nervous system and restoring physiological balance.
Sessions may include:
Gentle therapeutic movement
spinal mobility
hip opening
supported backbends
Breath regulation
diaphragmatic breathing
extended exhale breathing
box breathing
Restorative yoga
supported poses such as legs-up-the-wall or reclining twists
Deep relaxation
guided body scan or yoga nidra
The goal of the session is not intense exercise but teaching the body how to move out of chronic stress patterns.
