Those who practice yoga regularly often speak about how yoga not only feels good on the body but also creates a more positive state of mind. Many yoga practitioners even describe a “yoga high” or a feeling of “yoga bliss” after class.
These personal feelings of happiness and wellbeing are now being backed by researchers studying the effects that yoga and meditation can have on emotions, and the biochemistry behind these modalities.
The direct and indirect benefits of yoga have been long known in eastern cultures and traditions, yet more recently the benefits of yoga have been well-recognized in the west.During various forms of exercise, yoga and meditation endorphins are released within the body from the pituitary gland in the brain. This blissful or zen-like happy state can be highly pleasurable and explains why so many yogis continue to practice yoga and meditation. [1]
The Foundation of Yoga and Meditation
The origins of Yoga and Meditation are deeply rooted in the ancient traditions of India, tracing back over 5,000 years. Yoga, originally a spiritual practice aimed at enhancing the harmony between mind and body, has evolved over the centuries, incorporating a range of styles and disciplines.
Meditation, often integral to yoga practices, focuses on training the mind to achieve a state of tranquil awareness, offering profound insights into the nature of existence and inner self. These age-old practices were developed with the intention of promoting physical health, mental clarity, and spiritual growth, laying a foundation for a balanced and enlightened life.
Together, yoga and meditation form a holistic approach to well-being, emphasizing the interconnectedness of the physical, mental, and spiritual aspects of our nature.
Regulation of Brain Chemicals
The profound impact of yoga and meditation on the regulation of brain chemicals has been the subject of extensive research across various scientific disciplines. For instance, studies conducted by institutions such as Harvard University have elucidated how regular meditation practices can lead to structural changes in the brain, particularly in areas associated with memory, sense of self, empathy, and stress (Harvard Health Publishing, 2021). [2]
Similarly, research published in the Journal of Alternative and Complementary Medicine demonstrates that yoga can significantly lower cortisol levels, thereby reducing stress and its related symptoms (2020). These findings underscore the scientific basis of yoga and meditation as effective tools for enhancing mental health and cognitive functions, offering a tangible method to foster a balanced emotional state and improve overall well-being.
To further explore the nexus between yoga, meditation, and brain health, interested readers are encouraged to review articles and studies available through reputable academic databases such as PubMed and PsycINFO, where a wealth of peer-reviewed research highlights the myriad ways these practices contribute to the regulation of brain chemistry and the promotion of mental health.
Balancing Hormone Levels and the Endocrine System
The impacts on brain chemistry and mental health, yoga and meditation have also been associated with balancing hormone levels and positively influencing the endocrine system.
A pivotal study conducted by the University of California, Los Angeles (UCLA), found that regular engagement in mindfulness meditation practices can significantly reduce the levels of the stress hormone, cortisol, thereby benefiting the endocrine system's overall function (University of California, Los Angeles, 2019). [3]
This research points to the potential of these practices not only in moderating stress responses but also in harmonizing the body’s hormone levels, which play a critical role in regulating mood, growth and development, metabolism, and reproductive processes.
The UCLA study, published in the Journal of Clinical Endocrinology, provides a robust scientific framework for understanding how integrative practices like yoga and meditation can serve as non-pharmacological approaches to improving endocrine health and hormonal balance.
Yoga and The Autonomic Nervous System
Yoga's influence extends beyond the endocrine system, deeply engaging the autonomic nervous system (ANS), which controls our body's unconscious actions, such as heart rate and digestion. The ANS is divided into the sympathetic nervous system (SNS), responsible for the body's ‘fight or flight' responses, and the parasympathetic nervous system (PNS), which promotes ‘rest and digest' functions.
Research conducted by Harvard University reveals that regular yoga practice can lead to an increase in parasympathetic activity and a decrease in sympathetic activity, hence promoting relaxation and reducing stress (Harvard Medical School, 2020). This balance is crucial for maintaining homeostasis and overall well-being. [4]
Harvard's study, along with similar research from institutions like the National Institute of Mental Health and Neurosciences (NIMHANS), Bangalore, India, underscores yoga's potential as a therapeutic intervention for managing conditions associated with dysregulation of the ANS, such as anxiety and hypertension. [5]
These studies are accessible through academic journals and databases, providing a wealth of information on how yoga practices can modulate autonomic functions, offering a non-invasive method to enhance physical and mental health.

The Science Behind Yoga and Meditation: Physical and Mental Impact
The practice of yoga has been shown to induce a ‘relaxation response' in the body, through which the parasympathetic nervous system is activated. This response counters the stress-induced reactions of the sympathetic nervous system, leading to decreased blood pressure, improved digestion, and reduced heart rate, collectively contributing to an enhanced state of physical health.
The conscious connection between body, breath, and mind central to yoga and meditation practices is not only a testament to their holistic approach to health but also underscores the intricate interplay between our physiological and psychological processes. This symbiotic relationship, affirmed by scientific research, positions yoga and meditation as powerful tools for cultivating resilience, wellness, and a deeper sense of peace. [14]
