Breath of Life: The Respiratory Vagal Stimulation Model of Contemplative Activity

Gerritsen, R. J. S., & Band, G. P. H. (2018). Frontiers in Human Neuroscience, 12, 397.

This comprehensive review establishes the mechanistic link between controlled breathing and vagal nerve stimulation, explaining how breathwork directly activates the parasympathetic nervous system.

Physiology of long pranayamic breathing: neural respiratory elements may provide a mechanism that explains how slow deep breathing shifts the autonomic nervous system

Jerath, R., Edry, J. W., Barnes, V. A., & Jerath, V. (2006). Medical Hypotheses, 67(3), 566-571.

Explores the neurophysiological mechanisms by which pranayamic breathing techniques modulate the autonomic nervous system and promote relaxation.

The Effect of Diaphragmatic Breathing on Attention, Negative Affect and Stress in Healthy Adults

Ma, X., Yue, Z. Q., Gong, Z. Q., Zhang, H., Duan, N. Y., Shi, Y. T., Wei, G. X., & Li, Y. F. (2017). Frontiers in Psychology, 8, 874.

Demonstrates that diaphragmatic breathing significantly reduces cortisol levels and improves attention and negative affect in healthy adults.
