The Science of Breath Rewiring Stress via Hormone Regulation
Understanding how breathwork, specifically the Sudarshan Kriya Yoga – RP (also known as SKY Breath and related practices) regulates stress requires a look into its effects on the body’s hormonal and neuroendocrine systems. In addition to directly interacting with the sympathetic nervous system (which activates the body’s fight-or-flight response) and the opposite parasympathetic nervous system (slowing the body down, restoring calm, and supporting recovery, healing, and long-term resilience) as discussed in a previous post, breathing is also tied to other hormone-regulating systems.[1] Also key to this process is the hypothalamic–pituitary–adrenal (HPA) axis, which governs the release of stress hormones such as cortisol and adrenocorticotropic hormone (ACTH).[2] When chronically activated, this system can impair mood, immune response, and metabolic stability.[3,4] When looking at research on SKY Breath and how it interacts with these systems, it appears to restore balance by down-regulating stress hormones while enhancing those associated with recovery and emotional well-being, including prolactin and oxytocin.[5,6,7,8] Chronic stress initiates a predictable cascade: The hypothalamus signals the pituitary to release ACTH, prompting the adrenal glands to secrete …
