One study on SKY Breath noted an increased release of prolactin and oxytocin, enhancing feelings of calmness.
The shift is not just “less stress hormones” but “more recovery/regulation hormones.”
Just a few minutes of rhythmic breathing can calm the mind in the moment.
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 cortisol. While this response is adaptive in acute situations, persistent cortisol elevation contributes to emotional exhaustion, sleep disturbance, and systemic inflammation.[1] Emerging research shows that SKY Breath can moderate these hormones, raising what we might call “well-being” and bonding hormones (prolactin, oxytocin) and lowering the chronic stress hormones. The result: a body better equipped to rest, recover, and resist.[7,8]
What does this look like in the endocrine system? When the brain perceives threat, the hypothalamus triggers the pituitary to release ACTH........
