Immune Boost
Strengthen your immune system through breath-mediated nervous system regulation
The immune system and nervous system are in constant communication through the vagus nerve and the inflammatory reflex. Chronic stress suppresses immune function through sustained cortisol elevation, which inhibits white blood cell production and natural killer cell activity. Breathing exercises that activate the parasympathetic nervous system reduce cortisol and restore the immune-supportive environment that chronic stress disrupts.
The cholinergic anti-inflammatory pathway — activated through vagal stimulation during slow breathing — provides a direct link between breathwork and immune regulation. When the vagus nerve fires, it releases acetylcholine, which modulates the inflammatory response and prevents the immune-suppressing effects of excessive inflammation. Regular breathing practice keeps this pathway active and responsive.
Wim Hof-style breathing offers a different immune-boosting mechanism: controlled hyperventilation followed by breath retention creates a temporary stress response that, paradoxically, trains the immune system to respond more effectively. Research on the Wim Hof method shows that trained practitioners can voluntarily influence their innate immune response — though this represents an advanced practice and is not where beginners should start.

Frequently Asked Questions
Can breathing exercises actually boost immunity?
Yes. Research shows that regular breathing practice reduces cortisol, improves vagal tone, and activates anti-inflammatory pathways — all of which support immune function. The Wim Hof method specifically has been shown to influence the innate immune response in controlled studies.
Which breathing technique is best for immunity?
Daily coherence breathing for general immune support through cortisol reduction and vagal tone. For advanced immune training, the Wim Hof breathing method has the strongest research evidence for directly influencing immune function.
How often should I practice for immune benefits?
Daily practice is essential — immune benefits come from consistent vagal tone maintenance and cortisol regulation, not occasional sessions. A minimum of 5 minutes daily of coherence breathing is recommended for baseline immune support.
