Breathwork Buzz vs. Evidence: The Science Behind Its Claims and Risks

Breathwork has exploded as a wellness trend, with some techniques easing stress and others promising transformative outcomes. While slower breathing can lower cortisol and rapid methods like Wim Hof may affect CO2/oxygen balance and inflammation, the evidence is mixed and often overstated. Experts warn that many courses charge high fees for claims not yet grounded in solid science, and that breathing is free and best guided by medical advice in risky cases. The takeaway: breathwork can have real effects, but hype should be tempered by evidence and safety considerations.
