Easier breathing, better lung function, and healthier airways.
Start Here the foundations
Breath Moderate
The best-evidenced self-directed breathing lever. Breathing exercises (mostly yoga breathing) improved asthma quality of life ~0.42 on the AQLQ across trials; adding Bhramari pranayama left 68% of children controlled vs 39%; in a 43-trial COPD network meta-analysis yoga breathing ranked highest for quality of life. Free, teachable. Key limit: it improves symptoms and quality of life, not lung function (FEV1); see overGradedTiers. Cost

Supplement Moderate
NAC 600 mg twice daily cut COPD exacerbations ~22% over a year (PANTHEON, Zheng 2014, PMID 24904996), best in more symptomatic patients. Honest pairing: at 600 mg once daily it did NOT slow lung-function decline over three years, so it is an exacerbation-reducer, not a disease-modifier. Cheap, well-tolerated. Cost

In COPD, tai chi added ~98 feet (30 m) to a six-minute walk, a clinically meaningful gain, while training breath control, posture and gentle exertion. A good accessible on-ramp to pulmonary-rehab-style exercise (see completeness). Cost

Baduanjin ranked top for FEV1 lung function among Chinese exercises in stable COPD (a network-meta ranking, so treat the ranking cautiously; see overGradedTiers). Gentle, standardized eight-movement set, easy to learn. Cost

Levers with real evidence for breathing & lungs. Tiers are the strength of that evidence, not our endorsement. An up arrow raises the goal; a down arrow is a reduce-lever.
Evidence strength
How confidently the research supports a claim. Strength describes the evidence, not our endorsement.
StrongLarge or repeated randomized trials point the same way (a firm "no effect" counts too).
ModerateGood trial evidence, but fewer, smaller, or less consistent studies.
EmergingEarly trials or pooled signals, real but not yet settled.
PreliminaryMostly indirect, animal, or observational evidence.
Risk or overturnedEvidence of risk, or a claim the trials have since reversed.
