A gentle, low-cost Chinese practice blending slow movement, breathing, and focused attention, easy for almost anyone to take up. The most consistent benefits are better sleep, lower stress and milder low mood, and improved balance and strength. Effects on blood pressure and inflammation are smaller and less certain; slowed aging is unproven. Very safe. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Resting blood pressure | < 120/80 mmHg | Tracks the modest blood-pressure-lowering effect |
| Resting heart rate | 50–70 bpm | Reflects autonomic balance and cardiovascular conditioning |
| Heart rate variability (HRV) | Higher is generally better (age-dependent) | A direct readout of autonomic flexibility, the proposed mechanism |
| hs-CRP | < 1.0 mg/L | Tracks chronic inflammation, a longevity-relevant target |
| Fasting glucose / HbA1c | Glucose 70–85 mg/dL; HbA1c < 5.3% | Relevant where metabolic benefit is a goal |
Cadence: Re-check at ~12 weeks, then every 6–12 months; functional and qualitative markers every 4–12 weeks.
