<p>The most credible programmes are built around validated biomarkers: telomere length, VO2 max, grip strength, inflammatory markers (particularly CRP and IL-6), and metabolic health indicators including glucose variability and insulin sensitivity.</p><p>The interventions with the strongest evidence base are not exotic. High-intensity interval training has more evidence for longevity benefits than almost any pharmaceutical. Time-restricted eating, in its simpler forms, is well-supported. Sleep optimisation remains the single highest-return intervention available.</p><p>What the best longevity retreats add is personalisation and measurement: a rigorous baseline assessment, a programme designed specifically for the individual's biological profile, and follow-up testing to evaluate what has changed.</p><p>The retreats that combine this clinical rigour with exceptional environment and hospitality are rare. They are also, typically, the most expensive. The cost-benefit calculation is one each individual must make for themselves.</p>
