Overview
- New explainers republished by The Independent and coverage in Business Today stress that biological age, not just years lived, better predicts health and longevity.
- Research cited includes reports that an eight‑week exercise program cut biological age by about two years and that healthier eating patterns slowed ageing by an average of 2.4 years.
- Sleep quality correlates with slower ageing, while large UK data link shift work—especially nights—to roughly a one‑year higher biological age compared with standard hours.
- Habits such as smoking, vaping and alcohol use are consistently tied to accelerated ageing, with one study of 8,046 adults associating any alcohol intake with faster biological ageing.
- At‑home saliva epigenetic tests are now widely marketed, and a Daily Mail feature highlights a company‑linked NAD+ supplement claiming a 1.26‑year reduction in 28 days, a result based on limited, commercially affiliated evidence.
