Big sleep + exercise win
A 53,000‑participant UK Biobank analysis found a 'SPAN' profile — 8–9.4 hours sleep, 42–104 minutes of moderate exercise and a high‑quality diet — is associated with about a 60% lower cardiovascular risk. The study also reports tiny changes matter: adding roughly 11 minutes of sleep alone was linked to a ~10% risk reduction. (x.com)
The peer‑reviewed analysis by Nicholas A. Koemel and colleagues was published 23 March 2026 in the European Journal of Preventive Cardiology. (academic.oup.com) The prospective cohort included 53,242 UK Biobank participants (median age 63.0 years; 56.8% male) and recorded 2,034 major adverse cardiovascular events over an 8.0‑year follow‑up — 932 myocardial infarctions, 584 strokes and 518 heart‑failure events. (academic.oup.com) Sleep and moderate‑to‑vigorous physical activity were derived from wearable data using a machine‑learning algorithm, diet was measured with a 10‑item diet‑quality score, and risk was modelled across 27 joint tertile combinations plus a composite SPAN score (0–100). (academic.oup.com) The study’s “optimal” SPAN combination corresponded to a hazard ratio of 0.43 (95% CI 0.30–0.62) versus the least favourable profile, while a median SPAN score was associated with HR 0.59 for major adverse cardiovascular events. (academic.oup.com) Authors emphasise the 10% lower‑risk figure represents a minimum combined change — an additional 11 minutes of sleep, 4.5 minutes of MVPA and a 3‑point rise in diet score (HR 0.90) — rather than the effect of 11 minutes of sleep alone. (academic.oup.com) Interaction analyses showed no evidence of synergistic effects between SPAN behaviours (RERI = 0.003; attributable proportion = 0.4%; synergy index S = 1.03), which the authors report indicates the behaviours’ associations with risk were essentially additive.
