Overview
- An international Lancet analysis of roughly 135,000 adults found that adding five minutes of moderate activity a day is associated with about 10% fewer deaths at the population level, rising to around 15% with ten minutes.
- Researchers stress these are population estimates from device-based observational data rather than prescriptions for individuals, with the largest gains projected for the least active groups.
- For people over 70, clinicians emphasize balance as a key predictor of healthy autonomy, with studies linking inability to stand on one leg for about 20 seconds to higher risks of stroke and premature death.
- Experts recommend simple balance drills, brisk walking and regular resistance training, noting meta-analyses that tie about one hour of strength work per week to roughly 25% lower mortality.
- Activity variety and socially engaging sports such as racket games or dance are associated with added benefits, though authors caution the evidence shows links rather than proven causation.
