Cinque minuti in più di esercizio fisico e 30 minuti in meno di seduta potrebbero aiutare milioni di persone a vivere più a lungo

**Article TLDR**

* Small lifestyle changes can yield significant population-level longevity benefits.
* An additional five minutes per day of moderate-intensity physical activity (e.g., brisk walking) is associated with an estimated 10% reduction in premature deaths.
* Reducing sedentary time by 30 minutes per day is associated with an estimated 7% reduction in all-cause mortality.
* Evidence is based on a large study of approximately 135,000 participants from the UK, US, Norway, and Sweden.
* The largest gains were observed among the least active 20% of the population making small increases in activity.
* Findings emphasize population benefits rather than individual exercise prescriptions.
* Independent experts described the analysis as a meaningful advance over prior research focused on rigid activity thresholds.
* Moderate activity includes everyday actions that slightly increase breathing and body temperature (e.g., brisk walking, housework, gardening).
* A separate study found that combined small improvements in sleep, physical activity, and diet were linked to longer life expectancy.
* For individuals with the poorest habits, modest changes (e.g., five more minutes of sleep, two minutes of activity, half a serving of vegetables daily) could add approximately one year of life.
* Optimal health behaviours (7–8 hours sleep, 40+ minutes of moderate-to-vigorous activity, healthy diet) were associated with nearly 10 additional years of life compared with the worst behaviour profiles.
