Tiny daily tweaks across sleep, activity, and diet can add years to life, study says
Australian researchers using UK Biobank data find that small, combined changes in sleep (as little as 5 extra minutes per night), moderate daily activity (about 2 more minutes), and a half-serving increase in vegetables can add roughly one year to lifespan. More substantial, synergistic changes—7.2–8 hours of sleep, about 43 minutes of moderate activity, and a higher-quality diet—are associated with more than nine additional years of healthspan and lifespan. The findings emphasize that modest changes across multiple behaviors have greater impact than changing one area alone, offering a practical, flexible path for patients and clinicians.
