Tiny Daily Tweaks to Sleep, Activity, and Diet Linked to Longer Life in New Studies

Wearable-data analyses plus modelling suggest minute behavior shifts correlate with longevity, not guaranteed effects.

The award-winning Mediterranean diet focuses on fresh fruits and vegetables, fish, olive oil, and little to no red or processed meat.

Overview

  • A Lancet analysis of about 135,000 adults using accelerometers estimated that adding five minutes of moderate-to-vigorous activity per day could reduce deaths by roughly 10% in the general population and about 6% among the least active.
  • The same study linked ten extra minutes of such activity with an approximately 15% lower mortality risk and suggested that cutting sedentary time by 30 minutes daily could lower deaths for many adults.
  • An eClinicalMedicine modelling study using UK Biobank data projected that, for people with the poorest habits, roughly five more minutes of sleep, two more minutes of moderate-to-vigorous activity, and half a portion of vegetables per day could add about one year of life.
  • The modelling associated the most favorable sleep, activity, and diet patterns with more than nine additional years of life and good health, and indicated combined small changes outperform single-behavior shifts, such as needing about 25 extra minutes of sleep alone to gain one year.
  • A SLEEP Advances analysis of U.S. county data reported that routinely sleeping under seven hours correlates with shorter life expectancy, with sleep a stronger correlate than diet, activity, or social isolation, and researchers emphasized these are associations rather than proof of causation.
