Devi Sridhar Rejects 5-Minute Exercise Claim, Citing WHO's 150-300 Minutes a Week

Summary

  • Sridhar argues recent headlines overstated a Lancet analysis, saying five minutes of daily exercise is not enough to stay healthy or remain fully fit into old age.
  • The study pooled roughly 40,000 people from seven US and Nordic cohorts plus 95,000 UK Biobank participants, then modeled how five extra minutes of moderate activity might cut deaths by 6%-10% rather than testing a five-minute routine.
  • She says the findings support 'something is better than nothing'—especially for the least active—but should not replace a broader exercise plan.
  • WHO guidance still points adults to 150-300 minutes of moderate activity a week, and Sridhar says health also depends on balancing cardio, strength and flexibility rather than chasing a minimal time target.
