Does Your Grip Strength Actually Predict How Long You'll Live?
Published July 7, 2026
Here is a longevity biomarker that costs almost nothing to measure and beats most of the fancy panels I get asked about: how hard you can squeeze a dynamometer. In a prospective study of nearly 140,000 adults across 17 countries, grip strength was a stronger predictor of all-cause and cardiovascular mortality than systolic blood pressure (see [1]). Every 5 kg decline in grip strength was associated with a 16% higher risk of death from any cause. That is observational data, so we are looking at association, not proof of causation — but the effect size held after adjusting for age, education, physical activity, and a long list of confounders, which is more than I can say for most of the supplements in your medicine cabinet.
