Brief bursts of intense exercise may slash disease risk, study finds

A study of more than 96,000 people found that just a few minutes of vigorous daily activity—such as sprinting for the bus, fast stair climbs, or active play—was linked to lower risks of eight major diseases and reduced all-cause mortality. Even 15–20 minutes per week of intense effort yielded meaningful health benefits, though safety and personalization are important, especially for older adults.
