Break Up Sitting Time to Cut Cancer Risk, Large UK Study Finds
A UK Biobank analysis of about 91,000 adults over roughly 12 years found that long, uninterrupted sitting is linked to higher cancer risk and mortality, while breaking up sitting with light activity lowers risk; replacing one hour of prolonged sitting with light movement is associated with about a 12% reduction in cancer mortality and a 6% reduction in cancer incidence, though the study shows associations rather than causation.
