Sitting for over 30 minutes at a stretch may raise cancer death risk: Study

Study of over 91,000 UK Biobank participants found prolonged sitting for more than 30 minutes increases cancer mortality risk by 10%.

Each additional hour of continuous inactivity raises the risk further, but brief movement breaks like short walks may offset it.

Lead author Dr Frederick Ho of University of Glasgow states breaking up sitting time with light activity is protective.

Research published in PLOS Medicine shows replacing extended inactivity with light movement, including slow walking or chores, reduces cancer death risk.

Current guidelines focus on moderate/vigorous exercise, but findings show light movement should not be ignored.
