Move More, Sit Less: Tiny Changes That Cut Big Health Risks
New research confirms that prolonged sitting raises mortality and disease risk, especially when sitting 11+ hours daily; a JAHA study of nearly 6,000 older women found 11+ hours a day linked to a 57% higher all-cause death risk and 78% higher heart-disease death risk over 10 years. The mechanisms involve muscle inactivity reducing glucose uptake and blood flow impairment. Practical fixes include not sitting all day, adding movement even if you exercise, breaking up desk time with short walks or stretches every 30 minutes, using adjustable standing desks, and habit-stacking movement into daily routines such as walking meetings or post-call strolls.
