The Claim
A 7.5-hour simulated workday of prolonged sitting significantly increases seated systolic, diastolic, and mean arterial blood pressure in adults with overweight/obesity and elevated blood pressure, with effect sizes ranging from 0.25 to 0.44.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
During a 7.5-hour period of continuous sitting, adults with overweight or obesity and elevated blood pressure experience measurable increases in systolic, diastolic, and mean arterial blood pressure.
See the scientific wording
A 7.5-hour simulated workday of prolonged sitting significantly increases seated systolic, diastolic, and mean arterial blood pressure in adults with overweight/obesity and elevated blood pressure, with effect sizes ranging from 0.25 to 0.44, suggesting acute cardiovascular strain during sedentary work.
When a person sits still for a long time, blood collects in the legs because the muscles aren't moving to push it back up. This reduces the amount of blood returning to the heart, so the heart pumps less. The body responds by tightening blood vessels throughout the body and increasing heart rate, which raises blood pressure.
What the research says
1 studyThis study found that when people who are overweight and have high blood pressure sit at a desk for 7.5 hours without moving, their blood pressure goes up — just like the claim says. It’s like their heart has to work harder just from sitting too long.
