Sitting Too Long? Your Heart May Be at Risk

Spending most of the workday sitting is associated with higher cardiovascular risk. A large 2024 cohort study (481,688 adults) found that people who mostly sat at work had a 34% higher risk of cardiovascular death compared with those who mostly didn’t sit. Alternating between sitting and non-sitting at work wasn’t linked to higher risk, and adding ~15–30 minutes of daily physical activity may help offset the excess risk in predominantly seated workers.
Sitting Too Long? Your Heart May Be at Risk
Heart and circulatory system
Heart and circulatory system

Prolonged sitting puts a strain on the heart. It has been proven to increase the risk of cardiovascular disease.

Brain and concentration

Reduced blood flow impairs concentration and cognitive performance.

Neck pain

A forward-tilted head posture puts strain on the muscles of the cervical spine.

Tense shoulders

Rounded shoulders lead to chronic tension and discomfort.

Lower back

Compression of the lumbar spine can lead to disc problems.

hip flexor

Prolonged sitting causes the hip flexors to shorten and lose mobility.

Knee and ankle

Poor blood circulation impairs joint health in the long term.

What We Measured

What We Measured
When you sit, pressure builds up around the pelvis and thighs. High peak pressure can contribute to:
Pain in the buttocks, hips and lower back
Circulatory disorders
Fatigue from constantly changing seating position
Numbness and tingling
By reducing peak pressure, sitting feels more comfortable—and the strain on your body can noticeably decrease.

Sihoo Floating Support Technology — Noticeably Less Strain on Your Body
