Six Hours of Daily Screen Time Correlates With Measurable Cardiovascular Risk in Young Adults
A new study finds that young adults spending six or more hours on recreational screens outside school or work show significantly worse blood pressure, cholesterol, and BMI compared to those with more limited screen time — adding to evidence linking sedentary digital behavior to early cardiovascular disease risk.
Key Takeaways
- Young adults with 6+ hours of daily recreational screen time show measurably worse blood pressure, cholesterol, and BMI
- The primary mechanism is sedentary behavior — extended sitting impairs the metabolic signaling that muscle activity provides
- Cardiovascular risk behaviors established in young adulthood set trajectories that play out over decades
- The study cannot establish causality definitively; longitudinal research with behavioral interventions is needed
- Current guidelines already recommend interrupting prolonged sitting; this study extends that urgency to younger adults
