A new study has found that spending more than six hours a day on screens may significantly increase the risk of heart-related health issues in young adults, regardless of physical activity levels.
Researchers observed that prolonged screen exposure was associated with higher blood pressure, increased cholesterol levels, and a rise in body mass index (BMI). The findings suggest that screen time itself acts as an independent risk factor, rather than simply reflecting a lack of exercise.
The study, conducted on adults in Pakistan, also revealed that individuals who combined high screen time with low physical activity faced even greater health risks. This combination showed a stronger impact on blood pressure and body weight compared to either factor alone.
On the other hand, participants who engaged in regular physical activity demonstrated healthier outcomes, including lower waist circumference and improved lipid levels.
Experts believe the negative effects of excessive screen use may be linked to sedentary behavior, disrupted sleep patterns, stress, and unhealthy habits such as increased calorie intake during screen use.
The findings highlight growing concerns about the role of digital lifestyles in shaping long-term health. Researchers emphasize the need for greater awareness and lifestyle changes, including reducing screen time and increasing physical activity, to lower the risk of cardiovascular disease.
Further studies are expected to explore whether reducing screen exposure can directly improve health outcomes.
