New Study Reveals Hidden Health Risks of Excessive Screen Time in Children

Excessive Screen Time in Children Linked to Serious Health Risks, New Study Finds

A new international study has sounded the alarm on the growing health risks associated with excessive screen time among children and adolescents. Researchers have found that each additional hour spent on screens—whether phones, tablets, or TVs—significantly increases the risk of developing cardiometabolic conditions such as heart disease, high blood pressure, and Type 2 diabetes.

The Research Behind the Warning

Conducted by the University of Copenhagen and published in the Journal of the American Heart Association, the study analyzed screen time and sleep patterns in over 1,000 children aged 10 to 18. The findings are striking: even one extra hour of daily screen exposure can raise a child’s risk of developing serious metabolic issues.

Lead researcher David Horner explained that children with three additional hours of screen time per day showed a measurable increase in cardiometabolic risk compared to their peers. These risks include elevated cholesterol, insulin resistance, and high blood pressure—conditions that often persist into adulthood.

Sleep Disruption Adds to the Danger

The study also highlighted the impact of screen time on sleep quality. Children who spent more time on screens tended to sleep less and had poorer sleep patterns, which further compounded their health risks. Poor sleep combined with sedentary behavior creates a dangerous cycle that can accelerate the onset of lifestyle-related illnesses.

Global and Local Implications

While the study focused on children in Denmark, its implications are global. In countries like Pakistan, where urban children increasingly rely on digital devices for entertainment and education, the findings are especially relevant. Experts warn that without early intervention, the nation could face a surge in youth-related health issues.

What Parents and Guardians Can Do

Health professionals recommend the following steps to mitigate risks:

• Limit non-educational screen time to two hours per day
• Encourage physical activities such as walking, cycling, or sports
• Establish tech-free zones at home, especially during meals and bedtime
• Monitor sleep patterns and promote consistent sleep routines

A Call to Action for Public Health

The study’s findings are expected to influence public health policies and educational strategies worldwide. In Pakistan, digital literacy programs and awareness campaigns could play a vital role in reshaping screen habits and promoting healthier lifestyles among children.
