Increased Screen Time Linked to Higher Heart Disease Risk in Youth

Sun 10th Aug, 2025

Recent research from Denmark indicates that excessive screen time significantly elevates the risk of developing heart and metabolic diseases among children and young adults. The study, which examined the screen usage and sleep patterns of over 1,000 individuals aged 10 to 18, highlights a concerning correlation between prolonged screen exposure and various cardiometabolic risk factors.

The findings, published in the Journal of the American Heart Association, reveal that young individuals who spend extended hours on devices such as smartphones and televisions may face a heightened likelihood of conditions like high blood pressure, elevated cholesterol levels, and insulin resistance. These factors are precursors to more severe health issues, including cardiovascular diseases and diabetes.

According to the analysis, each additional hour of screen time per day increases the risk of these diseases. For instance, a child who engages in three extra hours of screen use daily could experience a risk increase equivalent to approximately 25% to 50% higher than their peers. This statistic underscores the potential public health implications, as such a trend could result in a notable shift in cardiometabolic risk across populations, extending into adulthood.

While opinions among researchers vary regarding the impact of screens on different age groups, there is a consensus that children and adolescents are particularly vulnerable compared to adults. The study serves as a crucial reminder of the importance of monitoring screen time to promote healthier lifestyles among the younger population.

As technology continues to permeate daily life, understanding its effects on health, particularly in formative years, becomes increasingly vital. Parents and caregivers are encouraged to implement strategies that limit screen exposure, thereby fostering better health outcomes for future generations.
