Study: More Screen Time Linked to Heart Risks in Children
A new study suggests that too much screen time can be bad for kids' hearts.
Researchers found that more time spent watching screens, playing games, or using phones is linked to a higher risk of heart problems like high blood pressure and unhealthy cholesterol levels.
The study also showed that getting enough sleep is important, as kids who sleep less are at greater risk.
To help kids stay healthy, it's recommended to limit screen time, especially before bed.
Encourage outdoor play, and set a good example by reducing your own screen use.
Remember, eating healthy, being active, and getting good sleep are key to keeping hearts strong.
Study links increased screen time to heightened heart risks in children and adolescents.
Each extra hour of screen time is associated with a rise in cardiometabolic risk.
Sleep duration plays a crucial role, with shorter sleep amplifying the risks.
The study found a distinct set of blood-based biomarkers connecting screen habits to metabolic changes.
Experts recommend strategies to reduce screen time and promote heart health.
