In today’s digital age, children and teens are constantly in front of some screen or the other. Sometimes a phone, tablet, TV or gaming console. But now, a new research has issued a big warning for parents. A study conducted in Denmark supported by the American Heart Association (AHA) has shown that children’s excessive screen time is causing serious harm to their cardiovascular and metabolic health. According to research, the effect of this digital habit was clearly visible in children aged between 10 years to 18 years. The more time they spend on screens, the higher their risk factors like blood pressure, cholesterol and insulin resistance. Simply put, every extra hour spent on screens is taking a toll on kids’ heart health.
Studies have also shown that this risk is even higher in children who do not sleep. That is, if a child spends late nights on a mobile phone and gets little sleep, a “metabolic fingerprint” is being created in his body. A biological marker that can lead to diseases such as heart disease or diabetes.
Researchers said this is not just a behavioral problem, but has direct biological effects. They analyzed blood samples from children and found that those who had excessive screen time had higher levels of substances in their blood that indicate metabolic imbalance.
Experts believe these results are a warning to parents. Children are spending a large part of their day on the phone, TV or playing games, but this habit is gradually becoming a threat to their heart health. Therefore, parents should limit their children’s screen time and pay attention to their sleep. “We found a direct association between screen time and cardiometabolic risk,” said the study’s lead author. “It is important that children and adolescents lead a healthy lifestyle that includes balanced screen time, adequate sleep, and physical activity.
Experts say parents should now keep an eye on their children’s digital habits. Family activities, outdoor games and reading should be encouraged to keep children away from screens. Apart from this, the best solution is to turn off all screens at least an hour before bedtime, as this time relaxes both the heart and mind of children.
