Parenting Tips

In the modern digital world, children have become accustomed to daily screen usage. From virtual classes and educational material to cartoons, games, and social media, children are spending more time in front of screens than ever before. While technology has it’s upsides, excessive screen usage impacts a child’s heart, especially when screen time outweighs physical activity and other healthy routines.

According to Dr. Manvinder Singh Sachdev Senior Pediatric Cardiologist and Founder of NanheDil – The Child Heart Centre, heart health begins in childhood. The habits a child learns early in life, especially when it comes to physical activity, are important determinants of that children’s heart health later in life.

Understanding the Link Between Screen Time and Heart Health

When children sit in front of a screen their body enters a sedentary state which means their bodies become less active and their hearts do not get the stimulation they need.

When screen time is excessive children become sedentary . A sedentary lifestyle in children can lead to:

• Reduced cardiovascular fitness
• Poor stamina and endurance
• Increased risk of childhood obesity

Dr. Singh highlights that children’s lack of physical activity can heighten the risk of high blood pressure and diabetes, as well as heart disease in later years.

Effects of Screen Time on Weight and Metabolism

It is common for children to munch on snacks while watching screen. Such snacks tend to be the following:

• Deep-Fried Foods

• Highly Sugary Foods

• Other Packaged/Highly Processed Foods

This combination of mindless eating, coupled with a sedentary lifestyle, can lead to unhealthy weight gain and increased strain on the heart. This mindless weight gain struggle is accompanied by the following:

    • Increased Cholesterol

    • Insulin Resistance

    • Early Onset Heart Disease

Parents are routinely counselled on lifestyle changes (reducing screen time, in specific) to significantly improve a child’s heart health at NanheDil – The Child Heart Centre.

Screen Time, Sleep, and Heart Health

Late-night screen exposure affects the body’s natural sleep cycle. Blue light from screens suppresses melatonin, the hormone responsible for sleep. Poor sleep can lead to:

• Hormonal imbalance
• Increased appetite
• Higher stress levels
• Raised blood pressure

Dr. Sachdev explains that adequate sleep is essential for a child’s heart to rest, repair, and grow. Children who don’t sleep well are more likely to gain weight and develop heart-related risk factors.

How Much Screen Time Is Too Much?

While screen time isn’t totally avoidable, balance is important. Recommended values are: Limiting recreational screen time to 1-2 hours per day Not using screens at least 1 hour before sleeping Having screen-free meals and family time Dr. Manvinder Singh Sachdev stresses that screens should never take the place of the outdoors, sports, or any form of physical exercise.

Heart-Healthy Alternatives to Screen Time

Reducing screen time opens the door to activities that strengthen the heart naturally:

• Outdoor play like running, cycling, skipping
• Sports such as football, swimming, badminton
• Family activities like evening walks or yoga
• Creative play including dancing, drawing, or gardening

These activities improve blood circulation, strengthen the heart muscle, and help children maintain a healthy weight.

What Parents Can Do: Practical Tips

Parents greatly influence their child’s way of living.

• Be a Role Model

Opting for less screen time yourself makes it easier for children to limit their screen use.

• Create a Daily Routine

Make a schedule including schoolwork, screen time, physical activities, and sleep.

Children should be rewarded with time to play outside instead of extra screen time.

Dr. Sachdev mentions that early risk assessment and mitigative strategies will deal with the risk before it becomes a problem.

Conclusion: A Healthy Heart is Built Early

Screens are a constant in every child’s life and allow them to do fun and educational activities. However, they should be used in moderation to allow for unstructured, active, outside play. Healthy meal choices, enough sleep, and active play can improve and maintain the heart health of any child today and in the future.
