World Heart Day 2025: Protecting Children’s Hearts

There was a time when you might have heard that heart-related issues were limited to older people. Fast forward to today, things are changing rapidly, but not in an appropriate manner. You often come across news or social media posts about young adults, and sadly, even children, suffering from unexpected heart issues.

One recent heartbreaking example is from Chamarajanagar, where an 8-year-old schoolgirl collapsed due to a sudden cardiac arrest immediately in her classroom. Incidents like this remind you all that heart issues are not just an “adult problem” anymore. Though rare in kids, with about 1 to 3 cases per 1,00,000 children, it’s still greatly concerning.

So, why is this happening? The answer is not that straightforward, and reasons can be complex, ranging from lifestyle factors to hidden medical conditions. What’s crucial is to spread heart health awareness for children and take steps to protect little hearts. In this blog, you’ll learn why heart issues in children are rising and what you can do to keep your child’s heart healthy and strong.

Why Are Heart Issues in Children Rising More Than Ever?

To understand this, you need to be aware of the basics first: for your or your child’s heart to stay healthy, daily movement is crucial; children need to eat clean and nutritious food; the body’s blood vessels need to be in good shape; stress should be the healthy kind that boosts learning and creative thinking; and of course, there should be no hidden heart-related conditions.

When any of these factors are off balance, it can contribute to heart issues in children and pointing to one single factor is nearly impossible.

Here are the top 5 reasons behind the rising heart problems in kids:

1. Adulterated Food

Even if your child wants to eat healthy, fruits, vegetables, and even packaged items nowadays contain harmful chemicals, pesticides, or additives that slowly strain a child’s heart. As time passes, these lower the food’s natural nourishment and worsen long-term health risks.

What’s in your hand: Wash the fruits and vegetables properly, and if possible, try to choose fresh, unprocessed food.

2. Less to No Physical Activity

As you are also frustrated about the fact that children today spend more time indoors, glued to their screens instead of running or playing outside. This weakens their heart and reduces stamina. A sedentary lifestyle is like inviting early heart issues in the future.

What’s in your hand: Push your child to play outside, walk, cycle, or join sports for a minimum of 1 hour daily.

3. Pollution Affecting Kids' Health

The worsening of the air quality index and water pollution does not just harm the lungs; it also slowly damages blood vessels (which carry oxygen and blood) and even influences genes that control heart health. Growing up in a polluted environment increases hidden risks.

What’s in your hand: Set up indoor plants and air purifiers, and prefer greener open areas for your child’s play.

4. Increase Stress in Childhood

Stress was not even a word in your childhood, but let's admit that today's kids are dealing with stress very early in their lives. The pressure of studies, competitive activities, the pressure of good looks due to social media, and more nuclear families can cause chronic stress in children. Over time, stress hormones harm blood circulation and heart rhythm.

What’s in your hand: Give your child emotional support, balanced schedules, and time to relax with activities they enjoy.

5. Genetic Diseases

Some children have inherited heart-related issues from family history, making them more vulnerable from birth. Although this can’t be prevented, it can be tracked and managed with timely care.

What’s in your hand: If heart issues run in your family, then get your child’s heart checked regularly and follow the doctor’s preventive advice.

Note these reasons are for educational purposes; for any heart-related issues in your child, consult your healthcare professional.
