A healthy heart is one of the greatest gifts we can give our children. While heart disease is often thought of as an adult health problem, the habits that protect the heart begin much earlier—during childhood. By age six, children are developing routines and preferences that can influence their health for years to come. The foods they eat, the amount they move each day, and even how well they sleep all play a role in building a strong, healthy heart.

The good news is that promoting heart health does not require expensive sports equipment or hours at the gym. Running through the backyard, riding a bike, dancing in the living room, or playing tag with friends are all excellent ways to strengthen a child’s heart while having fun.

Research shows that children who establish healthy habits early are more likely to remain physically active and maintain healthier lifestyles into adulthood, reducing their risk of heart disease, type 2 diabetes, obesity, and high blood pressure later in life (American Heart Association [AHA], 2024; Centers for Disease Control and Prevention [CDC], 2024).

Why Heart Health Begins in Childhood

The heart is a powerful muscle that works every second of every day. It pumps oxygen-rich blood throughout the body, delivering the nutrients that muscles, organs, and especially the brain need to function properly.

Although heart disease usually develops later in adulthood, research has shown that some of the early changes that contribute to heart disease can begin during childhood if healthy habits are not established (National Heart, Lung, and Blood Institute [NHLBI], 2023).

Children who stay physically active tend to have:

Stronger hearts
Healthier blood pressure
Better cholesterol levels
Stronger muscles and bones
Healthier body weight
Improved endurance
Better overall physical fitness

Building these healthy habits now lays the foundation for a lifetime of better health.

How the Heart Works: A Kid-Friendly Explanation

One fun way to teach children about their bodies is to explain the heart in simple terms.

You might tell your child:

“Your heart is like a super-strong pump. Every time it beats, it sends blood all around your body. That blood carries oxygen and nutrients that help your muscles run, your brain think, and your body grow. When you run, jump, dance, or play, your heart works a little harder and gets even stronger—just like your muscles do.”

Helping children understand why exercise matters often increases their motivation to stay active.

How Much Exercise Does a 6-Year-Old Need?

According to the CDC and the U.S. Department of Health and Human Services, children ages 6 to 17 should get at least 60 minutes of moderate to vigorous physical activity every day (CDC, 2024).

That may sound like a lot, but it doesn’t have to happen all at once. Physical activity can be spread throughout the day.

For example:

Walking to school
Recess
Playing outside after school
Riding a bicycle
Family walks
Dancing in the living room
Playing soccer
Swimming
Playing tag

Every minute of movement counts.

Children also benefit from activities that strengthen muscles and bones several days each week, such as climbing playground equipment, jumping rope, gymnastics, or playing on monkey bars.

Exercise Helps the Brain, Too

When children exercise, it isn’t just their hearts that benefit—their brains do as well.

Physical activity increases blood flow to the brain, delivering oxygen and nutrients that help brain cells work more efficiently. Exercise also stimulates the release of chemicals called brain-derived neurotrophic factor (BDNF), often described as “fertilizer for the brain,” because it helps brain cells grow and form new connections (Ratey & Hagerman, 2013).

Studies have found that physically active children often demonstrate:

Better attention
Improved memory
Stronger problem-solving skills
Increased classroom participation
Better emotional regulation
Reduced anxiety
Higher academic achievement (Donnelly et al., 2016)

Even just 20 minutes of active play before school or homework can improve concentration and readiness to learn.

Physical Activity Supports Emotional Health

Children often express emotions through movement. Running, jumping, climbing, and playing help release energy while reducing stress and anxiety.

Exercise also increases the production of natural chemicals called endorphins, which improve mood and help children feel happier and calmer.

Regular physical activity has been associated with:

Lower stress levels
Reduced symptoms of anxiety
Improved self-esteem
Better confidence
More positive social interactions

At six years old, many children are still learning how to manage frustration and disappointment. Active play provides a healthy outlet for these emotions while teaching resilience and perseverance.

Healthy Habits Become Lifelong Habits

Children learn by watching the adults around them.

If parents regularly take walks, play outside, ride bikes, or stay active together, children begin to see physical activity as a normal part of everyday life—not as a chore.

Rather than saying:

“We have to exercise.”

Try saying:

“Let’s go on an adventure together!”

Making movement fun helps children build positive memories around physical activity that can last well into adulthood.

Research suggests that children who participate in active family routines are more likely to remain active as teenagers and adults (American Academy of Pediatrics [AAP], 2023).

Fun Ways Families Can Stay Active Together

Exercise doesn’t have to involve organized sports. Some of the healthiest activities are also the simplest.

Try these family-friendly ideas:

Take a nature walk and look for birds or insects.
Ride bikes around the neighborhood.
Visit a local playground.
Create an obstacle course in the backyard.
Dance together during your favorite songs.
Kick a soccer ball at the park.
Toss a Frisbee.
Go swimming together.
Play tag or hide-and-seek outside.
Walk the family dog.

The goal isn’t perfection—it’s making movement a regular and enjoyable part of everyday family life.

What Does “Heart-Healthy” Play Look Like?

Parents often wonder whether their child is active enough.

Heart-healthy play usually includes activities that make children:

Breathe a little faster
Laugh and smile
Break a light sweat
Feel their heart beating faster
Want to keep playing

Children naturally alternate between short bursts of energy and brief periods of rest. This pattern is completely normal and is actually one of the healthiest ways young children exercise.

Screen Time and Heart Health

Technology is a part of everyday life, but too much screen time can reduce the amount of time children spend moving their bodies. Research has found that children who spend more time sitting are at greater risk for obesity, poor cardiovascular fitness, and other long-term health concerns (American Academy of Pediatrics [AAP], 2023).

Screens are not the enemy—they simply need to be balanced with active play.

Here are a few ways to encourage more movement at home:

Take a 5–10 minute movement break after every 30–60 minutes of screen time.
Choose active games that involve dancing or movement.
Keep televisions and tablets out of bedrooms when possible.
Plan one family activity outdoors each day.
Be a role model by putting away your own phone and joining the fun.

Children are much more likely to stay active when they see the adults in their lives enjoying movement too.

Signs Your Child May Need More Physical Activity

Every child has different interests and energy levels, but some signs may suggest they would benefit from more daily movement.

Your child may need more physical activity if they:

Tire easily during play.
Spend most of their free time sitting.
Prefer screens over active play every day.
Have difficulty sleeping at night.
Seem restless or have trouble focusing.
Avoid running, climbing, or playground activities because they become tired quickly.
Rarely participate in outdoor play.

If you have concerns about your child’s physical activity level or overall health, speak with your pediatrician during their next well-child visit.

A Week of Heart-Healthy Family Activities

You don’t need an expensive gym membership to build a healthy heart. Small amounts of movement throughout the week can make a big difference.

Monday

Take a 20-minute family walk after dinner and let your child choose the route.

Tuesday

Create an indoor dance party with your child’s favorite songs for 20–30 minutes.

Wednesday

Visit a local playground and encourage climbing, swinging, and running.

Thursday

Ride bikes or scooters together around the neighborhood or at a local park.

Friday

Play backyard games such as tag, kickball, or relay races.

Saturday

Go on a family nature walk or easy hiking trail. Look for birds, insects, flowers, or interesting leaves to make the walk an adventure.

Sunday

Create a backyard obstacle course using cones, pool noodles, jump ropes, pillows, or chalk and let your child race through it several times.

Remember, these activities don’t have to total exactly 60 minutes at once. Several shorter periods of active play throughout the day add up.

Five Heart-Healthy Games for 6-Year-Olds

Making exercise feel like play is one of the best ways to build lifelong fitness habits.

Animal Races

Hop like a frog, crawl like a bear, waddle like a penguin, or gallop like a horse.

Color Hunt Walk

Take a walk and challenge your child to find something of every color of the rainbow.

Balloon Volleyball

Use a balloon instead of a ball to improve coordination while keeping children moving indoors.

Freeze Dance

Dance while music plays, then freeze like a statue whenever the music stops.

Fitness Dice

Write activities on a large foam die or pieces of paper:

10 jumping jacks
Run in place
Hop on one foot
Bear crawl
Stretch
Dance

Roll and complete each challenge together.

Heart-Healthy Habits Beyond Exercise

Physical activity is just one piece of heart health. Other daily habits also help protect a child’s heart.

Encourage your child to:

Eat a variety of fruits and vegetables every day.
Choose whole grains when possible.
Drink plenty of water throughout the day.
Get 9–12 hours of sleep each night, as recommended for school-age children.
Brush and floss their teeth daily, since good oral health has been linked to better overall health.
Spend time outdoors and limit prolonged sitting.

Healthy habits work best when they become part of everyday family life rather than feeling like special rules.

Safety Tips for Active Play

Keeping children safe allows them to enjoy movement with confidence.

Before active play:

Make sure children wear properly fitted sneakers.
Wear a helmet when riding a bicycle, scooter, or skateboard.
Encourage water breaks, especially on hot days.
Apply sunscreen when spending extended time outdoors.
Dress appropriately for the weather.
Supervise playground activities and teach children to use equipment safely.
Encourage children to listen to their bodies and rest if they feel dizzy, unusually tired, or overheated.

A little preparation helps children stay safe while they build healthy, active habits.

Growing Together Tip

Children don’t remember every lesson we teach—but they do remember the experiences we share.

A family walk after dinner, a game of tag in the backyard, or dancing together in the kitchen may seem like simple moments, but they create positive memories around physical activity. Those memories can shape lifelong attitudes toward health and fitness.

The goal isn’t to raise the fastest athlete—it’s to raise a child who enjoys moving, feels confident in their body, and understands that taking care of their heart is an important part of taking care of themselves.

What the Research Says

Research consistently shows that regular physical activity during childhood supports nearly every aspect of a child’s health.

Children who are physically active are more likely to have:

Stronger hearts and healthier blood pressure.
Better concentration and academic performance.
Improved memory and executive functioning.
Lower levels of anxiety and stress.
Better sleep quality.
Stronger bones and muscles.
Healthier body weight.
Greater self-confidence and emotional well-being (CDC, 2024; Donnelly et al., 2016; American Heart Association, 2024).

The American Heart Association also reports that children who establish healthy eating and exercise habits early are significantly more likely to maintain those habits into adulthood, lowering their lifetime risk of heart disease, stroke, type 2 diabetes, and other chronic illnesses (AHA, 2024).

Every bike ride, game of tag, family hike, and dance party is an investment in your child’s future health.
