We know exercise is great for kids’ growing bodies, but how much do we know about all the other benefits? “When I think about exercise, I actually go to the mental health benefits, first,” says Dr. Shelly Flais, mother of four, national AAP spokesperson, assistant professor of pediatrics at Northwestern University School of Medicine and author of several parenting books including “Raising Twins.” That’s right, active playtime is great for kids’ brains, and so much more.

In March 2020 the American Academy of Pediatrics released a report with specific recommendations for exercise:

For infants: physical movement several times a day through interactive floor-based play.
For kids age 3 to 5: three hours or more of physical activity every day.
For kids 6 to 17 years old: 60 minutes of physical activity daily.

Something that’s important enough to do every day must be doing a lot for our kids. Well, you’d be amazed at all the different ways physical activity benefits children and teens. Here are several you don’t want to miss.

How exercise helps children’s physical development

Improves cardiovascular health

We’ve long known that exercise makes your heart and lungs stronger, and that definitely goes for children. Starting at a young age, vigorous activity can help reduce their risk for cardiovascular disease later on in life.

Helps develop beneficial body composition

Physical activity helps build more of the kind of lean muscle mass that supports joints and improves kids’ metabolism. This puts them at lower risk for diabetes. And while body fat in general isn’t necessarily harmful for young people, abdominal fat specifically has been linked with cardiovascular disease and other health issues; combined with healthy food choices, getting a variety of exercise can help reduce that harmful abdominal fat.

Increases bone health

Bone-loading exercises like jumping, dancing, running and tennis can help make kids’ bones denser, which makes them stronger. This is especially important for females, who tend to lose more bone mass than males later on in life.

Improves balance

The more kids move, and in a variety of ways, the better they get at preventing falls and injury. Young people who begin their adulthood with stronger limbs tend to have better balance even into middle age.

Prevents future pain

The postures associated with looking at screens all day can cause our bodies harm over time. This is something Tarik Kitson, co-founder and executive director of youth fitness program Active Plus, is trying to correct. “We want to be able to get to kids’ bodies at a younger age to correct those habits,” he says. His program includes movements like pulling exercises that can help correct posture “so they won’t hurt when they get older.” As a lot of us know all too well, it’s harder to address that pain in your 30s and 40s.

Boosts childrens’ immune systems

Wouldn’t we all love to reduce the number of colds and sore throats our kids come home with. Moderate to high levels of physical activity are linked to lower incidents of illness and infection in children. Exercise is a natural immune system booster.

Helps children develop physical literacy

What is that? It’s “the ability, confidence and desire to be physically active for life,” as the Aspen Institute puts it. Physical literacy sets kids up for a lifetime of enjoying great exercise habits — it even makes teens less likely to smoke. It’s an excellent foundation that will serve them for years to come.

How exercise helps children’s cognitive development

It’s literally good for the brain

Exercise improves children and teens’ memory and processing speed (as it does for adults). For people of all ages, exercise helps your brain change and adapt in response to experiences (also known as brain plasticity). It helps kids improve their executive functioning (your ability to plan, control your behavior and use your memory), and that’s especially true for kids who have difficulty with that.

Helps kids get the most out of school

Physical activity, especially during the school day, helps children pay better attention and put more effort into their schoolwork. That’s right, recess helps your kids learn better. Kids who move more tend to get better grades in school.

Intense physical exercise is especially helpful for children and teens with ADHD symptoms. “I always tell my families in the office to think of exercise as another tool or another medication, if you will, that helps us keep focused,” says Flais.

Helps kids sleep better

Why is this important? Because sleep is critical to brain development and functioning. Exercise helps kids fall asleep faster, and we all want that! It’s unclear if it help kids sleep longer (the research is mixed), but it does seem to improve that sleep quality.

And it’s even more beneficial if that exercise happens outdoors — yes, even in the dead of winter. Flais tells her teenage patients, “You gotta have some outdoor movement every day just to kind of keep your circadian rhythm, or your internal clock, appropriate.” Outdoor exercise helps us reset the brain, she says.

How exercise helps children’s psychological well-being

Reduces depression, anxiety and substance use

Doctors aren’t sure that regular exercise can prevent depressive episodes, but it does seem to help children and teens with depression have less severe symptoms. It also helps reduce a number of other negative emotional states, like anxiety. Physical activity helps children deal with stress better, while sedentary kids are at higher risk for alcohol and drug use.

Resets moods

Flais recalls how, when her youngest was a toddler, she could reset a cranky mood with a walk outside, “even if it was just to examine bugs up on the driveway.” It was the movement with a change in environment that changed the rhythm of the day and set a new tone. This goes for teenagers as well. If you’re having a bad day, she says, movement can change that, even if it’s a five-minute dance party. “The silly stuff is the best stuff,” she says. “A good belly laugh counts as exercise.

Builds confidence

Under certain conditions, kids who don’t identify as athletic can build confidence when they learn new physical skills. Kitson has been running much of Active Plus virtually since the coronavirus pandemic. What he’s found is that kids who used to feel self-conscious or embarrassed to exercise in front of their peers now enjoy exercising in the privacy of their own homes. “So that’s confidence boosting for them to be able to work out and be able to do these things,” Kitson says.
