Depression is common among children and teenagers, yet many young people never get treatment. A study published in JAMA Pediatrics suggests that something as accessible as structured physical activity may help ease depressive symptoms in kids and teens.
Why researchers looked at exercise
Depression is the second most common mental health condition among children and adolescents, the study authors noted, but only a small share receive treatment specific to the condition. Barriers include cost, stigma, long waits for care and a shortage of child mental health specialists. The researchers wanted to know whether physical activity programs could work as an alternative or an add-on to standard treatment.
How the study was done
The team performed a meta-analysis, combining the results of 21 earlier studies involving more than 2,400 children and teens. Each study tested a physical activity program and measured changes in depressive symptoms.
What the researchers found
- Physical activity was linked to fewer depressive symptoms across the studies.
- About an hour, three times a week, appeared to give the biggest benefit, according to coverage by HealthDay. Study author Walter Thompson noted that this is close to general recommendations for weekly exercise.
- Teens over 13 benefited more, especially those already diagnosed with depression or another mental illness.
- Shorter programs, lasting less than 12 weeks, were associated with greater benefits. The researchers suggested that finishing a program may give kids a sense of accomplishment.
- Supervised, organized activities seemed to work best.
Thompson pointed out that structured physical education often drops off around age 12. Older kids may then lose the regular, organized activity that younger children get, which could be one reason depressive symptoms rise in the teen years.
How exercise helps mood
Experts don’t fully understand how exercise eases depression, but several things likely play a role. Physical activity can affect brain chemicals involved in mood, improve sleep, reduce stress and build confidence. Team sports and group activities also offer social connection, which is protective for mental health. Organizations such as Harvard Health and the UK’s National Health Service both describe exercise as a useful part of managing depression.
Important limits
A meta-analysis is only as strong as the studies it includes, and those studies varied in design and quality. Exercise is not a replacement for professional care when a child has moderate or severe depression. It’s best seen as one helpful piece of a broader plan.
What this means for you
If you’re a parent or caregiver, here are some ways to help a child or teen move more:
- Find something they enjoy. Dance, swimming, martial arts, biking or team sports all count. Enjoyment makes it easier to stick with.
- Look for structured options. After-school programs, clubs and community leagues provide regular, supervised activity.
- Start small. A daily walk together can be a good first step and an easy way to talk.
- Set an example. Kids are more likely to be active when the adults around them are.
- Know the warning signs. Ongoing sadness, irritability, withdrawal, changes in sleep or appetite, or falling grades lasting more than two weeks are reasons to talk with a pediatrician or mental health professional.
If a child talks about self-harm or suicide, seek help right away. In the U.S., you can call or text 988 to reach the Suicide & Crisis Lifeline.
The bottom line
Regular, structured physical activity was linked to fewer depressive symptoms in children and teens, especially older teens. It’s an accessible, low-cost tool that can support, but not replace, professional mental health care.
