Nature is the Antidote

President & CEO, Children & Nature Network

When I was a kid, playing outdoors was a regular part of my daily life. I spent countless hours in the creek behind my house, in the garden with my grandma, and exploring with friends — without constant adult direction. As kids, we didn’t think about being outside, we just were. As a society, we didn’t understand how important this unstructured outdoor time was, until it vanished. 

Today, we are witnessing the first generation of children to grow up in a fully online world. Childhood has moved indoors. Unstructured time outside is rare. And the consequences are real. 

The result is a children’s health crisis. 

A 2024 study published in JAMA found that a U.S. child was 15 to 20 percent more likely to have a chronic condition in 2023 than in 2011, with depression, anxiety, and obesity among the fastest-growing diagnoses. Nearly one in five teens has experienced a major depressive episode in the past year. Diagnosed anxiety among adolescents has increased 61 percent since 2016.  

These numbers are not abstract. They represent children in our classrooms, on our playgrounds, and in our communities. And the crisis is not hitting all children equally — kids living in poverty and communities of color carry a disproportionate share of this burden, often in the same neighborhoods where access to safe outdoor spaces has been historically denied. 

Children & Nature Network co-founder Richard Louv called this nature-deficit disorder which is not a clinical diagnosis, but a powerful way of naming the psychological, physical, and cognitive toll of growing up disconnected from the natural world. In 2023, the U.S. Surgeon General reinforced the urgency, warning that social media poses a profound risk to adolescent mental health. When children lose access to physical, community-rooted places to play and grow, they don’t simply stay inside. They go online — into environments not built with their wellbeing in mind. 

Nature is a proven antidote. 

For nearly 20 years, Children & Nature Network has led a national and global effort to reconnect children with the outdoors. The evidence is clear: 

  • Mental health: Children who spend just 60 minutes daily in nature have a 50 percent lower risk of mental health issues with the greatest benefits for children from lower-income households.
  • Physical health: Physical activity is two to three times higher when children are outside compared to indoors making outdoor spaces one of the most accessible public health tools we have. 
  • Learning: Green schoolyards and nature-rich environments are linked to better focus, reduced ADHD symptoms, improved test scores, and stronger school attendance. 
  • Stewardship: Research shows that children who spend more time outdoors at age 6 report significantly more pro-environmental behaviors at age 18. The investment in children’s connection to nature pays forward across generations. 

The communities we work with see, on average, a 15:1 return on investment — through additional funds leveraged and measurable improvements in children’s health, well-being, and learning. Equitable access to nature also strengthens community health, social cohesion, and climate resilience. 

But ultimately, believing is seeing. Spend a few minutes watching child-led play in a natural setting and you’ll witness something that no data point can fully capture: wonder, joy, and the quiet confidence of a child who knows they belong in the world around them. That’s something every child deserves and it reminds us that we are all connected to a much bigger story.
