Helping young people own their attention and build the skills and mindsets they need to flourish as humans.

Our big kids need to go outside more than ever, and we can help!

It's easier than we may think to get kids the benefits of green time.

Though I did not grow up in an outdoorsy family, like many kids in the 80s and early 90s, my childhood memories are predominantly of exploring and playing outside. And later, as a teacher and a parent, I fell madly in love with the natural world. For years, nature has been at the heart of my work in founding and growing Tinkergarten. I see nature as inextricably linked with kids’ wellbeing, learning, and development. And, now, as we embark on a10d, I am reminded anew of how essential nature is in matters of attention.

And yet, as I parent three teens who were literally raised on outdoor play, it has become harder than I would’ve expected to build in outside time. Middle and high school offer woefully little time outdoors. Kids get so busy with sports, activities, and relationships. Schoolwork mounts, and digital connection, games and media vie for the slots of free time that fall in between.

But here’s what I know from both the science and my own experience: big kids’ brains, bodies and spirits get benefits from the outdoors that nothing else can replicate. And, perhaps the best part is that getting those benefits doesn’t require as much outdoor time as we might think.

What nature does to the brain and body

As an outdoor educator, I started paying close attention to attention when I noticed the almost magical impact that being in the natural world has on kids’ capacity to focus. Natural environments offer an incredible combination of stimulating and calming effects. The big container of the great outdoors also liberates the mind and spirit—quite the opposite impact that rigid, indoor environments have on us. That old saying, “You can’t bounce off the walls if there are no walls” is not just true for little kids. Once kids get used to being outdoors, it just seems both easier and more joyful for kids to engage in whatever they’re doing.

A 2023 summary of research reviews found consistent support that increased exposure to nature is associated with a wide range of positive outcomes for kids, including increased physical activity and improved cognitive functioning, behavioral health and mental wellbeing. Studies also show that time in nature reduces stress and boosts mood — something the so-called “anxious generation” needs more than ever. At this point, the data is so clear that it almost feels too obvious to mention.

For decades, studies have also largely supported Attention Restoration Theory. The theory proposes that spending time in natural settings, or even just viewing a picture of a natural scene, helps people recover from directed attention fatigue, or the mental tiredness that builds up when we sustain deliberate focus over time. For most kids, that’s most of their day. Natural environments give the brain permission to shift into a softer, more effortless mode of attention (that floodlight or lantern awareness), allowing limited attentional resources to replenish. These restorative effects can persist, making learning and focusing easier long after kids come back inside.

Nature also awakens our sense of wonder. The awe you feel entering an expansive meadow, marveling at the fractals on a pine cone, or even standing on an urban blacktop and staring up at the sky is, perhaps, the best kind of invitation to stop everything and just be. For young people, many of whom are tethered to a steady drip of external, often algorithmic stimulation, that kind of reset is both rare and powerful. And, at a time in life when kids are hyper-focused on social feedback, the natural world offers something different. Animals, plants and open spaces provide a genuine sense of connection with greater ease than other humans sometimes can.

The problem, put plainly

It breaks my heart to see how, as most kids age, their opportunities to move and play outdoors diminish so dramatically.

Since the turn of the century, kids have lost 60 minutes of recess per week, on average. More than 75% of school districts lack any recess policy, and as of 2025, only about 10 states require it — and only for elementary students. By middle school, recess largely disappears and the day becomes a series of sitting still — or getting in trouble when you don’t. Health authorities including the WHO and CDC recommend that children get 60 minutes of moderate-to-vigorous physical activity every day. Most kids are getting less than half that.

Outside of school, kids ages 8–12 spend an average of five and a half hours per day on screens. Teenagers clock over seven. Sedentary time increases by roughly 20 minutes per year as kids age, compounding quietly, year after year. The gap between what kids’ brains and bodies need and what they’re actually getting is real, and it’s widening.

But have no fear! It doesn’t take as much as you think.

The benefits of outdoor time don’t require national parks or full days in the woods. A large-scale study found that just two hours per week outdoors is enough to start reaping meaningful health and wellbeing benefits. You can spread those minutes out however works — a few evenings, a weekend morning, a walk to or from school. The threshold is lower than most parents imagine. You don’t need to engineer a perfect nature experience. You just need to tip the scales a bit.

Bigger kids need a different kind of outdoor time

I’ve also come to realize that it doesn’t always work to get tweens or teens outside the same way we did when they were little. Older kids need their own kind of relationship with the outdoors. Here are a few ideas on what I’ve learned along this journey:

Start smooth. If more outdoor time lands as our idea, we all know how that tends to go. So, I’m trying to start small and let them get into a rhythm. I’m also trying to take a page from the anti-tobacco handbook and give my kids information and nurture a gentle sense of outrage. We know how important time outdoors is to kids, and yet schools and our lives don’t build it in. The unfairness is both important for them to understand and motivating.

I find my kids also respond when I frame nature time as a form of reward or self-care rather than another item on their/our to-do list.

Acknowledge what kids are already doing. If your kids and/or family do engage in outdoor activities together, celebrate that. If your kids are already active in a sport, dance, martial arts or other active pastime(s) — celebrate that too. Once kids feel that what they love and already do is seen and respected, they’re more open to adding something new.

I still use a teacher planner to sketch out the activities each week (occupational hazard), and I find a few minutes every Sunday to review plans with each kid (I have yet to deploy Open Claw agents to automate this, and I’m not sure I ever will—the chats are too good!). Every once in a while, I’ll bring a highlighter to mark the moments of outdoor time (literally “green time”) to make visible the outdoor “wins” and opportunities where kids could build in a little more.

Try both ends of the spectrum. I’ve also found it helpful to look at outdoor time in two different ways: real adventures and simply hanging outside.

On one end: adventures. Teenagers respond to novelty, challenge and the chance to prove something to themselves. A night walk, a new hiking trail, a skate park a few towns over, a fire pit or BBQ with friends — these tap into the social, slightly risky adventures that adolescents are wired for.

It also helps to remember that nature and outdoor adventure exists anywhere there’s earth, sky and other species. You can find it in any neighborhood, local park or just by taking the bus or taking a walk somewhere new. Adventures don’t need to be elaborate or expensive, but they do need to feel genuinely intriguing. A treat after never hurts (for my crew, it’s Dunkin’).

On the other end: simple permission to just be outside. Unstructured, low-key outdoor time is deeply underrated for teenagers. Many of us got copious amounts of it growing up — sitting on a porch, walking somewhere with a friend, hanging out in a backyard. The goal isn’t activity; it’s simply not being inside and not being alone.

You can also just start small: park a little farther from the store, pull over to look at a cool tree; take a short detour through a park. Pack up dinner and move it to a blanket in the back yard or in a local playground or park every once in a while. Encourage kids to walk or bike around with a friend—maybe to get a treat. If that feels like a stretch, agree to meet you back at a spot after some amount of time.

You can also just model this practice yourself. Talk about the time you spent outdoors each day. Notice when a neighbor is walking by and pop your head out to say hi and start up a quick conversation—maybe even linger for a minute or two. Just slowly tipping the balance, bit by bit.

A gentle invitation

If you’re the parent of a 10+ year old, you may feel like you’re losing this battle — that screens are winning, that schedules are winning, that the window is closing. It doesn’t have to.

Two hours a week. A walk. A few minutes of actual sky. An adventure that feels like their idea. Free time with friends in whatever version of the outdoors is accessible to you. Kids who spend time outside — even reluctant teenagers — come back a little calmer, a little clearer, a little more themselves.

That’s worth something. And just a few somethings can add up to a whole lot.
