What Nature Naturally Does To Your Nervous System
I grew up outside a small university town in Connecticut, on a dead-end road far from any traffic. Our yard had trees, a vegetable garden, and a river running through the back. In summer the leaves were thick enough that we couldn't see the neighbors' houses — we were inside nature, not beside it. The sounds were birds and water.
I've been finding my way back to that ever since. Time present in nature is a cure — it soothes what aches in the soul. It's also prevention: real, measurable, physical change in the brain and body.
Researchers have been measuring this for years now. Twenty minutes near trees, water, or open green space — what one study called a "nature pill" — lowers cortisol measurably. A 2019 study in Scientific Reports found that people who spent at least two hours a week in natural settings reported significantly better health and wellbeing than those who didn't. Our bodies are part of nature, and nature nurtures us in countless ways.
Different landscapes offer different things:
Forest softens your attention. The light moves, the sound is granular, the air is alive. Walking under a canopy invites a slower stride, a softer gaze. Most of my Maryland students live within ten minutes of a forest trail and forget to take advantage of this.
Ocean and large bodies of water seem to do something specific. Researchers call it "blue space." Watching waves, listening to water — the rhythm is regular but never quite the same twice, which is exactly the kind of input your nervous system finds settling. This is part of why we built our Roatan retreat where we did: thatched bungalows over a quiet bay, the water moving underneath you while you sleep.
Open savanna and big-horizon landscapes do the opposite of what you'd expect — they don't agitate you, they calm you. There's a deep, old part of the human nervous system that exhales at long sightlines. You can see what's coming. Nothing is hiding. This is part of the wellness logic of a slow safari — sitting in quiet stillness, watching baby elephants frolic close enough that you can hear them chewing the grass. Or a mountain lodge in the Dolomites or Bhutan: crisp air, vast sky, a falcon passing overhead.
Jungle and dense forest feel different from open woods. The canopy is layered, the air is humid, the soundscape is loud in the most peaceful way — birds, insects, water moving somewhere you can't quite see. It's enclosed but alive. Many people find jungle profoundly settling, as if the green has folded around them.
A small garden does a smaller version of that holding work. You don't need wilderness. A walled garden in Marrakech, a backyard in Howard County, a planter on a balcony. Twenty minutes inside one is real medicine.
If you want to get more out of your time in nature, three things help:
Leave the phone in your pocket, screen down. Take pictures, fine. But don't scroll. Half the benefit is in not being elsewhere.
Match your pace to the landscape, not your stride. Walk slower than your usual. Stop when something interests you. Look at one thing for longer than feels normal. The nervous system shifts at nature's tempo, not yours.
Stay long enough. Five minutes is better than nothing. Twenty minutes is when the body really starts to drop. An hour changes the rest of your day.
You don't have to travel to do any of this. The walk near your house counts. The bench in the park counts. The pot of basil on your windowsill counts more than you'd think. Get to know your local flower fields and woods by season — lavender in June, sunflowers in August, dogwoods in spring. Visit on purpose.
And when you travel somewhere whose whole job is to do this work on you, the effect is concentrated. My Roatan retreat in February sits over the water; my Kenya retreat next June moves with the rhythm of the savanna. Both let the landscape do what landscapes do.
You don't need anyone's permission other than your own to spend more time outside this week. Make your plans. Invite others if you want. Slow down in nature and breathe.
A few books, if you want to go deeper:
Florence Williams, The Nature Fix — the cleanest single survey of the research
Dr. Qing Li, Forest Bathing — from the Japanese physician behind much of the original forest-bathing data
Wallace J. Nichols, Blue Mind — water and the brain
Sue Stuart-Smith, The Well-Gardened Mind — gardening and mental health, beautifully written
Robin Wall Kimmerer, Braiding Sweetgrass — less science, more soul; a way of being in relationship with the living world
I encourage you to buy from your local independent bookstore. And when you can, read outside.
