TL;DR
Quick Summary
Forest bathing, or Shinrin-yoku, is the Japanese practice of slowly taking in the forest atmosphere. Research suggests that time among trees can support stress reduction, parasympathetic nervous system activity, and immune function. One of the reasons may be phytoncides — aromatic compounds released by trees and plants. This post explores what forest bathing actually does to the body, why forest air feels so different, and how phytoncide-rich botanicals like black spruce and cypress can offer a daily sensory reminder of the forest, even when you are nowhere near one.

I think about this a lot when I’m in a city.
The way a walk through trees feels different from a walk through a neighborhood, even when the pace and distance are exactly the same.
The way something in the body settles in the presence of old trees.
The way the air feels less like something you are breathing and more like something that is breathing with you.
And the smell... my goodness, the smell.
There is a particular kind of aliveness in a forest that registers somewhere below thought. How your body just knows that it's a part of something bigger.
For a long time, I would have called this “being in nature” and left it there.
But as I learned more about the nervous system, I came across a fun and exciting connection between our internal emotional landscape and that of a forest.
Because in truth, it's an environment your body was shaped by.
And one of the most fascinating pieces of that relationship comes down to something called phytoncides.
Phytoncides are aromatic compounds released by trees and plants. They are part of the plant’s own protective system — its way of defending itself from harmful insects, fungi, and bacteria.
The wild part?
When humans breathe them in, the body appears to respond.
Not metaphorically... Physiologically.
This is part of why the Japanese practice of Shinrin-yoku, or forest bathing, has become so compelling in the world of nervous system and immune research. It gave language to something many of us have felt in our bones long before we had the science to explain it.
The forest was never just scenery. It has always been speaking to the body.

What Is Forest Bathing and Does It Actually Work?
Forest bathing is not hiking, or exercise. It is not trying to get your steps in, beat your last trail time, or accomplish a scenic route before lunch.
Shinrin-yoku translates roughly to “taking in the forest atmosphere.” It is the slow, sensory practice of being among trees, breathing the air, listening, noticing, and letting the environment work on you.
No destination. No performance. No achievement.
Just presence.
And the research on forest bathing is genuinely beautiful.
Studies have associated forest bathing with reductions in cortisol, lower blood pressure and pulse rate, increased parasympathetic nervous system activity, and reduced sympathetic nervous system activity compared with city environments.
Translated out of research language:
Time among trees may help the body shift away from fight-or-flight and toward rest, repair, and restoration.
The forest does not ask your nervous system to try harder. It gives your nervous system an environment where it can remember another way of being.
Because so much of modern wellness is about adding another thing to do.
Another routine.
Another protocol.
Another app.
Another practice to remember when you are already tired.
But forest bathing is different.
The practice is not to dominate your body into regulation. It's to place your body back inside an environment it knows how to receive.

What Are Phytoncides and Why Do They Matter?
This is the piece of the science I find most extraordinary.
Phytoncides are volatile aromatic compounds released by trees and plants. They include compounds like alpha-pinene and limonene, which are found in many forest environments and tree-derived essential oils.
In simple terms: phytoncides are part of the forest’s aromatic immune language.
They are one of the ways trees protect themselves.
And when humans breathe them in, they've been shown to support changes in the immune and stress response systems.
Research led by Dr. Qing Li has explored how forest environments and phytoncide exposure relate to natural killer cell activity, stress hormones, and immune markers. In one study, aromatic volatile substances from hinoki cypress stem oil were vaporized in hotel rooms, and the researchers found that phytoncide exposure and decreased stress hormones may have partially contributed to increased NK cell activity.
Natural killer cells, or NK cells, are part of the body’s immune defense system.
And while this does not mean we need to turn every forest walk into a medical claim, it does mean something important:
The forest is not just “relaxing” because it looks pretty.
It actually gives the body chemical, sensory, and environmental inputs.
Scent is one of those inputs. And scent is powerful because it bypasses so much of our thinking mind.

Can You Get the Benefits of Forest Bathing Without a Forest?
This is the question I care about most.
Because most of us are not walking through ancient cedar groves or boreal forests every morning. (I wish!)
We're in houses, cars, apartments, school pickups, offices, grocery stores, bedrooms, bathrooms, and kitchens.
We are living indoor lives in bodies that were shaped by outdoor worlds.
So can an aromatherapy spray replace a forest?
No.
And I do not think we should pretend it can.
A living forest is not just scent.
It is filtered light.
Birdsong.
Soil.
Moisture.
Microbial diversity.
Wind through branches.
Visual complexity.
Uneven ground.
Temperature.
Texture.
The quiet intelligence of an entire ecosystem.
No spray, oil, candle, or indoor ritual can replicate the full-body experience of being held by a living forest.
The forest is the full ecosystem.
But that does not mean the doorway is closed.
Research suggests that phytoncide-rich aromatic compounds carry some of the forest’s physiological signal even when the full forest is not present. Indoor exposure to hinoki cypress oil has been studied as one way to explore how tree-derived aromatics affect immune and stress markers.
So the point is not that North replaces the forest.
The point is that North offers one piece of the forest signal.
The aromatic piece.
The breath piece.
The pause.
The cue.
The remembering.
When you inhale North, you are receiving botanicals from the same conifer family associated with the aromatic compounds studied in forest bathing research.
Black spruce.
Cypress.
Vetiver.
Lavender.
Rose water.
It is not the same as standing beneath a living canopy. But it's not nothing.
It is a daily sensory echo of something ancient.
A small doorway back to the plant world.
A way to offer your nervous system a signal it was designed to recognize.
Why Did We Evolve to Respond to Forest Air This Way?
Because for most of human history, forest air was simply air.
Our nervous systems did not evolve under fluorescent lights, surrounded by screens, sealed windows, climate-controlled rooms, and constant digital noise.
They evolved in relationship with the living world.
Trees.
Soil.
Water.
Light.
Weather.
Birdsong.
Plant chemistry.
Seasonal change.
The rhythm of day and night.
The human body was shaped by environments rich with phytoncides, natural light variation, microbial exposure, soundscapes, and sensory complexity.
So when we talk about the benefits of forest bathing, we are not talking about a luxury wellness trend. We're talking about restoration of contact with that living ecosystem we were designed by.
How to Practice Indoor Forest Bathing With North
Since you can't exactly recreate the forest, you need to give your nervous system enough of the right signal to begin receiving what it has been looking for.
This is where science becomes ritual.
Here is a simple indoor forest bathing practice.

This is not about pretending your bedroom is a forest. That would be silly (and amazing...).
It's about giving your body a signal it remembers.
The black spruce and cypress in North bring the conifer note — grounding, clearing, forest-like, resinous.
Vetiver brings the root.
Lavender brings softness.
Rose water brings the subtle floral opening.
Together, they create a botanical ritual that is not trying to imitate a generic forest candle.
It's offering a sensory threshold.
A way to pause, breathe, and let the plant world meet you in the middle of your real life.
How cool is that. To have access to a forest in your bathroom, bedroom, car, kitchen, office...
The thirty seconds before the next thing begins.
FAQ: Forest Bathing and Phytoncides
What is forest bathing?
Forest bathing, or Shinrin-yoku, is the Japanese practice of slowly taking in the forest atmosphere.
It is not hiking or exercise. It is not about distance, speed, or intensity.
It is a sensory practice of being among trees, breathing forest air, noticing the environment, and allowing the body to receive the forest through the senses.
Research has linked forest bathing with stress reduction, lower cortisol, lower blood pressure, and increased parasympathetic nervous system activity.
What are phytoncides?
Phytoncides are aromatic compounds released by trees and plants.
They are part of a plant’s natural defense system, helping protect it from harmful insects, fungi, and bacteria.
When humans breathe in phytoncide-rich forest air, research suggests these compounds may play a role in some of the immune and nervous system effects associated with forest bathing.
How long do the effects of forest bathing last?
Some studies suggest that forest bathing can have effects that last beyond the time spent in the forest, particularly related to immune markers like NK cell activity. Research on forest bathing trips has found increases in NK activity after forest exposure, with some effects lasting days afterward.
I would be careful not to turn this into a promise.
The point is not that one forest walk magically fixes everything.
The point is that the body responds to repeated contact with the living world.
Can essential oils replicate forest bathing benefits?
Not completely.
Essential oils and aromatherapy do not recreate the full intelligence of a living forest.
They do not give you the canopy, the soil, the soundscape, the microbial diversity, the filtered light, or the movement of walking among trees.
But tree-derived aromatics do offer one meaningful piece of the forest signal: scent.
Research on phytoncide exposure, including studies using hinoki cypress oil indoors, suggests that certain tree aromatics may contribute to some of the immune and stress-related effects associated with forest environments.
So while essential oils are not a replacement for forest bathing, they are a doorway.
Which essential oils are connected to phytoncides?
Many tree-derived essential oils contain phytoncide-related compounds, especially conifer oils.
Examples include:
Black spruce.
Cypress.
Pine.
Cedarwood.
Fir.
Hinoki cypress.
North includes black spruce and cypress, which is part of why the blend carries such a grounding, forest-like quality.
Is North a forest bathing product?
Not exactly.
North is not a substitute for spending time among trees. But the connection is real.
North contains conifer-derived botanicals, including black spruce and cypress, which connect it to the family of tree aromatics often discussed in phytoncide and forest bathing research.
Used as a daily ritual, North can offer a small, accessible way to bring the sensory language of the forest into the spaces where real life happens.
Not as a replacement for nature but as a reminder.
The Forest Has Always Known
Before wellness trends.
Before research papers.
Before Shinrin-yoku had a name.
The forest was medicine.
Human bodies knew it.
Responded to it.
Were shaped by millions of years of it.
Maybe the forest has always known what modern life keeps asking us to forget:
That the body does not regulate in isolation.
It regulates in relationship.
With air.
Scent.
Soil.
Trees.
Water.
Light.
Rhythm.
Breath.
You may not have a forest nearby.
But the plants are still here.
Their aromatic compounds are still real.
And your nervous system still knows how to receive them.
One breath of something true.
That is where it starts.
You are your own sanctuary.
The tools are simply how you remember.
