Skin to earth. That's it. Grounding is one of the simplest, most accessible practices in this library, and it sits right at the heart of Taha Whenua: connecting to the land is both a physical act and something much older than that.
What the research says
Grounding, also called earthing, is the practice of making direct physical contact with the earth's surface. The theory is that the earth carries a mild negative electrical charge, and direct skin contact allows free electrons to move from the earth into the body, where they act as antioxidants and support the body's bioelectrical systems.
The research base is still developing and relatively small, but what exists is promising. Studies have found associations between regular grounding and reduced inflammation markers, improved sleep quality, reduced cortisol levels and stress responses, faster wound healing, and improved heart rate variability, a marker of autonomic nervous system health.
That last one matters particularly in concussion recovery. Heart rate variability reflects how well your autonomic nervous system can shift between activation and rest. After a concussion, that flexibility is often reduced. The nervous system gets stuck in a heightened state and struggles to come down. Anything that genuinely supports that downshift is worth paying attention to.
From a Te Whare Tapa Whā perspective, Taha Whenua is understood as foundational to wellbeing. The land is not backdrop; it is relationship. Connection to the whenua grounds us in something outside ourselves, something that was here before us and will be here after. Grounding practices are one of the most literal expressions of that relationship available to us in daily life.
Gardening: grounding with an extra layer
Hands in soil is earthing too, and it turns out there is more going on than just the electrical connection. Soil contains a bacterium called Mycobacterium vaccae, a harmless microbe that the body absorbs through skin contact, inhalation, and minor cuts when you are digging, planting, or weeding. Research from the University of Bristol found that M. vaccae activates neurons in the brain that produce serotonin, the same neurotransmitter that antidepressant medications target, through a completely different pathway and without side effects.
Cancer patients being treated with M. vaccae unexpectedly reported improvements in mood, quality of life, and cognitive function, which prompted researchers to investigate the mechanism. The findings suggest that contact with biodiverse soil environments has a direct and measurable effect on brain chemistry. Gardeners have always known this intuitively. Now there is a reason.
For anyone in concussion recovery managing low mood, anxiety, or cognitive fatigue, the combination of being outside, having hands in earth, doing something slow and purposeful, and absorbing this soil bacterium is a genuinely useful stack. Gardening does not require fitness or speed. It can be done in short windows. It produces something tangible. And it connects you to the land in a way that is both grounding in the earthing sense and grounding in the deeper Whenua sense.
How to do it
For earthing specifically, the main thing is skin-to-earth contact: bare feet on grass, soil, sand, or rock. Concrete and asphalt do not conduct well. Indoors on carpet or wood does not work. You need the actual ground.
- Standing: feet shoulder-width apart on grass, bare feet, just present. Some people find it helpful to imagine roots growing down through the layers of the earth beneath them. This is a way of directing attention toward the body and away from whatever is cycling in the mind.
- Lying down: on grass or sand, letting the whole back of the body make contact. Particularly useful for nervous system settling. If your symptoms mean lying outside is uncomfortable, even sitting with feet flat on earth works.
- Barefoot walking: slow, barefoot walking on grass or beach. The movement adds a gentle vestibular component, useful if balance and coordination are part of your recovery picture.
- Gardening: bare hands in soil, weeding, planting, turning compost. No gloves needed for the M. vaccae effect. Even a pot of herbs on a balcony counts.
None of this changes your physiology immediately or dramatically. But a few minutes of it regularly, particularly when you are feeling overloaded or overstimulated, can be genuinely calming. Even if you are somewhere with limited green space, a small patch of grass, a beach, a park, or a garden bed all work just as well as a forest.
The scientific evidence is early and the mechanisms are still debated. But the broader evidence on nature contact and nervous system regulation is substantial. Even if the specific electrical mechanisms turn out to be more complex than current theory suggests, standing barefoot outside or putting your hands in soil in a calm environment is unlikely to do anything other than good. And for a nervous system that spends most of its time indoors, on hard floors, insulated from the earth by rubber-soled shoes and artificial light, it is a genuinely different input.
I live near the beach. When things are hard, that is where I go. Not always for a swim: sometimes just to stand on it. Feet in the sand, wind off the water, the sound of it. Something shifts. I don't fully understand the mechanism and I don't think I need to.
In the harder years of my recovery, I spent a lot of time indoors, resting, managing symptoms, trying not to overload my system. The irony is that cutting myself off from the outside world was probably adding to the problem. Getting outside, even briefly, even just to the back lawn in bare feet, became part of how I learned to bring my nervous system back down.
I also renovate, and we have a garden. There is something about having your hands in soil that is completely different from any other kind of physical activity. Slower. More grounded, literally. On the days when screens were too much and movement felt like too much, I could still go outside and do something in the garden for twenty minutes. It felt purposeful without being demanding. Now I know about M. vaccae, I think that quiet satisfaction had a biochemical component I was not aware of at the time.
Grounding is one of the things that costs nothing, takes almost no energy, and does not require you to be well enough to exercise. On the days when even a walk felt like too much, I could still stand outside for five minutes. That felt like something I could always do.
