We are not visitors here; we came out of this earth. You are the essence of nature. Whenever you are relating with someone or something, are you amplifying? Are you giving more energy into it or are you taking out of it?
Summary
- Air quality is a primary health driver; as humans breathe 10,000 liters daily, the environment acts like a fish tank where clean air is essential for optimal biological function. - Consuming fresh spring water from the source provides living bacteria and natural gases that support health in ways that processed, UV-treated, or filtered water cannot replicate. - Growing plants fosters a direct relationship with nature that goes beyond theory, allowing for a better understanding of how plant molecules modulate human epigenetics and immune responses. - Fungi serve as a biological communication network and an essential immune ally, offering potent antibacterial and antiviral compounds that help the human body adapt to environmental stressors. - Technology represents a new kingdom of life that externalizes the internal world, requiring a balance between digital tools and primal needs like sensory awareness and nature immersion.

Decoding Symbiotic Relationships With Your Environment
At Biohacker Summit 2018 Tallinn, Jaakko Halmetoja Framed Health As A Daily Negotiation With Air, Water, Plants, Fungi, And Technology
On 15 September 2018 in Tallinn, Estonia, Jaakko Halmetoja took the stage at **Biohacker Summit 2018 Tallinn** with a presentation titled **Decoding Symbiotic Relationships With Your Environment: Elements & Kingdoms Of Life** and delivered something more expansive than a wellness talk. It was a plea to remember that human health does not begin in a supplement bottle, a biometric dashboard, or a productivity protocol. It begins in relationship.
Halmetoja, the Finnish nutrition and wellness expert known for a relentless speaking schedule and a decade spent tracing unusual food ingredients and emerging health technologies across the world, argued that modern people had drifted into a dangerous illusion: that nature was somewhere else, a destination to visit, rather than the biological ground of who they were.
“We are not visitors here,” was the underlying message of his talk. Humanity, he suggested, had not stepped onto Earth as a temporary guest. It had come out of it.
The First Symbiosis Was Human
Halmetoja opened not with forests or minerals, but with people. Symbiosis, he reminded the audience, was not only microbial or ecological. It was social. The quality of an interaction depended on intention, on whether one arrived to amplify life or drain it.
“Think about whenever you are asking somebody how they are feeling: do you actually mean it?” he said. “Are you actually interested in that person or are you just thinking about something else?”
In that question sat a broader thesis. Wellness, in Halmetoja’s framing, was not only biochemical. It was moral, relational, attentive. A healthy life was partly built from the sincerity of contact, from the difference between merely performing care and actually offering it.
Air Came First
From there, Halmetoja moved to what he treated as one of the most neglected truths in health culture: air quality.
“The quality of air is primary,” he said. “It impacts your health and your mood more than anything else in your immediate environment. If you do not have a filter, you become the filter.”
It was a line sharp enough to linger. In a culture often obsessed with fine-tuning food, he argued, people ignored the substance they consumed most. Humans breathe roughly 10,000 litres of air a day. For Halmetoja, that fact should have reordered the hierarchy of concern.
He likened the human environment to a fish tank. Feed the fish the finest food in the world, he suggested, and it still would not thrive in dirty water. In the same way, no amount of nutritional sophistication could fully compensate for stale, polluted, badly ventilated air.
This was not merely a technical point. It was a criticism of modern life itself, of offices, sealed interiors, and urban spaces built with little regard for the body’s ancient needs.
Plants Were Not Décor, But Kin
Halmetoja tied air immediately to the plant kingdom, not as a sentimental add-on, but as a living partnership. Humans exhale carbon dioxide. Plants transform it into oxygen. The relationship was elemental, reciprocal, older than civilisation.
In modern interiors, he said, bringing plants into workspaces was more than aesthetic styling. It was an attempt, however partial, to restore the habitat to which human biology remained tuned. He invoked the image of a zoo animal, enclosed in an environment that only crudely imitates the wild conditions under which it evolved. Modern people, he implied, were not so different.
His challenge to the audience was practical and intimate: grow something. Even one aloe vera plant, he said, could begin to change the relationship from abstraction to direct experience. Reading about plants was not the same as knowing them. Cultivation created contact, and contact created understanding.
He went further, borrowing from a line of botanical thinking popularised by writers such as Michael Pollan: perhaps plants had not simply been used by humans. Perhaps they had, in their own way, used humans to spread their genes across the world. The provocation mattered because it overturned the fantasy of human dominance. Nature was not passive. It acted back.
Water As Biology And Metaphor
Halmetoja spoke about water with a mix of reverence and impatience. He seemed struck by how much scrutiny people were willing to apply to coffee beans, while paying relatively little attention to the water beneath everything.
For years, he said, he had preferred spring water taken directly from the source, not the sanitised, treated, commercially packaged approximation of it. What mattered to him was not only mineral content or taste, but vitality: dissolved gases, living bacteria, the sense of contact with something unprocessed and old.
“When you observe the elements deeply, you start to understand what they are showing inside of you,” he said. “Water is a teacher of flow and solutions; when your boundaries dissolve, you start to see yourself from a very different angle.”
Here the talk drifted into a philosophical register without losing its bodily anchor. Water was chemistry, yes, but also archetype. It became a way of thinking about adaptation, surrender, and permeability. To seek out a spring, in Halmetoja’s view, was not only to improve intake. It was to reconnect with source, with geological time, with the idea that health might still contain mystery.
The Microbial World Was Not Beneath Us, But Within Us
Again and again, Halmetoja returned to diversity, especially microbial diversity. Processed food, modern sterilisation, and indoor life, he suggested, had narrowed the ecological richness of the human body. Gut, skin, mouth, and immune system were all shaped by the microbial relationships created through food, water, and air.
His answer was not nostalgic purity, but deliberate reintroduction. Fermented whole foods, synbiotics containing both probiotics and prebiotics, and closer contact with living environments all formed part of his vision of repair.
This was the deeper logic of his presentation. The body was not a sealed unit. It was an ecosystem in conversation with other ecosystems. To damage that conversation was to damage health itself.
Forests Repaired The Mind That Cities Frayed
One of the most resonant passages of the talk came when Halmetoja turned to nature immersion, particularly the Japanese practice of forest bathing, or shinrin-yoku. In his account, time in nature functioned as a corrective to the cognitive violence of contemporary life.
“It is vital for our cognitive ergonomy that we go into nature to reshape the mental architecture that is bombarding us,” he said. “We must go back to the mirror of nature that reflects our biological past.”
The phrase “cognitive ergonomy” was telling. Halmetoja was speaking to an audience steeped in optimisation culture, but he bent its language toward something softer and older. Forests were not leisure accessories. They were environments that recalibrated attention, scent, rhythm, nervous system response, and sensory awareness.
He urged people to sharpen their senses, especially smell, and to become more alert to the signals moving through natural environments. The body, if given the chance, could still read them.
Fungi Became A Lesson In Intelligence
From earth, Halmetoja moved to fungi, one of his most animated subjects. Fungi, he said, were not marginal curiosities. They were evolutionary allies, immune educators, and communication networks. Echoing a now familiar idea in ecological thinking, he described mycorrhizal systems as “nature’s internet”.
He was fascinated by the fact that humans share a deep evolutionary lineage with fungi, and by the pharmacological potency they have developed through long combat with bacteria, viruses, and rival fungi. Many of the compounds modern medicine prizes, he noted, emerged from precisely those ancient struggles.
For Halmetoja, mushrooms such as chaga, reishi, shiitake, maitake, coriolis, and cordyceps represented more than supplements. They offered information, biochemical strategies, and a way for the body to adapt to environmental pressure. They were examples of nature not as backdrop, but as teacher and collaborator.
Technology Was The New Skin
The final turn of the presentation was perhaps its most contemporary. Halmetoja asked the audience to consider technology as a new kingdom of life, or at least as something approaching one. In this framing, tools were no longer external instruments alone. They had become extensions of sensation, identity, and mediation. Technology was a second skin.
“Technology is a huge mirror through which we are externalizing our internal world,” he said. “We are moving into an age where we turn our minds inside out, using the tools we create to feedback into our own experience.”
It was not a denunciation. Halmetoja was too interested in innovation for that. Instead, it was a warning against imbalance. If the future was increasingly digital, then survival, vitality, and sanity would depend on keeping hold of the primal systems that had shaped the human organism long before code, screens, and smart devices arrived.
Air, water, heat, cold, microbes, plants, forests, fungi: these were not quaint relics of a pre-technological life. They were the enduring conditions of human function.
A Philosophy Of Health Rooted In Attention
By the end of the talk, Halmetoja had assembled a worldview that was part biology, part ecology, part spiritual anthropology. Yet its force came from its simplicity. Health, he argued, was not found only in intervention, but in attention. To posture, breathe deeply, grow a plant, seek cleaner air, notice water, enter a forest, eat fermented foods, expose the body to heat and cold, and cultivate sensory awareness: these were not lifestyle ornaments. They were acts of re-entry into a living system.
What Jaakko Halmetoja offered at **Biohacker Summit 2018 Tallinn** was a challenge to a certain strain of modern self-optimisation that tries to engineer vitality while forgetting the environment that makes vitality possible. The body, his audience was reminded, was never separate from the world around it. It was a porous expression of that world.
And if there was one lesson that outlasted the stage lights and the conference setting, it was this: the future of human wellbeing may depend less on escaping nature than on remembering, with humility, that we were nature all along.
