It is a highly ordered, self-regulating field of energy processes — a field that is continuously reading signals from its environment, converting those signals into biology (orchestrated information flow), and repairing and regenerating itself when given the right conditions. Most chronic illness, including cancer, metabolic disease, and neurodegeneration, is not a failure of the body. It is a failure of the conditions the body needs to function. My work is to identify what those conditions are for you — and to help you restore them. THE ENERGETICS OF HEALTH FRAMEWORK Every cell in your body is responding to five environmental signals at all times: Light · Water · Magnetism · Resonance · Temperature · Time These signals are received and converted into biology (orchestrated information flow) by four molecular systems we call the four receivers: melatonin, melanin, membranes, and mitochondria. Between the environment and these receivers sits a layer of ionic minerals — sodium, potassium, magnesium, iron, copper, zinc, iodine, calcium, molybdenum, manganese, selenium, boron and more — that conduct, translate, and amplify every signal before it reaches your cells. When any part of this system is disrupted — by artificial light, contaminated water, electromagnetic pollution, nutritional depletion, high deuterium, chronic stress, or circadian misalignment — the entire architecture is affected. Not just one organ. Not just one hormone. The whole system. This is why people with complex, chronic conditions often find that single-target treatments produce only partial and temporary results. They are treating downstream effects while the upstream signal environment remains broken. WHAT A CONSULTATION LOOKS LIKE&nbsp; Every person I work with is different. Your diagnosis, history, goals, environment, and biology are yours alone — and your plan reflects that. A consultation begins with a thorough review of your medical history, current symptoms, labs, imaging, and any prior treatments. Learn about my approach and what to expect here. I look not just at what the numbers say, but at the patterns — what the body is trying to tell us about where the system is under stress. From there, we build a plan organized around the framework above. This typically includes: Environmental calibration — how you manage light, water, EMF exposure, and temperature in daily life Circadian alignment — bringing your daily rhythm back into sync with biological time Nutritional strategy — food quality, timing, and metabolic flexibility; always local, seasonal, and low in the environmental contaminants that interfere with cellular chemistry Targeted therapeutic support — a minimal, purposeful selection of agents (such as astaxanthin, lactoferrin, iodine, ionic minerals, marine plasma, and deuterium-depleted water) chosen for their specific biophysical roles, not as broad-spectrum supplementation Metabolic reset protocols — fasting, fasting-mimicking diet, cold and heat therapy, grounding, and photobiomodulation used as active physiological tools Consciousness and resilience — the internal landscape matters as much as the physical environment; stress physiology, autonomic nervous system coherence, and the evidence base for spontaneous healing are integrated into every plan.Inquire about a consultation WHO I WORK WITH I work with individuals navigating complex, serious health challenges — particularly those who feel they have exhausted conventional options, are looking for a more complete picture alongside their medical care, or want to take an active role in their own recovery. My clinical focus includes: Cancer (integrative oncology support, pre- and post-treatment optimization) Metabolic dysfunction (insulin resistance, obesity, fatty liver, type 2 diabetes) Neurological and neurodegenerative conditions Chronic inflammatory and autoimmune disease Hormonal dysregulation and thyroid conditions Complex cases where no single diagnosis fully explains the picture I work alongside your existing medical team — not in place of it. THE PHILOSOPHY BEHIND THE PRACTICE&nbsp; Modern medicine inherited a model of the human body from 19th-century physics: a machine made of parts, governed by chemistry, understood by taking things apart. That model has produced remarkable tools. It has also produced a blind spot — it struggles with complexity, with emergence, with the body as a field rather than a mechanism. The science has moved. Quantum biology, biophysics, and the study of coherent systems have given us a far richer understanding of how living organisms actually function. Light does not just cause sunburn — it governs metabolic rate, hormonal signaling, and gene expression. Water is not just a solvent — it is a structural and energetic medium whose quality determines the quality of every cellular process. Minerals are not just nutrients — they are ionic conductors that translate electromagnetic signals into biological action. This is not alternative medicine. It is a more complete physics applied to biology — one that takes the body seriously as the sophisticated, self-regulating system it is. My aim is to bring that understanding to you in a way that is practical, personalized, and grounded in the best available evidence — and to walk alongside you as you rebuild the conditions your body needs to do what it already knows how to do.

CANCELLATION POLICYMy cancellation policy requires 48 business-hours notice for any cancellation or to reschedule your appointment. A cancellation fee will be charged if this is not met as this prevents another client from being scheduled. If an emergency arises within 24 hours please contact me as soon as possible. COMMUNICATIONSEmail is the most effective way to communicate with me. Please understand though that email communication is best reserved for simple yes or no questions, I always welcome those. However, if you would like to discuss changes to your recommendations, new health concerns, discuss imaging types and frequency, ask my opinion about information you read online or have more involved questions, I ask that you schedule a follow up consult. PAYMENTPayment is due at the time of service, I accept Zelle, Venmo, credit cards, and bitcoin. Regarding insurance, unfortunately health insurance companies do not honor naturopathic doctors. However, clients with health savings plans or HSA plans successfully process their payments with those. As a courtesy, I provide clients with a superbill which may be filed with your insurance company by you for potential reimbursement or kept for tax deductions. LABS AND IMAGINGYour labs and imaging may be eligible for reimbursement from your insurance, however you’ll need to work directly with your insurance provider to ensure coverage. As every healthcare company and plan is different, I cannot take responsibility for tests ordered that fall outside of coverage. I will always try and obtain the most cost effective tests for you. PRIMARY CAREI am not a primary care physician and require that every client maintains care with a local, primary care doctor while seeking my advice for specialty/adjunctive care purposes. TESTINOMINALS"And thank you for all of this great info. I've been waiting my whole life to meet you!" "I feel good about this plan and I am so thankful for the amazing opportunity to work with you, and the team effort we have!" "Thank you again for our session! I really appreciate the time and thoroughness you put into it before, during, and after. I am optimistic that profound health is ahead!" "You were so thorough, easy to talk to, and terrific all around. A compliment to you from a very picky clinician myself!" "I’m so grateful to have met you and worked with you. You are truly amazing and gifted at what you do and I know that you have made a powerful difference in many people’s lives." "I just have to let you know that I feel so good these days that it can only be described as a transformation. I am very grateful to you and am really excited about being healthy." https://drpetrad.com/Media Mon, 11 Jan 2021 10:51:47 +0000 Dr. Petra https://drpetrad.com/Media 2026OCTOBER 7, 2026<img width="702" height="548" width_o="702" height_o="548" data-src="https://freight.cargo.site/t/original/i/f0921f07721d105f36c45cf21078fb2fb4cb25c7a6a326f1e28f1d2ead672ef1/Screenshot-2026-10-08-at-4.56.08PM.png" data-mid="253059245" border="0" data-scale="95" src="https://freight.cargo.site/w/702/i/f0921f07721d105f36c45cf21078fb2fb4cb25c7a6a326f1e28f1d2ead672ef1/Screenshot-2026-10-08-at-4.56.08PM.png" />Take Back Your Health® with Dr. Myers SEPTEMBER 23, 2026 <img width="728" height="390" width_o="728" height_o="390" data-src="https://freight.cargo.site/t/original/i/e07ffe3fd5ef8b7c9042b7f4662eb9683481022860f76cb2f02e6f4221fe3b57/Screenshot-2026-09-24-at-8.35.13AM.png" data-mid="252592098" border="0" src="https://freight.cargo.site/w/728/i/e07ffe3fd5ef8b7c9042b7f4662eb9683481022860f76cb2f02e6f4221fe3b57/Screenshot-2026-09-24-at-8.35.13AM.png" /> Tend the Terrain Podcast with Dr. Nasha Winters AUGUST 20, 2026 <img width="454" height="446" width_o="454" height_o="446" data-src="https://freight.cargo.site/t/original/i/6c144c83aebb48d7fe4dd00bd2a42354c53751505caac91f0975c7180209b655/Screenshot-2026-08-20-at-2.14.25PM.png" data-mid="251441929" border="0" data-scale="68" src="https://freight.cargo.site/w/454/i/6c144c83aebb48d7fe4dd00bd2a42354c53751505caac91f0975c7180209b655/Screenshot-2026-08-20-at-2.14.25PM.png" />The Physics of Healing: Mitochondria, Membranes &amp; the Glycocalyx with Dr. Petra Davelaar Ep. 315 - The Spectrum of Health MARCH 26, 2026 Presentation for Radiant Healing Together&nbsp; - Sunlight as Signal How Light Governs Melanin, Hormones, and Breast Cancer Risk FEBRUARY 2026 <img width="1972" height="802" width_o="1972" height_o="802" data-src="https://freight.cargo.site/t/original/i/eafdc360538a84f534565efb1bc96dd68af91aaf0f71f0f7e12f516c30992673/Screenshot-2026-03-22-at-9.55.29PM.png" data-mid="246358963" border="0" src="https://freight.cargo.site/w/1000/i/eafdc360538a84f534565efb1bc96dd68af91aaf0f71f0f7e12f516c30992673/Screenshot-2026-03-22-at-9.55.29PM.png" /> Great conversation about the Energetics of Health, check out my Top 12! 2025 DECEMBER 2, 2025 <img width="1282" height="692" width_o="1282" height_o="692" data-src="https://freight.cargo.site/t/original/i/86eaa58969a8d542b47eb8edd84767b915b052eb14aee3144c9215c210d372d0/Screenshot-2025-12-02-at-5.24.22PM.png" data-mid="241338735" border="0" src="https://freight.cargo.site/w/1000/i/86eaa58969a8d542b47eb8edd84767b915b052eb14aee3144c9215c210d372d0/Screenshot-2025-12-02-at-5.24.22PM.png" /> Blessed to have had a great conversation with Katie Deming, MD. about fasting using DDW.

We speak in nouns, so we built a science of things and lost the flow. When we talk about terrain, we are really talking about process. Seen this way, we are light-attuned, electromagnetic, water-based beings — regulated by sunlight, structured by water, and maintained by the dissolved gases and nanobubbles present at every living surface. Our mitochondria are governors of these signals, and our glycocalyx is the charged, hydrated interface where the body meets and negotiates with its environment. Energetics of Health is the framework that draws these threads together — a synthesis of the work of many remarkable scientists, offered honestly, marking clearly what is established, what is interpretation, and what is still frontier.Photo © Andrew McCarthy, Cosmic Background (used with permission).

These are useful pedagogical metaphors. They are not accurate physics. The machine metaphor imports a 19th-century industrial logic into a system governed by 21st-century interface science — and it fails at precisely the questions that matter most clinically: why does cellular energy collapse in cancer, neurodegeneration, and chronic disease? What is actually disrupted, and how can it be restored? A more physically complete framework is now emerging from the intersection of membrane biophysics and colloid science — including the cubic-membrane imaging of Yuru Deng, and the 2026 paper by Barry Ninham, Matthew Battye, and Martha Carlin on the glycocalyx and Parkinson's disease, which offers a significant reframing. THE CELL AS A LIVING INTERFACIAL CONTINUUM The ER, Golgi, mitochondria, plasma membrane, and glycocalyx are not separate units linked by molecular transport. They are different phase geometries of one continuous living interface — a bicontinuous membrane-water-polymer system whose local form reflects local conditions rather than fixed compartmental identity. What distinguishes these apparent structures from one another is not their organelle identity but their local state: lipid composition and saturationionic species and concentration (particularly potassium, calcium, magnesium)degree of glycosylation and sulfationhydration and polymer crowdingcurvature stress and redox environment Change any of these conditions and the geometry shifts. What appeared as a lamellar membrane becomes tubular; what appeared as a mitochondrial crista reorganizes. This is not pathology. This is the system doing what it does — adopting the phase geometry appropriate to its current chemical environment. The glycocalyx is the outer expression of this same logic — not a coating applied to the cell surface, but the polymer-rich continuation of the same structured, charged, hydrated interface extended outward into the extracellular space. It participates directly in ion partitioning, redox interactions, mechanical buffering, and phase continuity with the membrane system beneath it. WHAT MITOCHONDRIA ACTUALLY ARE&nbsp; In this framework, mitochondria are not little generators with pumps embedded in inert membranes. They are dynamic curved membrane-water structures capable of changing topology and local phase organization in response to their chemical environment. What the standard model describes as:electron transport · membrane potential · ATP production · fusion/fission · crista remodeling is better understood as: curvature transitions · charge separation · ion partitioning · redox-dependent interface states · transitions among related phase geometries ATP is not a product in the industrial sense. It is one expression of a living interfacial state — a reflection of whether the bicontinuous structure is holding order. Its formation, localization, and loss all encode the condition of the interface, not merely the output of a chemical reaction. This reframing has a direct consequence for the intermembrane space. The observed ~10 nm spacing between the inner and outer mitochondrial membranes cannot be explained by lipid bilayers separated by bulk water (which would produce ~3 nm). The actual occupant is a glycocalyx-like polymeric domain — heparan and chondroitin sulfate — whose hydration forces, mechanical flexibility, and charge sensitivity determine the curvature conditions of the inner membrane. The glycocalyx is not only outside the cell. It is also inside the mitochondrion. WHERE DEUTERIUM ENTERS This is where deuterium-depleted water (DDW) acquires its most physically rigorous justification. Deuterium (²H), present in normal drinking water at ~150 ppm, is twice the mass of protium. It alters the frequency and lifetime of hydrogen bonds throughout aqueous systems. At the glycocalyx-membrane interface within the mitochondrial intermembrane space — where hydrogen bonding governs the conditions for curvature transitions — elevated deuterium raises the energetic threshold for these transitions, impairing the geometric dynamics through which the interface accomplishes energy transduction. Deuterium depletion restores the kinetic efficiency of these transitions by lowering hydrogen-bond stabilization energy at the interface. This is not a marginal metabolic optimization. Within this framework, it is a direct intervention on the physical conditions that govern whether the living interface holds coherence. Ninham and colleagues trace this isotopic strategy to ancestral bacterial metabolism — specifically NADH-linked fructose-to-mannitol reduction in Leuconostoc, which actively expelled deuterium to generate a depleted interfacial environment supporting rapid curvature cycling. Biological deuterium management is an ancient, conserved feature of energy metabolism. The therapeutic use of DDW restores a capacity the cell already knows how to use.

Ideas this ambitious deserve to be read with a clear sense of what is known, what is inferred, and what is still proposed. We have no product to sell and no dogma to defend. Our aim is to integrate and synthesize the work of many remarkable scientists into a coherent whole — and to do it honestly. That means we will never dress a hopeful idea in the language of established fact, or let sophisticated physics make an unproven biological claim look settled. So across these pages, every significant claim sits in one of four tiers, and where it helps, we mark them — so you always know which register you are reading in. 1. Established. Measured, published, and not in scientific dispute. For example: that lipid membranes can form highly ordered "cubic" geometries; that deuterium — heavy hydrogen — behaves differently in chemistry than ordinary hydrogen. 2. Interpretation. Our reading of what those established findings mean. The observations are real; the meaning we draw from them is a considered argument, open to challenge. For example: that the motion observed in ATP synthase may reflect a cooperative change of membrane shape rather than a mechanical motor. 3. Proposed mechanism. How we think these principles operate in living systems — a hypothesis we find compelling and are actively developing, but which is not yet proven. For example: the mitochondrion understood as a "field governor" that reads and generates the body's signals. 4. Exploratory. The health and therapeutic frontier — where the framework points, and what it may mean for prevention and care. This is the most speculative tier, offered as direction rather than instruction, and always alongside — never instead of — established medical care. For example: strategies around light exposure, deuterium-depleted water, and dietary fats. Holding these apart is not a hedge. It is the discipline that lets a genuinely new paradigm be built on solid ground — and it is how we honor both the science and you, the reader. Read the bold ideas boldly. Just know, at each step, which kind of claim you are holding. Nothing on this site is medical advice. Please make health decisions with your own licensed clinician. &nbsp; &lt;&nbsp; &nbsp; Back to all topics The Nature of Physical Reality &nbsp;&nbsp; &gt;
