Hyperbaric Oxygen Articles
Practitioner Commentary (Taos, NM):
Having given professionally, Hyperbaric Oxygen at 7,000 feet in Taos and up to 11,000 feet at Taos Ski Valley for over 9 years, I can assure you that Altitude issues are very real and deeply miserable. Visitors often can't predict when altitude shock will happen. Someone might visit Taos every year for decades without an issue, only to have a single trip ruined by sudden altitude headaches, fatigue, brain fog, and severe bloating. Most people don't realize these issues stem directly from elevation—or that Hyperbaric Oxygen can often alleviate them in a single 90-minute wellness session. This article is evidence of that physiological reality. Authored by Tracey Flower and featuring clinical insights from Dr. Joel Dekanich and internist Dr. Dennis Lipton, this publication examines the therapeutic application of Mild Hyperbaric Oxygen Therapy (mHBOT) in high-altitude mountain environments. The report details how pressurized oxygen hyper-saturates blood plasma and cellular fluids to effectively simulate lower elevations, providing rapid relief from acute mountain sickness, elevation headaches, and cellular fatigue. In addition to discussing off-label applications such as post-concussion recovery and athletic performance regeneration, the document highlights the safety profile of the OxyHealth Vitaeris 320 chamber—featuring dual-redundant pressure relief valves, heavy-duty 44 oz urethane construction, and a flawless fire safety record utilizing ambient air compression at 1.3 ATA.
Practitioner Commentary:
Having administered professional Hyperbaric Oxygen Therapy to thousands of individuals over more than a decade across a wide range of health challenges, I consider this to be one of the finest medical overviews of how HBOT functions at a physiological level. What makes this perspective particularly valuable is that it comes from an objective, independent specialist who does not operate an HBOT clinic, but who has observed its clinical impact firsthand in patient outcomes.
Authored by board-certified neurosurgeon Dr. Russell L. Blaylock, M.D., in The Blaylock Wellness Report, this comprehensive medical review details how Hyperbaric Oxygen Therapy (HBOT) reverses tissue hypoxia and restores impaired microcirculation. Dr. Blaylock outlines the fundamental physics of hyperbaric pressure, explaining how elevated atmospheric pressure forces concentrated oxygen to dissolve directly into blood serum and extracellular fluids—bypassing red blood cell transport limitations to reach oxygen-starved tissues. The report highlights how HBOT lowers inflammatory cytokines (specifically TNF-alpha), inhibits destructive microglial hyper-activation in the brain, and promotes long-term microvascular regeneration, offering a robust scientific foundation for its role in traumatic brain injury, stroke recovery, neurological health, and systemic cellular repair.
Practitioner Commentary:
What is the impact of elevation on a tourist vs a local. Although locals do not experience altitude sickness because they have "acclimated" to the elevation, living at altitude has a profound affect upon their physiology. What happens to a tourist when they arrive at high elevation? This brief article explains it all.
Hyperbaric Oxygen Therapy: Biophysics, Henry’s Law & Mitochondrial ATP
Operating at an elevation of 7,000 feet in Taos, New Mexico, ambient barometric pressure is significantly lower, making cellular oxygenation and tissue recovery critical. In this technical presentation, Rebecca Harder—IHA Certified Hyperbaric Technician with over 23 years of professional experience—breaks down the biophysics and cellular mechanisms of Hyperbaric Oxygen Therapy (HBOT). Discover how Henry’s Law drives dissolved oxygen directly into blood plasma, lymph, and cerebrospinal fluid—bypassing red blood cell bottlenecks to reach compromised microcirculation. We examine how this oxygen surplus drives mitochondrial respiration to produce ATP for cellular detox pumps, and how the "Hyperoxic-Hypoxic Paradox" triggers the Nrf2 pathway to upregulate your body's master endogenous antioxidants: Superoxide Dismutase, Catalase, and Glutathione.
Colon Hydrotherapy / Colonics
Articles
Practitioner Commentary:
Over my 23 years of administering professional colon hydrotherapy, I consider this to be the single best medical overview available. It offers invaluable perspective by showcasing how incredible doctors and specialists utilize colon hydrotherapy as a supportive well being modality.
Authored by medical journalist Dr. Morton Walker, DPM, and originally published in the Townsend Letter for Doctors, this report aggregates professional endorsements and case studies from board-certified surgeons, gastroenterologists, oncologists, and rheumatologists integrating colon hydrotherapy into personal care. Featuring insights from board-certified gastrointestinal surgeon Dr. Leonard Smith, MD, clinical professor of medicine Dr. Robert Charm, MD, rheumatologist Dr. Arthur E. Brawer, MD, and urologist Dr. Emil S. Sayegh, MD, the paper details how colon hydrotherapy provides gentle, non-toxic evacuation of metabolic waste, stagnant fecaliths, and accumulated toxins. The report highlights the high standards of FDA-registered colon hydrotherapy equipment—including automated temperature/pressure sensors, back-flow prevention valves, and disposable single-use specula—while demonstrating how purified water hydration gently stimulates natural peristalsis, restores gut mucosal hygiene, and reduces systemic toxic burden.
Featured in Rebecca Harder's published book and sold at medical conferences, Gastra Girl: Saving America One Colon At A Time, this dual-part publication pairs an in-depth physiological analysis by Dr. Thomas Dorman, M.D., with landmark gastroenterological clinical trial data led by Dr. Joseph Fiorito, M.D. (Chief of Gastroenterology at Danbury Hospital). Dr. Dorman explores the bowel as a primary excretory organ, detailing how colonic irrigation enhances enterohepatic circulation, lightens the liver's detoxifying workload, stimulates natural peristalsis, and retrains sluggish colonic tone through gentle mucosal rehydration. Complementing this framework, Dr. Fiorito’s 150-patient randomized clinical trial—presented at the American College of Gastroenterology annual meeting—demonstrates that same-day colon hydrotherapy delivers superior or equal bowel cleansing visualization compared to traditional chemical laxative preps (such as Golytely and Fleet Phosphasoda). The combined research provides robust medical validation showing that colon hydrotherapy is a comfortable, safe, and effective protocol for restoring gut motility, relieving constipation, and supporting systemic detoxification.
Enterohepatic Circulation, Vagus Nerve Tone & Motility
What actually happens in the human body during a professional colon hydrotherapy session? In this clinical breakdown, Rebecca Harder—National Board Certified and IACT Certified Advanced Level Colon Hydrotherapist with over 23 years of clinical practice—explains the cellular biophysics, fluid mechanics, and enteric nervous system reflexes behind bowel hydrotherapy.
Learn how delayed fecal transit triggers enterohepatic recirculation (the re-absorption of deconjugated bile and endotoxins back to the liver), how gentle intraluminal distension stimulates Auerbach’s myenteric plexus to restore natural peristaltic tone, and why decompressing the abdominal vault stimulates vagal sensory afferents to shift the autonomic nervous system out of fight-or-flight into parasympathetic repair.
Infrared Sauna Articles
This comprehensive professional review explores the intersection of vascular cardiology, photobiology, and far infrared (FIR) light therapy, focusing on the protection and repair of the endothelial glycocalyx—the delicate micro-thin gel lining every blood vessel. The paper details how targeted far infrared irradiation upregulates endothelial nitric oxide synthase (eNOS), suppresses pro-inflammatory cytokines and induces protective Heat Shock Proteins (HSP70) to maintain arterial integrity and microcirculation. Furthermore, the document connects FIR therapy to Dr. Gerald Pollack’s research on Exclusion Zone (EZ) water, demonstrating how far infrared light acts as a primary energy source to build structured, negatively charged cellular water along hydrophilic vessel membranes. Highlighting non-thermal molecular pathways—including SERCA2 calcium pump activation and RAAS modulation—the study validates how specialized 100% far infrared protocols (such as the Relax Sauna) support cardiovascular health, deep cellular hydration, and systemic anti-inflammatory recovery
Authored by Rebecca Harder (National Board Certified Colon Hydrotherapist and I-ACT Certified Therapist), this published article was featured as an excerpt in the book Gastra Girl: Saving America One Colon At A Time and distributed by Momentum 98 at national health conferences. The paper draws on 23 years of professional experience to compare near and far infrared wavelengths, detailing why semiconductor-grade Far Infrared (FIR) technology provides superior cellular-level detoxification and metabolic stimulation. Harder examines how raising core body temperature to 98.6°F restores immune signaling, prevents stagnant lymphatic flow, and enhances enzymatic processes. Citing comparative laboratory sweat and urine analyses, the article demonstrates that far infrared sauna sweat contains 15% to 20% heavy metals, dioxins, and fat-soluble toxins (compared to just 3% in traditional hot-air saunas). The piece emphasizes the vital synergy between daily far infrared thermal protocols and colon hydrotherapy to relieve autointoxication, reduce systemic pain, and optimize the biological terrain.
