I’m currently undergoing Hyperbaric Oxygen Therapy or HBOT every weekday for an old brain injury and it has been amazing! I felt so much relief after just one treatment, and it got me thinking — could this therapy be helpful for people with long COVID or a vaccine injury? I looked into it when I got home and it turns out there are some preliminary studies on this.

Hyperbaric Oxygen Therapy (HBOT) has emerged as a promising adjunctive therapy for addressing the lingering symptoms of Long COVID and potential adverse effects related to mRNA COVID-19 vaccinations. Through mechanisms like stem cell proliferation, detoxification, and enhanced tissue oxygenation, HBOT may support the body’s healing processes and improve quality of life. This article reviews these mechanisms and summarizes recent research findings on HBOT’s benefits in these contexts.

What is Hyperbaric Oxygen Therapy, Exactly?

HBOT involves breathing pure oxygen in a pressurized chamber, which dramatically increases the amount of oxygen dissolved in the bloodstream. This elevated oxygen level enhances oxygen delivery to tissues, promotes detoxification, reduces inflammation, and supports cellular repair — all things that would be super helpful for those looking to heal from long covid or a vaccine injury. Originally used for treating conditions like hypoxia (cells not getting enough oxygen) and non-healing wounds, HBOT is now being investigated as a treatment for post-viral syndromes. Based on its effects and the fact that long COVID and vaccine injury often have similar symptoms, it sounds pretty promising.

HBOT for Long COVID: Mechanisms and Benefits

Persistent Symptoms and the Need for New Therapies

Long COVID encompasses symptoms that linger months beyond the acute infection phase, impacting cognition, energy levels, and physical health. This condition affects a significant proportion of post-infection individuals, necessitating novel therapeutic approaches to manage its wide-ranging effects on daily life.

Mechanisms: Anti-Inflammatory, Neuroplastic, and Cellular Effects

One proposed mechanism of Long COVID is persistent neuroinflammation, possibly due to immune dysregulation and direct effects of the SARS-CoV-2 virus on the brain. HBOT helps counteract these effects by reducing inflammation, promoting neuroplasticity, and enhancing blood flow in affected areas. HBOT’s oxygen-rich environment stimulates angiogenesis (formation of new blood vessels), mitochondrial biogenesis, and stem cell proliferation—all critical for repairing and restoring function in damaged tissues.

Clinical Evidence: Cognitive, Sleep, and Pain Improvement

Studies have shown that 40 sessions of HBOT can lead to substantial improvements in cognitive function, psychiatric symptoms, sleep, and pain management for Long COVID patients. MRI findings show improved brain perfusion, particularly in areas linked to cognition and emotional regulation. These improvements persist at one-year follow-up, indicating that HBOT can offer lasting symptom relief and potentially even structural repair of brain tissues.

HBOT for Vaccine Injury: A New Frontier in Research

Exploring Vaccine Injury Recovery through HBOT

Vaccine-related adverse events have brought forward a subset of patients experiencing prolonged symptoms after mRNA COVID-19 vaccination, with reports of chronic fatigue, cognitive fog, pain, and inflammatory responses. These symptoms may reflect immune dysregulation or an inflammatory cascade similar to Long COVID, suggesting HBOT’s potential as a therapeutic intervention.

HBOT offers a unique area of research for these cases, as it has demonstrated efficacy in alleviating similar post-viral symptoms in Long COVID patients. With its ability to reduce inflammation, promote healing, and support cellular repair, HBOT could play an essential role in addressing post-vaccination injury. Further studies could help identify optimal HBOT protocols for managing these specific injuries and improve understanding of HBOT’s broader applications in post-vaccine care.

Stem Cell Stimulation: Supporting Tissue Repair and Regeneration

One of HBOT’s most notable effects is its ability to stimulate the production and migration of stem cells, which are essential for tissue repair and regeneration. Stem cells aid in rebuilding damaged tissues, including those affected by inflammation or immune system dysregulation. HBOT-induced stem cell proliferation could be particularly valuable for patients experiencing tissue damage or persistent inflammation following vaccination. By supporting the body’s repair systems, HBOT may improve recovery outcomes and restore cellular function in a way that few other therapies can.

Additional Mechanisms: Detoxification and Cellular Health

Oxygenation and Detoxification

HBOT enhances detoxification by flooding the body with oxygen, which helps metabolize and clear toxins more efficiently. This detoxifying effect could assist in reducing residual inflammatory byproducts or foreign particles, potentially associated with vaccine injury. HBOT increases blood flow to hypoxic tissues, where poor oxygen levels may impair detoxification pathways, thereby supporting overall cellular health and resilience in the body.

Telomere Lengthening and Cellular Longevity

Emerging research also suggests that HBOT may positively impact telomere length, which is associated with cellular aging and longevity. Telomeres protect chromosomes from deterioration, but they shorten with age, contributing to cellular aging and inflammation. Studies have indicated that HBOT may lengthen telomeres, thus slowing cellular aging and bolstering the body’s natural repair mechanisms. In cases of persistent post-vaccine symptoms, this anti-aging effect could potentially help repair damaged cells and restore systemic balance.

Safety and Considerations for HBOT Use

HBOT is generally safe with few contraindications, though it is essential to screen for conditions such as untreated pneumothorax. Common side effects are mild and can include ear discomfort or temporary claustrophobia. The studies reviewed reported minimal adverse effects, with participants generally tolerating HBOT well.

Costs and Approved Indications for Hyperbaric Oxygen Therapy

Financial Considerations for HBOT

Hyperbaric Oxygen Therapy can be a significant financial investment, especially for individuals seeking it as an adjunctive treatment for Long COVID or vaccine-related injuries, which are not currently covered by insurance in most regions. In the U.S., the cost of HBOT sessions varies widely, depending on the facility, the pressure used, and the number of sessions prescribed. A single session typically ranges from $100 to $250, and the recommended course for conditions like Long COVID or vaccine injury can involve 20 to 40 sessions, amounting to several thousand dollars in total.

Although HBOT can be cost-prohibitive without insurance coverage, some patients find it worth the investment due to the potential long-term benefits and relief from persistent symptoms. Investigating local HBOT clinics and facilities that offer sliding scales or discounts for multiple sessions may help reduce costs for those seeking this therapy.

Approved Conditions for HBOT Prescription

HBOT is FDA-approved and covered by insurance for specific medical conditions based on substantial clinical evidence of its benefits. Conditions typically approved for HBOT prescription include:

Severe Carbon Monoxide Poisoning
Decompression Sickness (common among scuba divers)
Gas Embolism
Traumatic Brain Injury / Severe Concussions
Diabetic Foot Ulcers (non-healing)
Chronic Refractory Osteomyelitis (persistent bone infections)
Radiation Injury (including soft tissue necrosis and osteoradionecrosis)
Severe Anemia (in certain cases)
Compromised Skin Grafts or Flaps
Necrotizing Soft Tissue Infections (such as necrotizing fasciitis)

These approved conditions benefit from HBOT’s ability to deliver high oxygen levels to damaged tissues, promote angiogenesis, and enhance the immune response. For patients with these indications, HBOT is generally covered by insurance with a prescription, as it is considered a medically necessary treatment.

Conditions like Long COVID and vaccine injuries are not yet approved conditions for HBOT, expanding research could help pave the way for broader coverage if evidence continues to support HBOT’s efficacy in these areas. For now, patients interested in HBOT for these off-label uses should be prepared to pay out-of-pocket for treatment but may find the investment worthwhile given the potential for improved quality of life.

Conclusion: A Valuable Adjunctive Therapy with Expanding Potential

HBOT’s ability to enhance oxygen delivery, promote cellular repair, and reduce inflammation makes it a valuable therapeutic option for Long COVID and a promising area of exploration for managing vaccine injuries. By supporting the body’s natural healing processes through mechanisms like stem cell stimulation, detoxification, and possibly telomere lengthening, HBOT has the potential to address persistent symptoms that impact quality of life. As research advances, HBOT could play an essential role in helping patients recover from both post-viral and post-vaccine conditions, adding a powerful tool to the integrative healthcare landscape.
