Possible Side effects and Disclaimer

First, do no harm, “benefit without harm” (primum non nocere). No action without re-action. Applying these methods in a medical environment reduces, but does not eliminate, the possibility of side effects. Both are complementary, adjunct therapies. Prioritize first the proven basics (exercise, diet, sleep). They are safe, well-tolerated, non-invasive treatments, providing controlled physiological stimulus. All machinery are CE approved. For results, at least 8-10 sessions are usually needed. Like any other scientific method, results vary and are not guaranteed. It is crucial to consult with a qualified healthcare professional before starting any new training or therapy.

HBOT Potential Side Effects

Operating at pressures of 1.5 to 1.8 ATA (Atmospheres Absolute) in a soft-sided or “mild” hyperbaric chamber is a common middle ground between clinical hard chambers and lower-pressure home units. While generally safe, this pressure range requires specific precautions.

The most common side effect is middle ear barotrauma, characterized by ear popping, pain, or a “full” sensation. At 1.5–1.8 ATA, there is also a risk of sinus squeeze if you have congestion, as trapped air can cause discomfort in the forehead or cheeks. Some individuals experience temporary vision changes (typically nearsightedness) after multiple sessions, which usually resolves within weeks of stopping. Less common side effects include fatigue (the “oxygen letdown”), lightheadedness, and rare instances of claustrophobia-induced anxiety.


Contraindications Checklist (1.5-1.8 ATA Soft Chamber)

Before using a soft chamber at these pressures, you should consult a physician—especially if any of the following apply:

  • Untreated Pneumothorax: This is the only absolute contraindication. Pressure changes can cause a collapsed lung to expand dangerously.
  • Congestion/Upper Respiratory Infection: Difficulty equalizing ears or sinuses can lead to painful barotrauma.
  • Severe Asthma or COPD: Air trapping in the lungs can be risky during depressurization.
  • History of Ear Surgery: Specifically procedures like stapedectomy or recent tympanic membrane repairs.
  • Recent Eye Surgery: Specifically if any gas bubbles (gas tamponade) remain in the eye.
  • High Fever: Can lower the seizure threshold, and high-oxygen environments can theoretically increase this risk.
  • Certain Medications: Use of Bleomycin (chemotherapy), Cisplatin, or Doxorubicin may interact negatively with hyperbaric therapy.

IHHT Potential Side Effects

While Intermittent Hypoxic and Altitude Training is generally considered safe when administered correctly, it is not suitable for everyone. Potential risks and contraindications can include:

  • Pre-existing Medical Conditions: Individuals with certain conditions, such as uncontrolled high blood pressure, severe respiratory issues (like COPD or untreated asthma), or significant heart disease, should avoid IHT or use it only under strict medical supervision.
  • Acute Illnesses: IHT is not recommended for individuals with acute illnesses, infections, or during medical emergencies.
  • Pregnancy: The effects of IHT on pregnancy have not been adequately studied, and it is generally advised against for pregnant women.
  • Individual Variation: The body’s response to hypoxia can vary greatly. What is a safe and beneficial dose for one person may be harmful to another. The severity, frequency, and duration of hypoxic episodes are critical factors that determine whether the effects are beneficial or potentially damaging.
  • Severe Hypertension: Sudden changes in Oxygen can spike blood pressure.
  • Lack of Regulation: The devices and protocols used for IHT may not be standardized. Severe or poorly controlled hypoxia can lead to harmful effects, including oxidative stress and other physiological damage.

Comprehensive Disclaimer

IMPORTANT NOTICE: The services, protocols, equipment, and programs offered at Meta Recovery Lab (including Hyperbaric Oxygen Therapy [HBOT], Intermittent Hypoxic Training [IHHT], Intravenous [IV] infusions, NAD+ therapy, and ozone therapy) are classified strictly as complementary, adjunctive, and wellness-supportive modalities. They are not medical treatments, cures, mitigations, or preventions for any disease, medical condition, or pathological state.

1. No Medical Guarantees or “Magic Bullets”

We make no guarantees, explicit or implicit, regarding specific health outcomes, athletic performance enhancements, biological rejuvenation, or longevity benefits. Results vary significantly based on individual biology, baseline health, and compliance. None of our protocols replace traditional, evidence-based medicine or treatments prescribed by your primary physician or specialists.

2. Inherent Risks of Adjunctive & Invasive Therapies

All procedures carry inherent risks.

  • IV & Micronutrient Therapy: Involves venipuncture, which carries risks including bruising, infiltration, phlebitis, localized pain, infection, and rare systemic allergic or anaphylactic reactions.
  • Intermittent Hypoxic Training (IHHT) & Ozone Therapy: Altering oxygen and gas exchange creates controlled physiological stress. Individuals with underlying, diagnosed, or undiagnosed cardiovascular, cerebrovascular, or pulmonary conditions face elevated risks of acute adverse events (including dizziness, vasovagal episodes, arrhythmias, or respiratory distress).
  • Hyperbaric Oxygen Therapy (HBOT): While medical-grade hyperbaric environments are monitored, pressure changes can cause barotrauma (e.g., ear or sinus discomfort, tympanic membrane rupture) or oxygen toxicity in rare instances.

3. Regulatory Status & Off-Label Use

Adjunctive therapies such as IHHT, IV micronutrients, NAD+, and off-label hyperbaric applications are not universally recognized as standard-of-care medical treatments for all conditions by regulatory authorities (such as the Cyprus Ministry of Health or the EMA). They are administered purely as recovery-enhancement and supportive tools under independent clinical supervision.

4. Mandatory Screening & Patient Responsibility

Participation in any program at Meta Recovery Lab is conditional upon full medical disclosure and mandatory pre-screening. However, clinical clearance provided by our attending physicians does not eliminate personal health risk. You explicitly acknowledge that you are undergoing these optional protocols entirely at your own risk.

5. Limitation of Liability

By utilizing the services, facilities, and equipment of Meta Recovery Lab, the client—for themselves, their heirs, and executors—agrees to fully release, indemnify, and hold harmless the facility, its owners, directors, medical doctors, nurses, staff, and contractors from any and all liability, claims, damages, or legal actions arising out of or connected to participation in these optional programs, barring instances of proven gross negligence.

Always consult your personal physician or attending specialist before beginning any new wellness regimen, modifying prescribed medications, or undertaking physical stressors like hypoxia or hyperbarism.
