Effects and Mechanisms of Hyperbaric Oxygen Therapy on Relieving Fatigue

I. Core Effects on Fatigue

1. Rapidly relieve mental fatigue
   • Alleviate dizziness, drowsiness, poor concentration, and memory decline.
2. Relieve physical exhaustion
   • Reduce muscle soreness, weakness, and slow recovery.
3. Improve sleep and fight fatigue fundamentally
   • Accelerate falling asleep, deepen sleep quality, and enhance refreshment after waking.
4. Accelerate recovery after intense work or exercise
   • Reduce lactic acid accumulation and shorten recovery time.

II. Mechanisms of Action

1. Forcefully supplement oxygen to resolve hypoxic fatigue

• Under normal pressure: Oxygen is mainly carried by hemoglobin.
• Under high pressure: Oxygen can directly dissolve in plasma, tissue fluid, and cells.
  → Significantly improve systemic oxygen supply and quickly relieve hypoxia-related fatigue.

2. Rapidly clear lactic acid and metabolic waste

• Improves the efficiency of aerobic metabolism.
• Accelerates the decomposition and excretion of lactic acid.
  → Rapidly reduce feelings of fatigue.

3. Repair damaged cells and reduce inflammation and oxidative stress

• Insufficient cellular energy.
• Excessive free radicals.
• Mild chronic inflammation.

• Promotes mitochondrial function (the "power station" of cells).
• Enhances antioxidant enzymes.
• Reduces tissue micro-inflammation.
  → Repair fatigue at the cellular level.

4. Improve cerebral blood supply and oxygenation to relieve mental fatigue

• Increase oxygen partial pressure in brain tissue.
• Improve cerebral microcirculation.
  → Enhance mental clarity, concentration, and thinking speed.

5. Regulate nerves and endocrine to improve chronic fatigue syndrome

• Reduce excessive sympathetic nerve excitement.
• Relieve anxiety and tension.
• Regulate stress hormones such as cortisol.
  → Transition from a state of tension and exhaustion to relaxation.

III. Suitable Population

• People with long-term staying up late, overtime, and mental exhaustion.
• Those with slow post-exercise recovery and muscle soreness.
• People with chronic fatigue and constant sleepiness.
• Those with insufficient cerebral blood supply, dizziness, and easy tiredness.

IV. Important Reminders

• HBO is a medical procedure and must be performed in regular hospitals or institutions.
• It is not suitable for people with pneumothorax, severe emphysema, cold with nasal congestion, untreated tumors, etc.
• It cannot replace sleep, rest, and nutrition, but only serves as a powerful auxiliary method.
