Effects of Hyperbaric Oxygen Therapy: Improving Sleep

I. Why Does Hyperbaric Oxygen Improve Sleep?

1. Rapidly increases blood oxygen concentration

   In a high-pressure environment, breathing pure oxygen significantly increases dissolved oxygen in the blood. The brain and nerve cells receive sufficient oxygen supply, reducing fatigue and hypoxia-related insomnia.
2. Improves cerebral microcirculation

   Many cases of difficulty falling asleep, frequent nighttime awakenings, and early-morning awakenings are caused by insufficient cerebral blood flow and brain cell hypoxia.

   Hyperbaric oxygen can:

• Dilate cerebral blood vessels
• Improve cerebral microcirculation
• Alleviate brain tissue edema and nervous tension

3. Regulates neurological function

• Stabilizes the autonomic nervous system (sympathetic/parasympathetic)
• Relieves anxiety, tension, and neurasthenia
• Helps fall asleep faster, prolong deep sleep, and reduce nighttime awakenings

II. Which Sleep Problems Respond Better?

• Difficulty falling asleep, frequent dreaming, easy awakening, early awakening
• Insomnia caused by brain fatigue and overuse
• Poor sleep due to anxiety and high stress
• Light sleep caused by snoring and mild hypoxia

III. Brief Summary

Adequate oxygen supply → No brain hypoxia → Relaxed nerves → Faster sleep onset, deeper sleep, longer sleep duration
