Long COVID can leave people struggling with symptoms like fatigue, brain fog, poor sleep, mood changes, and low overall energy — sometimes long after the virus itself is gone. Because long COVID is complicated and varies from person to person, experts are exploring different ways to help. One option that’s gained attention recently is Hyperbaric Oxygen Therapy (HBOT).
What Is HBOT?
HBOT is a treatment where you breathe enriched oxygen in a pressurized chamber. The extra pressure helps your body take in more oxygen than normal, which research demonstrates can:
- Support healing and repair
- Reduce inflammation
- Improve circulation
- Spur brain and nervous system recovery
Patients often say it feels like a calm oxygen “boost,” and many clinics use it for wound healing, decompression sickness, and neurological conditions.
Recent Research — What the Studies Show
Here are some recent studies that give insight into how HBOT helps people with long COVID:
2025 Prospective Registry Study
A large observational study followed over 230 long COVID patients treated with HBOT. It concluded that the majority of patients who opted for HBOT reported a significant and clinically relevant increase in quality of life 3 months after treatment, especially in cognitive symptoms like memory and thinking clarity. The largest increase in scores were energy/fatigue, social functioning, emotional well-being and physical functioning

2024 Long-Term Follow-Up Study
Researchers followed up with patients a year after receiving 40 daily HBOT sessions. The significant improvements achieved in quality of life, sleep, mood, and pain were still present one year later — suggesting benefits can last long after hyperbaric treatment ends.

What This Means for People with Long COVID
Good news:
- Many people report clearer thinking, better energy, less pain and improved daily functioning after HBOT.
- Research shows benefits lasting months after therapy ends.
A Quick Takeaway
Recent studies from 2024–2025 show that HBOT may help many people with long COVID, especially for brain fog, quality of life, and overall well-being. If you’re thinking about HBOT, talk with a qualified healthcare provider to see whether it’s right for your situation.
