First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether breathing pure oxygen in a pressurized chamber (hyperbaric oxygen therapy) can help adults with PTSD from combat or terror. Thirty people who had PTSD for at least 4 years and hadn't improved with standard treatments received 60 daily sessions. Researchers used brain scans and questionnaires to measure changes in symptoms, sleep, and thinking.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber)
What this could lead to
If it works, this could offer a new way to ease PTSD symptoms like nightmares and avoidance, especially for people who haven't improved with standard treatments.
What could go wrong
This was a small early study with only 30 people and no placebo group, so results may not be reliable. HBOT also carries risks like ear pain or oxygen toxicity.
