Hyperbaric oxygen at home

The trials disagree, and none tested a home chamber.

Hyperbaric chambers raise the air pressure so you breathe in more oxygen; soft home versions are now sold for recovery. Short answer: a Cochrane review of placebo-controlled trials found muscle soreness was worse, not better, when the treatment started straight after exercise, while a 2026 review found faster recovery without saying its trials used a sham. We found no study of a home chamber. Ask a doctor first if you have lung, ear or sinus problems.

What the research shows

Grades are calculated from the studies listed, by fixed rules.

Mild hyperbaric oxygen improves sleep and thinkingEarly evidence
One trial in men living at 4,300 metres, where the air is thin — it says nothing about sleep at sea level, and was not blinded.
- Open-label randomized trial, 60 people, 1 weeks (2026) — primary outcome: improved. Funder not checked.
Hyperbaric oxygen speeds recovery from muscle soreness after trainingTested — no effect found
The two pooled analyses disagree. The Cochrane review found soreness was worse, not better, when hyperbaric oxygen began right after exercise; a 2026 analysis of ten trials found faster recovery but does not say its trials used a sham. Both pooled small trials, mostly in clinic chambers.
- Pooled analysis of randomized trials, 219 people (2005) — primary outcome: worse than placebo. Funder not checked.
- Pooled analysis of randomized trials (some against usual care, not a placebo), 299 people (2026) — primary outcome: improved. Funder not checked.

We found no study of this chamber. The recovery trials above used clinic chambers and still disagree with each other. Ask what pressure a home chamber reaches; and anyone with lung, ear or sinus problems should check with a doctor before using one.
