Is it possible that hyperbaric oxygen chambers can help your general health long-term?

Maybe: There are no studies to prove long term well being is enhanced but perhaps someone will investigate and report their findings

Hyperbaric: No proof that it has any affect on your general health long-term; of course, unless it was used to cure a wound or condition that would have affected your life adversely.

No proof: There is no proof that hyperbaric oxygen therapy prolongs life, improves "general health", or gives you superhuman strength. While it it is used for treating certain conditions, there have not been many studies looking at possible long-term effects. Prior to starting hbot, all patients should be evaluated by a hyperbaricist & treated only for known uses, avoiding unnecessary risks where possible.
