Ear infections are also common, but antiseptic solutions made with aluminum acetate are used to take care of them quickly before the infections can worsen.

Some aquanauts swear that the high-pressure environment, which is 2.5 times the normal pressure at sea level, increases healing times like hyperbaric chambers do, and that cuts can heal overnight.
I think they meant decreases.
