I'm renting a Hyperbaric Oxygen chamber for the next two months with the aims of improving blood circulation and assisting deep breathing - things that were not attended to following my heart operation over 4 years ago.
The accompanying literature says, 'During hyperbaric therapy, the body is gently placed under pressure (1.5atm for me), creating an environment where oxygen can dissolve directly into the blood, tissue, and other bodily fluids, thereby increasing oxygen levels in the cells dramatically triggering a greater production of energy. This [...] can help support the body's coping mechanism with the effects of aging, stress and other conditions that can leave us feeling less than 100%.'
Its operation is simple but I find that it needs someone outside to help with the zipping (3 zips) and to ensure that I don't fall asleep in there. Recommended usage is up to two 60 or 90 minute sessions per day, depending on how well I get on with the setup. Who knows but it might assist academic studying!
