What is wrong with this idiot? Doesn't he know anything?
I'm no joobz but I do have some training in biology. The only thing a hyperbaric chamber is known to do is to accelerate the healing of distressed tissue. Athletes use it to recover more quickly from sprains, strains, stretched/broken ligaments and broken bones. This effect is caused by the athlete being immobile in the chamber (they're usually asleep) with enriched oxygen to the tissues. Oxygen is the necessary oxidizer for the fuel (food) in your body. When the body needs repair, it needs both more fuel and more oxidizer. Like everything in life, this treatment has a cost. More oxygen in the bloodstream, more free radicals in same. The patient swaps an immediate benefit for a long-term detriment.
This is the same reason that medical experts insist that you lie in bed when you have a cold, a pulled muscle, etc. Get plenty of bed rest. Sound familiar? If you are walking around doing your usual stuff, you are using most of your energy in walking, seeing, thinking etc, instead of using it for healing.
The claim that hyperbaric chambers can do anything other than regenerate tissue is bogus. It will do nothing for ADD, ADHD, depression, AIDS, arthrytis, asthma, etc. It may do something for heart disease and stroke only if tissue repair will help.
Stop believing that idiot book, DOC. It's turning your brain to mush. Maybe a hyperbaric chamber will help that.
