Starved of oxygen the body will become ill, and if this persists it will die. I doubt if there is any argument about that. In Japan we now see the regular use of oxygen booths and portable oxygen cylinders because the people realize that the air is so contaminated they are not getting sufficient oxygen from it. Insufficient oxygen means insufficient biological energy that can result in anything from mild fatigue to life-threatening disease. The evidence is overwhelming.
Oxygen plays a powerful, primary role in our health and well-being.
The more oxygen we have in our system, the more energy we produce. Understanding this is more important today than ever before, because of a general deficiency of oxygen intake. Simply the best way to optimize health is to be sure that we oxygenate every cell in our body. The reason they can grow in you, rob your body energy and produce disease is because of the low oxygen level in your cells.
