Insufficient oxygen also causes subnormal body temperatures. The abundance of oxygen creates better health and well being. Antioxidants are really free radical scavengers and enzyme enhancers. Free radicals are atoms or molecules with unpaired electrons. The production of free radicals in our cells occurs by normal respiration and the assimilation of sugar.
Free radicals are an unavoidable occurrence in biochemical reactions.
Free radicals are the natural product of any chemical reaction and they fit into the bodies overall balance. White blood cells use free radicals in hydrogen peroxide to destroy invading bacteria and viruses. Atoms normally contain an even number of paired electrons. If for some reason an electron becomes separated, it causes an imbalance and becomes a free radical. The unbalanced free radical can damage cells that do not have sufficient enzyme coatings.
