Sub-Optimal Hormone Level Theory Of Aging

Oxidation is a process where atoms or molecules combine with oxygen. Combustion is an example of oxidation reaction. Whenever oxidation reaction takes place with metals like iron, rust is formed as a byproduct. When oxidation reaction occurs in people, it is what we call aging. Inside the human body, there are free radicals or molecules that are missing one electron. If an oxygen molecule loses one electron, it becomes a single oxygen atom that needs one electron. The single oxygen atom would try to steal or donate its electron on a nearby molecule. In this way, free radicals disrupt the normal function of a cell. If DNA is near a free radical, mutation occurs. Over a period of several years, free radical damage accumulates inside the body which causes aging. Free radicals can be also ingested by smoking, ingesting certain foods, polluted water and air, exposure to x-rays and other poisons.

When we grow old, some hormones start a steep decline which marks the beginning of the visible signs of aging. Hormones that decline with age include human growth hormone, melatonin, DHEA, androstenedione (testosterone, estrogen, and progesterone. The levels of insulin also rises as we age, this causes diabetes in older people. There is also an increase in the stress hormone cortisol which causes the muscles to wither. Human growth hormone which is necessary for the growth of tissues slows down as we age. Testosterone, estrogen, and progesterone have other important purpose. They give us sex drive; helps build muscle, health skin tone, makes strong bone and keep our mind
