Melatonin puts us to sleep and keeps our immune systems strong



Melatonin is the timekeeper of the body, allowing for sound and deep sleep. It is secreted by the light sensitive pineal gland that regulates the biological clock and synchronizes the hormone-immune network. It is also produced by the retina and in the gastrointestinal system. Melatonin keeps the body in tune with the circadian rhythm, rising with darkness and falling with light. It is melatonin ( mélatonine )that makes you yawn and feel compelled to sleep when it gets dark, even if you do not want to. Melatonin keeps the rhythm for the body to maintain its balance with the rest of nature and adapt to changing environmental conditions.

Declining level of melatonin ( mélatonine )is central in the aging process of the body. Typically, somewhere in the mid thirties the pineal gland begins to become calcified and melatonin ( mélatonine )production starts to diminish, setting in motion a shift in the way the cells of the body operate. The body moves from a mode of repair and rejuvenation to one of aging and degeneration. This is why maintaining an optimal level of melatonin ( mélatonine )is so important. Degeneration and aging-related diseases such as arteriosclerosis, autoimmunity, depressed immune system, cancer, and metabolic conditions are promoted by the de-synchronization of the hormonal system, and its loss of cyclicality and rhythm.

The connection between melatonin ( mélatonine )and aging was dramatically demonstrated in a study where melatonin ( mélatonine )was added to the drinking water of laboratory animals resulting in an increase in their life spans of 30 percent. Older animals drinking water containing melatonin ( mélatonine )became more vigorous and healthy. In another experiment, pineal glands from younger mice were transplanted into older mice that then lived much longer than expected. Their pineal glands were transplanted into younger mice who then died much sooner than expected.

The invention of the electric light bulb has played havoc with the rhythms orchestrated by melatonin. Production of melatonin ( mélatonine )is cued by the coming darkness of night. When we stay up late with the lights on, night never comes and the whole melatonin-prolactin cycle is thrown off. It is at night that the body recuperates and regenerates tissues and organs, and restores glycogen reserves. When melatonin ( mélatonine )levels stay low, this body maintenance can not take place. This is why it is so important to go to bed close to the time darkness settles in, and to sleep in a room that is completely dark. We have learned to fight the signal from melatonin ( mélatonine )that it is bedtime, especially in the fall when darkness descends so early. We yawn and stretch and turn on even more lights to keep ourselves awake, ignoring the signals of our bodies. The result of such actions is a body in a state of melatonin ( mélatonine )deprivation long before we reach the age of thirty-five.

When the body is able to produce the needed amount of melatonin ( mélatonine )it can directly kill many different types of cancer cells. Melatonin is a naturally produced cytotoxin that easily induces death in tumor cells. It can also retard tumor metabolism and development by lowering the body temperature, as it is a natural inducer of hypothermia. It has also been shown to inhibit the spread of the AIDS virus. And it is protective of all the organs in the body, particularly the pancreas.

Supplemental melatonin ( mélatonine )is available at health food stores and online. It is very inexpensive. According to hormone balancing specialist, Dr. Uzzi Reiss, a healthy pineal gland produces 2.5 milligrams of melatonin ( mélatonine )every twenty-four hours. For him the ideal supplemental level for anti-aging is 1 to 5 milligrams. He prescribes supplementation up to 20 milligrams a day for cancer protection.
