BRAIN AND ENDOCRINE CONNECTION

How The Brain Sends Messages

Our brain manages a number of complicated body processes, breathing, digestion, circulation, growth, reproduction, and repair. The brain utilizes two separated systems to control these processes, the nervous system and the endocrine system.

The nervous system is the fastest out of the two. Two send a message fast, the brain uses the nervous system. The messages are generally brief (such as a few thousandths of a second). The nervous system employs electrical impulses that travel through nerve cells as fast as 650 feet (200 meters) per second.

The endocrine system sends most messages slowly. It uses hormones to produce more long lasting effects. Hormonal messages travel through the blood stream. It may take several hours or days to reach the destination or to effect a change. Endocrine system is a collection of ductless glands throughout the body that secrete hormones directly into the blood stream. These glands include the pituitary, thyroid, thymus, adrenals, pancreas, ovaries or testes, and many others. The function of these glands is to control the internal environment of the entire body.

Hypothalamus

Hypothalamus is known as the brain behind the endocrine system. The main vehicle used by hypothalamus is the pituitary (a pea sized gland that sits under the hypothalamus) to control other glands. The hypothalamus weighs a fraction of an ounce. It is about the size of the tip of our thumb.

For example, when hypothalamus determines that the level of thyroid hormone in the blood need to be increased, it releases a hormone to the pituitary gland instructing it to convey the message to the thyroid gland. The pituitary immediately sends a thyroid stimulating hormone to the thyroid instructing it to release more thyroid. When thyroid receives this message, it will start releasing the thyroid hormone called thyroxin. When this happens, the metabolic rates are speeded up. In the same fashion, hypothalamus controls the other endocrine systems, thus controlling such things as the sugar level in the blood, the body temperature, etc.

Pineal Gland

Pineal Gland is a tiny pine-cone shaped (the name is from the resemblance of the shape of the organ to the pine cone) organ located at the back of the brain, just above the brain stem.

Many scientists believe that pineal gland is the “aging clock” for the body. It appears to act as the body’s timekeeper by keeping the body in sync with the most constant environmental cue we have: the light-dark cycle.

It is the pineal’s job to announce to the rest of the body that it is dawn or dusk, time for the body to be awake and alert, or time to prepare for bed and a rejuvenating sleep. This crucial signal sets complex processes into motion, a cycle that is designed to remain relatively regular and balanced. The circadian rhythm (see below for an explanation) lies at the heart of the state of internal balance and harmony we know of as health. When it becomes disrupted over a long period of time, there may be serious physical and psychological consequences.

At the same time, the pineal gland also appears to act as the body’s pacemaker, a kind of “activities director” for the human life cycle. Scientists believe that the pineal gland, through its major product, melatonin, triggers the start of puberty and regulates reproductive life. When the pineal gland stops giving out its melatonin-directed signals, we grow old because our bodies are no longer able to operate with efficiency or with internal synchronicity.

Melatonin

Melatonin is produced by the pineal gland. Scientists believe that the pineal gland and melatonin are the body’s primary timekeepers-its clock and calendar-imparting information about the time of day, season of the year, and phase of life to the brain and throughout the body. Melatonin is believed to influence the internal processes so that all of the body’s systems work together, in coordination. Should this internal structure become disorganized in any way, the body becomes more susceptible to disease.

Melatonin is produced almost exclusively at night or in a light-free environment. (In fact, it is nicknamed “the chemical expression of darkness” by scientists because of its nocturnal habits.) Blood levels of melatonin are up to ten times greater at night than during the day. This high concentration of nocturnal melatonin led scientists to conclude that the production of this hormone signals to the rest of the body that it is time to sleep. Indeed, melatonin supplements have been used for decades to treat sleep-related problems, such as insomnia, sleep apnea, and jet lag.

In the morning, when we perceive that it is light, melatonin secretion ceases, which stimulates the production of other hormones and hence other body activities to begin. This orderly daily rhythm is of prime importance to our physical condition, intellectual capabilities, and emotional health.

Animals change their behaviors such as reproduction, hibernation, and migration based on the season. It is believed that animals perceive the change of seasons by the patterns of light and dark. The mechanism used to implement this behavior is by the secretion of melatonin. When daylight hours grow shorter during the autumn months, melatonin production in animals automatically increases, helping to make the almost constant sleep of hibernation possible. When daylight hours increase during the spring, the pineal gland secretes less melatonin, triggering a new pattern of physical activity.

The ways in which these seasonal patterns affect human behavior is under intense investigation. Some researchers believe that seasonal melatonin levels may help to explain Seasonal Affective Disorder. Chronobiology is a new science that is concerned with identifying our cycles and internal clocks and seeing how they interact. Such natural rhythms as temperature fluctuations, weather systems, patterns of light and dark are studied to explore how it affects the life cycle of men and women.

Melatonin and Serotonin

Melatonin affects the production and subsequent action of several other hormone in the body. It works in sync with serotonin, a powerful neurotransmitter from which it is derived. Serotonin is involved in several central physiological processes, including pain perception, temperature and blood-pressure regulation, and several neuropsychological functions such as appetite, memory, and mood. Like melatonin, serotonin levels influence a myriad of endocrine activities, including those performed by the hypothalamus and pituitary gland.

Generally speaking, melatonin and serotonin are not active in the body at the same time. As mentioned earlier, melatonin is active at night, serotonin is active in the daytime. Although both tend to moderate endocrine functions, serotonin may also have a negative effect on the cardiovascular system if its levels are too high in the bloodstream. It has been known to cause blood clotting and narrowing of the blood vessels, among other problems. And, unlike melatonin, serotonin levels in the body do not decrease as we age, but instead increase in relation to other hormones and neurotransmitters. Scientists who specialize in the study of elderly and the aging process believe that this age-related imbalance between serotonin and melatonin may play as important a role in the aging process as the lack of melatonin itself, particularly in relation to heart disease. Without melatonin to act as a free-radical scavenger during the night, more damage may occur to blood vessels, thus stimulating the release of more serotonin.

There are three supplements that most folks need – I call these the basics. The forth most important supplement is Enzymes.

  1. Liquid Minerals
  2. Omega 3 oils (essential fatty acids)
  3. Probiotics

Because our food supply is depleted of minerals I find most individuals need minerals. Minerals are the catalysts for many functions in the body. Zinc is responsible for 145 enzyme systems in the body. Absorption is key. We can ingest expensive supplements and not absorb 50% of them. Our Complete Minerals are frequency enhanced for better absorption. We only carry the highest quality of products. I recall when I added minerals to my protocol and I felt like someone shined my glasses!

Omega 3 fatty acids are the second most important supplement. The pure fish oils are important for many functions in the body. These good oils circulate in your system and feed the brain, circulation, muscles, joints, ligaments, the digestive track and more. It is like the oil in your automobile. You would never allow your vehicle to be without oil or the engine will fail. It is the same with your body. Pure Omega 600 is free of mercury and heavy metals which is often found in fish.

Probiotics are the good bacteria that are found in your colon. Lactobacillus is found in the small intestine and Bifidus is the bacteria that inhabit the large intestine. The small intestine is responsible for absorption of the nutrients of your food. The large intestine is where the waste products are stored until you evacuate. Getting your bowels moving is very important. Health is having a bowel movement after every meal. Symptoms of lack of the good bacteria include constipation, acne, digestive issues, Candida, repeated infections. Most individuals are lacking in probiotics and can benefit. Food sources include yogurt, kefir, and cultured products.

Everything in life is about digestion and assimilation. Incompletely digested foods cause histamine reactions. The body reacts to deficiencies and this causes histamines which then cause allergies. We can completely rid the body of allergies if we are digesting and assimilating properly. Identify the root causes and correct the imbalances and optimal health can be achieved.
