The Pineal Gland – A Shining Clock for the Inner Clock

The ancient Greeks were well aware of the importance and anatomical location of the pineal gland. While the Greek physician and philosopher Galen considered the pine cone-shaped gland to be responsible for blood circulation, many of his colleagues believed it to be “the first instrument of the soul.

Nearly 2,000 years later, the fascination with this small gland in the brain has not waned. It has long been scientifically proven that it is responsible for the production of the sleep hormone melatonin, making it an important clock for our physical, mental and spiritual health.

What is the Pineal Gland and Where is it Located?

The pineal gland – also known as the glandula pinealis or epiphysis – is an endocrine gland located in the midbrain. Measuring only five to eight millimeters, about the size of a small grain of rice, it is located in the center of the skull at about the same height as the eyes. No wonder it is also called the third eye and has been associated with higher human consciousness for many millennia. This inner eye is said to allow us to “see” on an emotional level.

Its shape is also unusual: it strongly resembles the cone of a pine cone and thus owes its distinctive name to this fruit.

What Does the Pineal Gland Do – What are its Functions?

Although located in the brain, the pineal gland is an important part of the endocrine system, which controls important bodily processes such as metabolism, growth, and sexual development. By converting nerve signals into hormone signals, the pituitary serves as an important link in the system, and because of its central location and good blood flow, it also serves as a clock for all the other glands. In addition, this small powerhouse has another extremely important function. It is responsible for the production of the sleep hormone melatonin. The state of our sleep-wake rhythm and how well we sleep therefore depends to a large extent on the state of the pineal gland.

The Pineal Gland and Melatonin Production – how Does It Work?

Simply put, our pineal gland converts the hormone serotonin, which it produces during the day, into the sleep hormone melatonin at night. Both are neurotransmitters (the body’s own messengers) that act as connectors in all of the body’s nerve cells. While serotonin is also known as the “happy hormone” and is responsible for relaxation and mood elevation, melatonin regulates our sleep patterns, the quality of our sleep and, of course, how we fall asleep.

Not surprisingly, our melatonin levels peak at night. It’s highest in the blood between two and three in the morning, and it steadily declines as light hits the retina – even when your eyes are closed. Sleeping in a dark room is therefore highly recommended for a restful night, as this is the main way in which the depth and quality of our sleep is controlled.

When this sleep-wake cycle is disrupted and there is a melatonin deficiency, it usually results in sleep problems, exhaustion and fatigue. The result: our biorhythms are out of balance and we also suffer from lethargy and listlessness, difficulty concentrating, and low performance. Finally, restful and good quality sleep has an exceptionally strong antioxidant potential. It is precisely during the nightly rest phase that cellular damage can be regenerated and our body can replenish the energy it needs for the day.

It is therefore not surprising that sleep disorders are associated with a higher risk of autoimmune diseases and depression, as confirmed in 2003 by a long-term Taiwanese study involving almost 85,000 participants.*

Fountain of Youth Pineal Gland?

Another exciting fact is that anti-aging researchers in particular see a clear connection between declining pineal gland activity and the resulting reduced melatonin production during the aging process. This is understandable because, as mentioned above, cell damage is primarily repaired at night and harmful free radicals are fought with antioxidants such as melatonin. A targeted supply of melatonin as a highly effective anti-aging agent can be a sensible approach if you want to delay aging. Of course, this should always be done in combination with a healthy lifestyle. A balanced diet, plenty of exercise, good water and, of course, a positive attitude are just as important in combating the natural aging process.

The Third Eye: Spirituality and the Pineal Gland

If you look at the seven energy centers (chakras) of our body, you will immediately notice the shape and position of the so-called brow chakra: the pine cone-shaped energy point is located in the middle of the head and at the level of the eyebrows. This is exactly where our pineal gland is located, which is why it is also called the “eye of the soul” or the “third eye”. The pineal gland is the gateway to higher and more subtle levels of consciousness, which must be activated through special meditations, high frequencies and a certain inner attitude. The fact that our pineal gland has shrunk considerably in the course of evolution (from the original three centimeters to a tiny five to eight millimeters) and is now often heavily calcified due to environmental toxins, fluoride and our “modern” lifestyle, is said to reduce the possible spiritual potential.

Our 8 Tips for an Active(r) Pineal Gland

To keep your pineal gland active and producing valuable melatonin, here are some helpful tips.

  1. Avoid fluoride, as these salts of hydrofluoric acid are the biggest enemy of the pineal gland. This substance is often found in common toothpastes, mouthwashes, and even many mineral waters. Switch to fluoride-free toothpaste and, ideally, filtered, pure water.
  2. Aluminum, mercury, caffeine, tobacco, refined sugar, highly processed foods, soft drinks and radiation fields are also known to promote pineal calcification. Try to avoid these substances.
  3. Effectively support your body’s own detoxification, e.g. with PektiCLEAN®, ChitosaCLEAN colon or SulfoCLEAN®. Once toxins such as heavy metals have been bound and eliminated, your sensitive pineal gland will be happy, as will your entire organism.
  4. Breathe consciously, deeply and with concentration – ideally as part of a daily meditation. Concentrate on the area between your eyes, your third eye, and feel within yourself. Relaxation and serenity are valuable for the production of serotonin and melatonin.
  5. Enjoy the sun’s rays for at least 15 minutes a day without sunglasses! The light energy fires up your pineal gland and stimulates serotonin production.
  6. Make sure you have a good sleeping environment, such as a darkened room, and avoid using technological devices such as smartphones, tablets, computers, and televisions. Unfortunately, backlighting interferes with melatonin production.
  7. Warble and sing to your heart’s content, as the vibrations created stimulate your pineal gland immensely.
  8. Add nutrients such as magnesium, but especially boron (borax). In Active H® night you will find both, and with the addition of selenium, you will get a trace element that is also important in the elimination of cell-damaging free radicals. Your pineal gland loves these nutrients and rewards you with the production of melatonin.
