Today we know that its biological mission is the internal secretion of melatonin, a hormone whose amount decreases with age and is related to the regulation of wakefulness and sleep cycles (circadian rhythms) and to the processes of puberty, in addition to being a powerful antioxidant and participant in the apoptosis of cancer cells in the thymus.
It is a photosensitive gland, that is, it responds to the variations of light that occur around us. In this way, it is activated in the dark to secrete melatonin, which induces us to a state of calm and introspection.
It is known to everyone that the circulation of hormones through our body causes a series of specific emotions and sensations. The endorphin substances secreted by the pineal gland help us enter a more intimate state of consciousness caused by the feeling of tranquility that melatonin provides.
This segregation of endorphins allows to diminish and relax the senses, which is reflected in the body through a reduction of glycogen in the blood, inducing us to sleep and leading us to a state of sleepiness. As this is a state in which brain activity is at a minimum, it reduces interference from the external world and concentration on oneself is higher. This, on a practical level, allows us to distance ourselves from problems and observe them with a new perspective, which is why most of us take advantage of it to reflect and review everyday events, sometimes finding answers and solutions that without that calm and concentration we would find. difficult to intuit.
Beyond its photosensitive capacity, the latest scientific studies insist that the pineal gland is also a magnetoreceptor, that is, it is sensitive to magnetic fields and transforms its waves into neurochemical stimuli.
Professor José Luis Bardasano, from the University of Alcalá de Henares, is one of the leading specialists in topics related to bioelectromagnetism. In his presentation "Electromagnetism, pineal gland and public health" he tells us that
In the body there are two communication systems: the chemical-based and the electrical-based. In the first (endocrine system), the information signals (messages) are the hormones that are transmitted through information channels: blood vessels, lymphatic vessels, neural channel, etc. reaching the target organs or effectors. In the second (nervous system) the signals are electromagnetic and have a distribution network with centers and "substations" that sits on the neuronal cells (neurons) reaching the muscles, heart, glands, etc. These two systems have evolved in parallel and they collaborate with each other from their origins in perfect chronobiological harmony (chronobiology is the science that studies rhythms). The rhythms and cycles that occur in these two systems are coordinated by the "pineal gland."
For Professor Bardasano, light is the main life cycle timer or synchronizer, while electromagnetic fields are the additional synchronizer. Studies have led to the conclusion that electromagnetic disturbances, like light, interrupt the process of melatonin secretion. A continuous exposure and the consequent reduction of activity in the pineal gland causes common cases of fatigue, stress, mood disorders, sleep disorders, decreased professional performance, depression and even risks of suffering from cancers such as breast cancer.
According to Bardasano, we not only have to be careful with the alterations caused by artificial electromagnetic fields (antennas, telephony, radars, etc.), but also with the variations in natural magnetic fields, such as those caused by strong solar storms. Thus, the pineal gland would be receptive not only to the waves emanating from the geomagnetic field, but to others as important as the Schumman resonance, micropulsations of cosmic origin and any ELF or low-frequency field in general.
From a spiritual point of view, the esoteric doctrines of the East have referred for millennia to the pineal gland as a third eye capable of making the spiritual reality of the human being conscious, the point of union between the physical world and the higher dimensions of the universe. . Precisely because of that situation of introspection provided by the states of sleepiness or semi-vigil to which we referred, these become highly appropriate to connect with the unconscious world, be it our own memories, collective memory and who knows how many more possibilities than just training would allow us to discover.
The secretion of melatonin is drastically reduced after the age of seven, a period in which another series of changes in brain structure also take place. This fact has led many to be interested in the possible link between such changes and the psychic abilities of many younger children, including the controversial phenomenon of "imaginary friends". Continuing with these issues, Professor Sergio Felipe de Oliveira, a neuroscientist at the University of Sao Paulo, has spent years investigating cases of the extrasensory type and clairvoyance. According to him, the mediumistic capacities would be related to the presence of a greater or lesser quantity of hydroxyapatite crystals in the epiphysis.
Be that as it may, it seems clear that through discipline and continuous practice, the activation of the pineal gland becomes the way to access experiences that make us give another meaning to life and realize that not everything moves under the rules of the material and the logical, but there are other worlds as real or more than the one we feed continuously.
And if we do not want to go so far, it does not seem like little reward to be able to end daily stress, avoid cardiovascular problems and obtain a certain serenity to see things from a more positive perspective, all of which leads us to establish more harmonious relationships with others. and sensitive that greatly improve our quality of life. The use you want to give it depends on each person and how far you want to go in the attempt.
