Modern medicine and science knows a lot about the human body. No matter how knowledgeable someone is, however, nobody would claim that they know everything that can be known about it. One little gland that remains mysterious today is the pineal gland. It is located in the brain under the corpus callosum, right in the middle.

The gland is shaped like a pine cone, which is where it got its name. Experts do know that it is responsible for regulating melatonin, which is an essential hormone for managing the circadian rhythm. This tells the body when to sleep and when to wake up. It also appears to have some impact on the pituitary gland, and especially the menstrual cycle in women.

Beyond that, however, not a lot is known. The Cleveland Clinic says:

“The pineal gland is the least understood gland of the endocrine system, and it was the last part of the endocrine system to be discovered. Researchers and scientists still don’t fully understand the pineal gland and melatonin and their functions, because of this, there are no known ways to keep your pineal gland healthy.”

Humans have been aware of this gland for quite some time, with it first being described in the second century CE by Galen. At the time, it was thought that this gland had something to do with spiritual or psychic energy. That idea has managed to stick around all the way through to today.

In fact, it is not uncommon for conspiracy theorists to talk about the pineal gland and how it is being disrupted by things like 5G signals, the COVID-19 vaccine, electromagnetics, and any number of other things. Not surprisingly, these theories will often offer to sell some type of device that can block out those unwanted things and protect the gland, helping people to become more psychically aware.

Naturally, there have been no studies linking any of these things to the gland at all, much less any type of psychic functioning. There are, however, always doctors and legitimate researchers trying to learn more about this important gland and how it works since it plays such an important role in our sleep, which can affect every aspect of our life.

If you thought that was interesting, you might like to read about a quantum computer simulation that has “reversed time” and physics may never be the same.
