Silence during the history of humanity has been part of the deepest reflections. At the same time, we have filled our houses with so much noise that it is difficult to find silence. This has caused an increase in people who, hearing no noise, feel a great abyss within themselves.

Our ears are literally hyper stimulated on a daily basis. The worst thing is that almost all external auditory stimuli that we receive are quite alarming. The roar of vehicle engines or heavy machinery, hustle and bustle, loud music, etc., basically nothing that inspires tranquility.

Studies on silence

Beyond the impact that these stimuli have on our emotional state , science has also shown that it affects our brain. According to a study carried out in Germany by the Research Center for Regenerative Therapies in Dresden, there are brain processes that can only be carried out in silence.

Until recently it was thought that it was impossible for neurons to regenerate. However, with the development of neurogenesis it has been proven that they were wrong. It is not yet clear what exactly promotes neural and brain regeneration, but there are valuable clues regarding this, and one of them is silence.

German researchers conducted their first experiment with rats. The study consisted of leaving them in complete silence for two hours each day. They then looked at the brain to see if there was any change.

The results were convincing. After undergoing this routine for a period of time, it was observed that in all the rats studied there was an increase in the number of cells in the hippocampus. This is the area of ​​the brain that regulates emotions, memory, and learning.

The experts also discovered that the new cells of the nervous system would progressively integrate into the central nervous system and then specialize in different functions. In conclusion, silence has produced a positive change in the brains of animals.

Silence helps us learn better

The brain never rests, even when we are in a calm state, completely still, or during the hours of sleep, this wonderful organ continues to work, but in a different way. When the body is at rest there are other processes that begin to develop and complement those that take place when we are active.

Basically, what happens is a kind of cleaning. The brain evaluates the information and experiences to which we have been exposed throughout the day. Then it organizes them and incorporates the relevant information and gets rid of what is not important.

This process is done completely unconsciously, but it produces conscious effects. That is why there are times when we find the answers while we sleep, or we begin to see things from a new point of view, after having rested for a few hours.

The most interesting thing about all this is that a similar process also occurs when we are silent. The absence of auditory stimuli has almost the same effect as the rest. Silence, in general terms, leads us to think about ourselves and this purifies the emotions and reaffirms our identity.

The important effects of silence

Silence not only makes us smarter, more creative, and more confident. The silence also has positive effects when you are in a state of distress. Humans are very sensitive to sound. So much so that, many times we wake up surprised when an object falls or by a strange noise.

A study conducted at Cornell University found that children who lived near airports maintained a high level of stress. And, not only that, they also had higher blood pressure, and higher levels of cortisol, the stress hormone.

Fortunately, the opposite can also occur, and is evidenced by a study at the University of Pavia , which verified that just two minutes of complete silence were very enriching. In fact, blood pressure was shown to drop and people were able to feel more alert and calm after this short period of silence.

As noted, silence produces great benefits , both intellectually and emotionally. We can confirm that being silent, at least for short periods during the day, is a determining factor for good brain health. And with that, a decisive element to improve our emotional state , our health and our quality of life.
