‘Analgesic’ power of music

A new meaning develops in the mother’s womb, about 18 weeks of pregnancy, the baby develops: hearing. From then on, sounds come to integrate intrauterine life with the rest of the world. The first song we heard was probably the voice of our mother’s heart.

Sometimes a fixed and reassuring rhythm that can be fast. Then a buzz enters the cardiac choir and brings new notes to the composition. And so the symphony of life is growing until the time to be considered as ‘painful’, birth.

However, it is not rare that the baby secures him after hearing known sounds and drowning the disturbing stimulus of lights, sounds and sounds that have never experienced before.
Our relationship with sounds, Certain music would really have the power to make us anesthesia, assurance and changeTo some extent, our perceptions of pain? Select your adventure play list and learn more.

How can music affect you?

Music is a series of compatible sounds with artistic expression function. Everything that produces sound can be ‘music’, even challenging shower singers produce music.

Our relationship with sounds, Intrauterine has a strong potential to awaken memories.Produce emotions, relaxation and equal discomfort, as a microphone is forgotten near a speaker and produces microphonia.

However, beyond psychological effects, music seems to encourage the production of some hormones such as dopamine, serotonin and endorphins in our body.

For example, when breastfeeding mothers hear the baby crying, a neuronal chain is activated, stimulating milk release by signaling oxytocin production that will cause muscle contraction on the breasts.

HE The power of music in provoking emotions and physical reactions It is also used in cinema. The musical pieces are specially selected for each scene and helps to tone of the desired reactions. Maybe if ‘exorcist’ plays black races on a scene, you won’t get sick or shake with fear.

Based on these perceptions, researchers at the University of McGill have tested their effects on music as a non -pharmacological measure for pain treatment, as well as other institutions.

Rhythm of each other’s music

Pain is quite complex and various causes. The central nervous system can be caused by the harmful stimulus of the pain receptors in our body, which leads to the information that there is something bad, such as the buffer of a small finger in a bank.

When this communication occurs between nociceptors (mechanical pain receptors) and nervous system, this painful stimulus can be simply called nociception.

Total pain is not only a concept caused by the discomfort caused by harmful, social and mental (mental and emotional) stimuli, not only this brain systemization.

And the ability to modulate some of our feelings with music and to promote the release of hormones, researchers are trying to control the potential of music usage.

Canada, a survey conducted by McGill University, tested the perception of pain of 60 participants, some musicians and others against painful stimuli.

The research also analyzed the natural ‘time’ of each individual and nominated this phenomenon as “spontaneous production rate”. Each of them can be increased to test by marrying music time..

According to the researchers, this spontaneous reproduction rate is linked to the circadian cycle that regulates our sleep and alertness via cortisol (day) and melatonin (night).

In order to know what the time of each participant will be, the research group asked them to reproduce their ‘bright shil star’ speed. If you’ve sang songs in corals or between friends in a Karaoke, you may have noticed that some are faster, while others sing at a slower speed, this will have their natural time.

After the individual metric was established, they had heat stimuli in the forearm. While our body exceeds a certain temperature limit, it has thermal nociceptors that will trigger a neurophysiological response associated with pain.

Participants were subjected to this discomfort in four cases: silently (heat stimuli) listened to a song at a rate of 15% higher than natural rhythm; It is set 15% slower than the individual rhythm and each individual’s rhythm.

When the data was exposed to music, the patient’s perception of pain pointed to a decrease, and interestingly, the analgesic power of the music was superior when the sound tested was synchronized to the natural rhythm of the tested individual.

According to the research group, the hypothesis of this effect lies in the ability to “rout” the neuronal path of music that will lead to harmful information to the brain. In a simpler example, it will be distracted along the way to the neuronal activation information, which causes only a part of the information to achieve the target.

The findings of the researchers of McGill University are supported by other studies, but there are some warnings.

The study of Canadian University and some Brazilians says that the self -revealing pain, that is, the person perceives pain and feels pain. This approach did not measure whether brain activations in nociceptors are really exposed to effects and how focused or deviated on harmful stimuli.

Thus, when focusing on music, ‘analgesia’ can be triggered by the participant’s request to ignore the heat stimulus. Just when you ignore that you are burning your mouth and eating something, he says it is good because it is delicious or very hungry between checkers and tears.

Thermal nociceptors, which still refer to temperature, transmit information to the central nervous system in more slow and scattered ways, which can save music enough time to disperse a large hierarchy in our brain.

This would be much more difficult with mechanical nociceptors, faster and more focal points in transmitting the information, so you listen to your favorite music, hitting the small one on the couch will allow you to completely forget/ignore the players on your phone. Or speakers.

Next steps To understand the analgesic power of music and how it can cooperate as a non -pharmacological measure to control it.R is to understand how our brain reacts to harmful stimuli while listening to your favorite music.

Soon, image exams can reveal these findings, so that the mechanism of action can be understood and adaptable to each individual, as a result, samba, pagoda, vanera, rock, a few music style and various people listen to them, so, so, so, so, so Analgesia can be associated with not only the musical time, not only over natural time, but also with individual pleasure.
