Science Says Silence Is Much More Important To Our Brains Than We Think

Science Says Silence Is Much More Important To Our Brains Than We Think

In 2011, the Finnish Tourist Board ran a campaign that used silence as a marketing ‘product’. They sought to entice people to visit Finland and experience the beauty of this silent land. They released a series of photographs of single figures in the nature and used the slogan “Silence, Please”. A tag line was added by Simon Anholt, an international country branding consultant, “No talking, but action.”

Eva Kiviranta the manager of the social media for VisitFinland.com said: “We decided, instead of saying that it’s really empty and really quiet and nobody is talking about anything here, let’s embrace it and make it a good thing”.

Finland may be on to something very big. You could be seeing the very beginnings of using silence as a selling point as silence may be becoming more and more attractive. As the world around becomes increasingly loud and cluttered you may find yourself seeking out the reprieve that silent places and silence have to offer. This may be a wise move as studies are showing that silence is much more important to your brains than you might think.

Regenerated brain cells may be just a matter of silence.

     A 2013 study on mice published in the journal Brain, Structure and Function used differed types of noise and silence and monitored the effect the sound and silence had on the brains of the mice. The silence was intended to be the control in the study but what they found was surprising. The scientists discovered that when the mice were exposed to two hours of silence per day they developed new cells in the hippocampus. The hippocampus is a region of the brain associated with memory, emotion and learning.

    The growth of new cells in the brain does not necessarily translate to tangible health benefits. However, in this instance, researcher Imke Kirste says that the cells appeared to become functioning neurons.

    “We saw that silence is really helping the new generated cells to differentiate into neurons, and integrate into the system.”

    In this sense silence can quite literally grow your brain.

    The brain is actively internalizing and evaluating information during silence

      A 2001 study defined a “default mode” of brain function that showed that even when the brain was “resting” it was perpetually active internalizing and evaluating information.

      Follow-up research found that the default mode is also used during the process of self-reflection. In 2013, in Frontiers in Human Neuroscience, Joseph Moran et al. wrote, the brain’s default mode network “is observed most closely during the psychological task of reflecting on one’s personalities and characteristics (self-reflection), rather than during self-recognition, thinking of the self-concept, or thinking about self-esteem, for example.”

      When the brain rests it is able to integrate internal and external information into “a conscious workspace,” said Moran and colleagues.

      When you are not distracted by noise or goal-orientated tasks, there appears to be a quiet time that allows your conscious workspace to process things. During these periods of silence, your brain has the freedom it needs to discover its place in your internal and external world.

      The default mode helps you think about profound things in an imaginative way.

      As Herman Melville once wrote, “All profound things and emotions of things are preceded and attended by silence.”

      Silence relieves stress and tension.

        It has been found that noise can have a pronounced physical effect on our brains resulting in elevated levels of stress hormones. The sound waves reach the brain as electrical signals via the ear. The body reacts to these signals even if it is sleeping. It is thought that the amygdalae (located in the temporal lobes of the brain) which is associated with memory formation and emotion is activated and this causes a release of stress hormones. If you live in a consistently noisy environment that you are likely to experience chronically elevated levels of stress hormones.

        A study that was published in 2002 in Psychological Science (Vol. 13, No. 9) examined the effects that the relocation of Munich’s airport had on children’s health and cognition. Gary W. Evans, a professor of human ecology at Cornell University notes that children who are exposed to noise develop a stress response that causes them to ignore the noise. What is of interest is that these children not only ignored harmful stimuli they also ignored stimuli that they should be paying attention to such as speech. 

        “This study is among the strongest, probably the most definitive proof that noise – even at levels that do not produce any hearing damage – causes stress and is harmful to humans,” Evans says.

        Silence seems to have the opposite effect of the brain to noise. While noise may cause stress and tension silence releases tension in the brain and body. A study published in the journal Heart discovered that two minutes of silence can prove to be even more relaxing than listening to “relaxing” music. They based these findings of changes they noticed in blood pressure and blood circulation in the brain.

        Silence replenishes our cognitive resources.

          The effect that noise pollution can have on cognitive task performance has been extensively studied. It has been found that noise harms task performance at work and school. It can also be the cause of decreased motivation and an increase in error making.  The cognitive functions most strongly affected by noise are reading attention, memory and problem solving.

          Studies have also concluded that children exposed to households or classrooms near airplane flight paths, railways or highways have lower reading scores and are slower in their development of cognitive and language skills.

          But it is not all bad news. It is possible for the brain to restore its finite cognitive resources. According to the attention restoration theory when you are in an environment with lower levels of sensory input the brain can ‘recover’ some of its cognitive abilities. In silence the brain is able to let down its sensory guard and restore some of what has been ‘lost’ through excess noise. 

          Summation

          Traveling to Finland may just well be on your list of things to do. There you may find the silence you need to help your brain. Or, if Finland is a bit out of reach for now, you could simply take a quiet walk in a peaceful place in your neighborhood. This might prove to do you and your brain a world of good.

          Science Says Screaming Is Good For You

          Science Says Screaming Is Good For You

          There are many reasons why people might scream – they’re angry, scared, or in pain (or maybe they’re in a metal band!). Some might say that screaming is bad, but here’s why science says it’s good for you.

          “For the first time in the history of psychology there is a way to access feelings, hidden away, in a safe way and thus to reduce human suffering. It is, in essence, the first science of psychotherapy.” — Dr. Arthur Janov

          Primal Therapy

          Dr. Arthur Janov invented Primal Therapy in the late 1960’s. It is a practice that allows the patient to face their repressed emotions from past trauma head on and let those emotions go. This treatment is intended to cure any mental illness the patient may have that surfaced from this past trauma. In most cases, Primal Therapy has lead Dr. Janov’s patients to scream towards the end of their session, though it was not part of the original procedure. During a group therapy session that was at a standstill, Dr. Janov says that one of his patients, a student he called Danny, told a story that inspired him to implement a technique that he never would have thought of on his own.

          How it Started

          “During a lull in our group therapy session, he told us a story about a man named Ortiz who was currently doing an act on the London stage in which he paraded around in diapers drinking bottles of milk. Throughout his number, Ortiz is shouting, ‘Mommy! Daddy! Mommy! Daddy!’ at the top of his lungs. At the end of his act he vomits. Plastic bags are passed out, and the audience is requested to follow suit.”

          It doesn’t end there, though. Dr. Janov said that his patient was quite fascinated with that story, and that alone moved him to suggest something even he believed to be a little elementary.

          “I asked him to call out, ‘Mommy! Daddy!’ Danny refused, saying that he couldn’t see the sense in such a childish act, and frankly, neither could I. But I persisted, and finally, he gave in. As he began, he became noticeably upset. Suddenly he was writhing on the floor in agony. His breathing was rapid, spasmodic. ‘Mommy! Daddy!’ came out of his mouth almost involuntarily in loud screeches. He appeared to be in a coma or hypnotic state. The writhing gave way to small convulsions, and finally, he released a piercing, deathlike scream that rattled the walls of my office. The entire episode lasted only a few minutes, and neither Danny nor I had any idea what had happened. All he could say afterward was: ‘I made it! I don’t know what, but I can feel.’”

          Delving deeper

          Dr. Janov says he was baffled for months, but then he decided to experiment with another patient with the same method, which lead to a similar result as before. The patient started out calling “Mommy! Daddy!” then experienced convulsions, heavy breathing, and then eventually screamed. After the session, Dr. Janov says his patient was transformed and became “virtually another human being. He became alert… he seemed to understand himself.”

          Although the initial intention of this particular practice wasn’t to get the patient to scream, more than once did his Primal Therapy sessions end with the patient screaming and feeling lighter, revived, and relieved of stresses that were holding them down in life.

          Some Methods To Practice Screaming

          If you want to try it out for yourself, keep reading!

          • Step 1: Be Alone — Be alone. If you live in a place that you can’t be alone, it might be a good idea to talk to your family or roommates and explain to them what you’re about to do and make sure they’re okay with it. If you’re good to go, move on to step 2.
          • Step 2: Lie Down — Lie down on a yoga mat on your back and place a pillow underneath your head. If you don’t own a yoga mat, you can use a rug or even a soft blanket.
          • Step 3: Think — Think of things that have hurt you or made you angry. It can be anything from your childhood or even something that happened recently to make yourself cry, if you’re not already crying or upset. You could even scream “Mommy! Daddy!” just like Dr. Janov’s patients did to get yourself started.
          • Step 4: Scream — Don’t hold anything back; cry and scream as loud as you can. You can also pound your fists on the ground, or just lie there and scream at the top of your lungs.

          After this, you should return your breathing to a normal and steady pace. You should feel lighter, like a weight has been lifted off of you. If not, you can also try these other methods.

          Scream Sing

          Scream singing” is referring to what a lot of lead singers in metal or screamo bands will do. I’ve tried it and although I wasn’t very good at it, it was fun and definitely relieved me of any stress I was feeling from before. It usually ends up sounding like a really loud grunt, but nonetheless, it’s considered screaming.

          • Step 1 — Bear down and make a grunting sound.
          • Step 2 — Hiss like a snake and make sure to do this from your diaphragm (your stomach) for as long as you can.
          • Step 3 — Breathe and push your stomach out for more air when you are belting notes, kind of like you would if you were singing.
          • Step 4 — Try different ways to let out air to control how long the note will last, just make sure not to let out too much air.
          • Step 5 — Distort your voice by pushing air out from your throat, just be careful not to strain yourself.
          • Step 6 — Play around with the pitch of your screams and how wide your mouth is open – the wider your mouth is open, the higher the screams will sound. The narrower or rounder your mouth is (and most likely shaped like an “o”), the lower the screams will sound.
          • Step 7 — Start screaming to metal music. If you’re not a huge metal fan, it’s okay. You don’t have to use this method if you don’t want to.

          If you want a more thorough walkthrough of how to scream sing, here’s a good video tutorial. If this method is too strenuous on your vocal chords, stop. Also, make sure to stay hydrated when scream singing and drink lots of water.

          Scream into a pillow

          Grab a pillow and scream into it. This method is probably the fastest and easiest way to practice screaming. Just make sure to come up for air.

          Always remember to make sure that you’re not going to disturb anyone while practicing any of these methods of screaming. And with that, happy screaming!
