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.[1] 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,[2]

“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.[3]

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.[4]

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.[5]

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.

Are You Right-Brain Dominant? (7 Right Brain Characteristics)

Are You Right-Brain Dominant? (7 Right Brain Characteristics)
Advertising

Do you prefer drawing to writing? If so, you are most likely right-brain dominant.

When we break down the characteristics of a right-brain dominant person, we can think of someone very visual, a little spontaneous, and often labeled as emotional. They may struggle with memorization, as well as paying attention to detail. We most likely label those who are right-brain dominant as “creative”. Their learning styles often differ from a left-brain dominant person, who traditionally tends to do very well in western school systems. A right-brain dominant person on the other hand, can find it difficult to settle into routines. However, working in group settings are ideal for them, this helps them nurture the creative nature that comes with being right-brain dominant.

Here’re 7 right brain characteristics:

1. You Prefer Drawing to Writing

If you are right-brain dominant, you most likely would rather create a picture to tell your story than writing it down word for word. Right-brain dominant people often find themselves creating visuals for ongoing learning methods.

2. You Prefer Open-Ended Questions to Multiple Choice

Since right-brain dominant people thrive in group settings, answering questions posed in an open-ended format tends to be more natural for them than answering questions in multiple choice format. Settings that allows for discussion and freedom when finding solutions is better for a right brain dominant person than finding solutions through “black and white” methods.

3. You Tend To Be Disorganized

A right-brain dominant person may have difficulties staying on task and keeping things in order. This can be as simple as maintaining a neat and clean work desk or completing specific academic tasks.

4. You Have Difficulty Focusing for Long Periods of Time

A right-brain dominant person requires constant stimulation. Remember, they are visual beings. If you place a right-brain dominant person in a traditional western school, they will have a hard time focusing, as they need constant stimulation.

5. You Have Less Than Average Memorization Skills

When it comes to memorization, right-brain dominant people require a unique way to call upon information they’ve digested.[1] Instead of repetition to remember specific details, use meanings, colors, visual representations and emotions.

6. You Are a Holistic Thinker

A right-brain dominant person refers to the bigger picture, in other words they are holistic thinkers. They have the ability to recognize interconnectedness of the smaller pieces that make up the big picture.

7. You Can Be Spontaneous And Intuitive

Right-brain dominant people like adventure and thrive off of energy and spontaneity. They are emotionally intuitive and tend to be emotional by nature.

How to Make Good Use of Right Brain Characteristics?

If you have right-brain tendencies, you know that some of the characteristics listed above can be used to your advantage. You can choose a career that corresponds to these strengths in order to nurture your creative self.

Don’t be afraid to go into the opposite direction as well– having some right-brain traits doesn’t stop you from pursuing left-brain activities, and strengthening your own weaknesses.

Final Thoughts

Be sure to be mindful that the labels “left” or “right-brain” are not truly an important matter. It just helps you observe the characteristics you already have.

Don’t pigeonhole yourself by solely identifying with one or the other, because in reality both hemispheres are functioning. Determining if you fit the left or right-brained stereotype will merely help you identify your strengths and weaknesses, and help you expand on them later.
