How Silence Affects Our Brains in A Good Way, Science Explains

How Silence Affects Our Brains in A Good Way, Science Explains

In a world that’s increasingly busy and loud, silence sells. Like clean water, silence is a resource, and can, in fact, be used as a selling point. Consider, your laptop that runs without a peep, meditation retreats, holiday getaways to remote locations, or those noise canceling headphones. Silence is the glue that binds them together.

Silence Has Been Studied by Accident

Over the years, research has emphasized how silence can calm our bodies, improve our connection with the world and actually increase the “noise” of our inner thoughts, with the majority of the research focusing on noise when coming to these conclusions, not silence.

Yes, most researchers have studied silence by accident. For instance, in a 2006 Study, where the physiological effects of music were studied, Luciano Bernardi said the following in Nautilus:

“We didn’t think about the effects of silence. That was not meant to be studied specifically.”

Nevertheless, what were the effects of silence on our brains in these studies?

Two Minutes of Silence Heightened Arousal

In the aforementioned study, Bernardi observed physiological metrics for two dozen subjects when they listened to six songs. According to Bernardi:

“During almost all sorts of music, there was a physiological change compatible with a condition of arousal.”

But what was even more surprising, was what happened when there were silent pauses – two minutes of silence proved far more relaxing than peaceful music or a longer silence played before the experiment started. One of his main findings – silence is heightened by contrasts – is supported by Neurological research, in a study by Michael Wehr in 2010.

Silence Affects Our Auditory Cortex

The 2010 study by Michael Wehr who was observing the brains of mice during short bursts of sound produced some surprising results. Whilst a burst of sound causes the auditory cortex (that part of the brain responsible for processing sound information), to light up, silence also causes a change. A separate network of neurons in the auditory cortex fire up. Wehr says:

“When a sound suddenly stops, that’s an event just as surely as when a sound starts.”

What though happens the moment the auditory cortex fires up?

How Silence Affects our Auditory Cortex: Cell Development

This question was examined by a Duke University regenerative Biologist, Imke Kirste. In the 2013 study, she was analyzing the effects sound has on the brains of adult mice. Four groups of mice were exposed to different auditory stimuli: music, baby mouse noises, white noise, and silence.

The silence was the control, and as with many previous studies, its effect was considered negligible. Once again though the findings were an eye-opener. All the sounds had a short-term neurological effect, but what about silence?

Two hours of silence per day led to cell development in the hippocampus – the brain area responsible for memory formation and emotions. This baffled Kirste. But after some thought she came to the following conclusion – the absence of noise was so artificial and alarming that it caused hyper-alertness in the mice.

Whilst new cell development isn’t always good for health, in this instance, the cells were becoming functioning neurons (a specialized cell that transmits nerve impulses; also known as a nerve cell). Kirste went on to say:

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

Silence Amplifies Self-Reflection

Not only does silence aid in cell generation, but it also aids in self-reflection. We all have what is known as the “default mode” of brain function – found in the prefrontal cortex (located in the front of the brain and responsible for abstract thinking, thought analysis and regulating thinking).

The default mode is always active, receiving and analyzing information. For example, the ability to detect danger happens automatically in this part of the brain. This default mode is also highly active during self-reflection (understanding ourselves) according to Joseph Moran who published a paper titled “What can the organization of the brain’s default mode network tell us about self-knowledge?”

According to Moran and colleagues, when the brain is in this resting mode, it is able to integrate internal and external information into a conscious workspace. When there is silence, your conscious workspace has greater freedom to process the internal and external information, allowing you to better discover your place in the world. Silence amplifies self-reflection.

And perhaps Noora Vikman, an ethnomusicologist (someone who studies music in a cultural context) and silence consultant for Finland’s marketers sums it up best:

“If you want to know yourself you have to be with yourself, and discuss with yourself, be able to talk with yourself.”

Silence then truly is golden. It changes your brain. It changes your life.

How to Develop Big Picture Thinking And Think More Clearly

How to Develop Big Picture Thinking And Think More Clearly

Your neighbors downstairs are playing loud music. Again. How do they not get tired of partying? And why do they choose songs with such a heavy downbeat that the glass in your cupboard is vibrating every two seconds? What can you do to get some peace that you deserve? What should you?

Human mind tends to go in circles whenever faced with a problem without a clear solution. It becomes easy to forget the big picture and get lost in anger and self-pity, wasting our precious time, energy and enthusiasm.

Would it not be nice if we always remembered to put things in perspective?

Would it not be more efficient to face all kinds of problems, from tiny annoyances to life-changing emergencies, with a calm demeanor, sharp focus and fearless determination to promptly take the most efficient action possible?

Alas, humans are not like that. All too often we let anxiety or greed get the best of us and make a rushed or shortsighted decision that we quickly come to regret. Other times, we spend weeks or months at an impasse, rehashing the exact same arguments, unable to accept the compromise required to move forward with any of the available options.

Buddhists talk about getting lost in the “small self.” In this state of mind, we literally forget the big picture and focus on the small one. We start taking our daily problems too personally and, paradoxically, becomes less capable of solving them in an efficient manner. And this is the opposite of big picture thinking.

Let me share with you a story related to big picture thinking…

In 1812, the French army of Napoleon Bonaparte invaded Russia.[1] After a decisive Battle of Borodino, the capture of Moscow and therefore Napoleon’s victory in the war seemed inevitable.

Unexpectedly, the Russian Commander-in-Chief Mikhail Kutuzov made a highly controversial decision of retreating and allowing the French to capture Moscow. Much of the population had been evacuated taking supplies with them. The city itself was set on fire and large parts of it burned into the ground.

After waiting in vain for Russia to capitulate, Napoleon had to retreat in the middle of a bitterly cold winter. He won the battle but lost the war. The campaign ended in a disaster and the near destruction of the French army.

What can we learn from this historical lesson?

1. Focus on the Consequences

Napoleon focused on the important part: capturing Moscow. Nobody could accuse him of thinking small. Yet he overlooked that the Russian army could still fight even after giving up the country’s most important city.

So was Moscow not an important target after all?

Success expert Brian Tracy has a litmus test: things are important to the extent that they have important consequences. Things are unimportant to the extent that they have no important consequences.[2]

When faced with a choice, ask yourself, what would be the consequences of each option?

  • Want to spend an hour studying or watching the new series on Netflix? What would be the consequences of each option? Netflix can sometimes be a better choice, but it helps to put things in perspective.
  • Want to maintain your apartment by yourself or to pay a cleaning service? Would would be the consequences of each option?
  • Want to meet up for coffee with this acquaintance of yours or catch up on your work instead? What would be the consequences of each option?

The choice can be different for different people. An aspiring filmmaker may have a legitimate reason for choosing Netflix. Personally, cleaning your own apartment can be relaxing and nourishing even if the economics of hiring a cleaner looks compelling because you are earning a high hourly rate.

This is where you will need a basic idea of who you are — what are your goals, values and aspirations.

2. Flip Defeat Into Victory

Kutuzov managed to turn Russia’s defeat into a historic victory by recasting the problem in a wider context: losing Moscow need not mean losing the war.

Despite the symbolic meaning attached to the Kremlin, the churches, the priceless treasures that had been stored in the city for centuries, the outcome of the campaign was ultimately determined by the strength of the remaining armies.

If you can adopt this result-oriented perspective, many of your personal defeats may be flipped into victories as well. Few events in a human life are absolutely good or absolutely bad, and it usually takes many years to recognize in retrospect, what role a particular encounter did play in your story.

Therefore we have every reason to look for the good in the things that happen to us.

This is a very practical attitude, far from baseless “positive thinking.” After all, if something unfortunate has happened to you and you find good sides in this circumstance, you will then be better positioned to take advantage of those good sides.

Say your noisy neighbors are affecting your productivity. What if it is a blessing in disguise? How can you turn this defeat into a victory?

  • Perhaps you are too serious about life and could learn how to have more fun. Join your neighbors or go out for a walk instead of working;
  • Perhaps you only wanted to be productive while instead procrastinated on social media. Now that your procrastination has been interrupted, stop and acknowledge this much greater obstacle to your productivity;
  • Perhaps you are too sensitive to interference. Take this opportunity to practice ignoring the noise and doing your best anyway;
  • Perhaps you have a victim mentality and the feeling of unfairness drains you more than any actual nuisance your neighbors might have caused. Try accepting this lapse in your productivity the way you would accept bad weather.

Get used to finding opportunities in your problems. This is the quintessential big picture thinking.

3. Ask for Advice

Both Napoleon and Kutuzov had trusted advisers to discuss their affairs with. In general, getting a different perspective — or several — can only help inform your understanding and lead to better decisions. Just ensure that the people giving you advice are competent in the particular area where experience is needed.

Paying money for advice can also be a wise investment. Lawyers, tax accountants, medical doctors spend years learning how to assist people like yourself in living more successful, more fulfilling lives.

A quick legal consultation can save you a fortune down the line or even keep you out of big trouble. A medical check-up can uncover potential issues and help keep you healthy and active for years to come.

Even big, complex dilemmas at your job or in your romantic relationship can be tackled more effectively by partnering up with a coach or a therapist or, of course, with the help of a wise friend.

4. Beware of Biased Advice

Many imperfect decisions occur in response to an imperfect piece of advice that you choose to act on. This advice often comes from a biased party.

For example, we are often encouraged to buy something that we supposedly need:

  • Protect your skin from harmful UV rays by using a special lotion.
  • Fortify your health by taking multivitamins.
  • Connect with your friends by sending them elaborate gifts.
  • Brighten your weekend by consuming a delicious pastry.
  • Become more productive by getting a faster computer.

However, most purchases are unnecessary.

Some, such as the sunscreen, do have legitimate benefits when used properly.[3] Others, such as multivitamins, only make a difference for a small group of people.[4]

Advertisers of those benefits inevitably want to narrow your focus in order to overstate the importance of their product. They frequently present it as the only solution to your problem, whether real or imaginary.

After all,

  • Skin can also be protected from the sun by wearing appropriate clothing.
  • Health can be better fortified by consuming a balanced diet and getting regular exercise.
  • Spending time or talking on the phone with your friends is the foremost way of connecting with them, and it is virtually free.
  • Your weekend can be brightened by doing something that you love.
  • You can become more productive by focusing on the tasks that have the most important consequences. A faster computer can, in fact, decrease productivity by making it easier to multitask and by enabling your favorite distractions.

There are other sources of imperfect advice. Politicians also frequently want us to focus on a particular “big picture,” to the exclusion of the alternatives.

Even loving parents can be guilty of the same. They can advise their children to pick a career path that is safe and respectable, based on their “big picture” that in life one has to make a living. A child may disagree, however, based on another “big picture” that one’s life has to have meaning and fulfillment.

Bottom Line

It is human nature to make rushed, emotional decisions based on incomplete information, then regret those decisions later on.

You can protect yourself from poor judgment by striving to attain the big picture when careful consideration is called for.

Focus on the consequences of your decision before considering how you feel about it.

Play with the cards you’ve been dealt, but look for opportunities in each situation and you will find them.

Ask knowledgeable mentors for advice, but beware of biased people who have an opinion, but do not necessarily have your best interest in mind.

Yet remember, true big picture thinking comes from hard-won experience. Legendary military commanders Napoleon Bonaparte and Mikhail Kutuzov were both injured on the battlefield.

Clear thinking comes from putting your big picture to the test of reality.
