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.

5 Best Fish Oil Supplements to Buy For A Healthier Brain

5 Best Fish Oil Supplements to Buy For A Healthier Brain

There are many ways that we can make our brains healthier. We use our brains constantly, but we train them through studying, learning, and recalling, among other things. But the issue with these methods is that they only help support particular parts of the brain. They are specialized activities that require certain parts of the rain to work, but they do not support the brain as a whole. So, if you’re looking for ways to help every part of your brain, the best thing you can consider is getting the best fish oil supplements.

Like with all kinds of supplements, fish oil supplements provide a high dosage of vitamins that help support and improve particular parts of your body.

The Benefits of Fish Oil

Fish oil is one of the most common dietary supplements used by people. Broadly speaking, these supplements are rich in omega-3 fatty acids that are great for your health in many ways. Below are just some of their most important, proven benefits:

  • Studies show that those who eat fish are at a lower risk of experiencing heart problems.[1] Supplements like these are common and provide the same health benefits as eating fish
  • Omega-3 also boosts brain function, reducing various mental conditions like bipolar and schizophrenia.[2]
  • Fish oil supplements can also reduce weight and prevent type-2 diabetes and even some cancers.[3]
  • They can also help improve eyesight as our eyes greatly rely on omega-3 fats.[4]

Why Fish Oil Supplements Help Boost Your Energy

As you can tell from the benefits already, having high omega-3 levels greatly and positively impacts our brains. Not only can it prevent mental disorders, but it also has ways of alleviating mood swings, depression, and fatigue. Research shows that consuming lower amounts of omega-3s can result in more mood swings, fatigue, and depression.[5]

Therefore, having a daily dose of fish oil supplements is a way of keeping yourself energized, especially since fatigue primarily stems from our brain. If your brain is filled with energy and isn’t feeling sluggish, your body will also feel the same way.

How To Pick the Best Fish Oil Supplements

When selecting some of the best fish oil supplements available on the market, we based our decision on the following criteria:

Advertising

  • High in Omega-3 – Every fish oil supplement will have Omega-3 and it’s a vital ingredient, but many brands vary on how much their products contain this fatty acid. We selected the ones that have a high amount.
  • Has multiple vitamins – Even though supplements are designed to have many vitamins, the benefits can be self-contained in certain areas and don’t synergize. The ones we selected provide benefits that help your body in multiple ways.
  • Purity – Supplements can often be grounds to include all kinds of unnecessary ingredients. The ones we picked are packed with only the essential vitamins you need.

5 Best Fish Oil Supplements

Here are the 5 best fish oil supplements we picked that you should definitely try:

1. Infuel Omega 3 Fish Oil

        For those looking for a higher dosage of fish oil, EPA, and DHA, one option is the fish oil supplement from Sports Research.

        4. Natrol Omega 3 Fish Oil Natural Lemon Flavor

          One factor that people might have that we didn’t mention on the list is flavor. While what we offer is quality, sometimes, people can’t handle the flavor of some quality products. So, for those who have a particular taste for vitamins, one option to consider is Natrol’s fish oil supplement. This supplement offers a natural lemon flavor thanks to its natural lemon oil ingredient.

          Beyond that, you can expect a middle-of-the-road amount of EPA, DHA, and fish oil with the company suggesting to take one softgel two times a day with a meal. The only real downside to this particular supplement is that you’re giving up a few details and benefits for better flavor. Unlike the other supplements mentioned, this does contain gelatine from bovine, though it’s kept at a minimum.

          5. Nature’s Bounty Fish Oil

            The final fish oil supplement on this list is the one from Nature’s Bounty. Nature’s Bounty has been committed to people’s health for almost 50 years at this point, and this company is known for making trusted products that are well-researched, backed by science, and made from pure ingredients.

            Bottom Line

            While training your brain via certain brain activities and eating plenty of healthy fatty foods will help, we understand that not everyone can meet their Omega-3 requirements. Some people may also have medical conditions that force them to take extra steps in maintaining a healthy brain. This is where supplements shine as they offer plenty of high dosages for the nutrients that your body needs and provide several other benefits as well.

            If you decide to choose any of the listed fish oil supplements, I assure you that you will get a good quality product to help boost your brainpower.
