The Importance Of Silence To The Brain


In a noisy and distracting world, finding silence can benefit your body and brain.

We live in a noisy and distracting world where silence is increasingly hard to find and that can negatively affect our health.

In 2011 The World Health Organization report called noise pollution a "modern epidemic", concluding that "Strong evidence shows that environmental noise exposure has adversely affected people's health."

We continually fill our ears with music, TV and radio news, audio files and of course, the endless sounds we make in our heads.
Think about it: How many silent moments do you spend every day? The answer is probably very few.

As our internal and external environments become more and more noisy, many people are beginning to seek silence, whether through the practice of sitting silently for 10 minutes every morning or heading to a hidden place. Quiet silence for 10 days.

Want inspiration to find some peace and quiet? Here are four scientific ways to support that silence is good for your brain - and spending time with it can make you feel less stressed, more focused and more creative.

1. Silence relieves stress and stress

Florence Nightingale, a 19th-century British nurse and activist, once wrote that "Unnecessary noise is the cruelest lack of health care that can cause illness." Night gale suggests that excessive, useless sounds can cause anxiety, insomnia, and panic in recovering patients.

It turned out that noise pollution was once found to lead to high blood pressure and heart attacks, as well as impairing hearing and general health. Noisy sounds increase the level of stress caused by the activation of the brain's amygdala and the release of the stress hormone cortisol, according to the study.

An unpublished article in 2014 by environmental psychologist Dr Craig Zimring said high levels of noise in the neonatal intensive care unit increased blood pressure, increased heart rate and disrupted sleep.

While being too noisy can cause stress and stress, the study found that silence has the opposite effect, releasing stress in the body and brain.

Study shows that two minutes of silence was more relaxing than listening to "relaxing" music, based on changes in blood pressure and blood circulation in the brain.

2. Silence helps replenish spiritual resources

In our daily lives, the senses are absorbing a lot of stimulation from all sides. When we can get rid of distracting sounds, the brain's attention center has a chance to recover.

The constant need for concentration in modern life places a heavy burden on the prefrontal cortex, which is the place for highly focused thinking, decision making and problem solving.

As a result, the resources devoted to our focus become exhausted. We will be distracted and mentally tired, and may struggle to concentrate, solve problems and come up with new ideas.

But the theory of attention recovery, the brain can restore its limited cognitive resources when we live in environments that have less impact on the senses. In silence - for example, the tranquility you find when walking alone in nature - the brain can lower its sensory protection levels.

3. In silence, we can touch the brain's default mode network.

The brain's default mode network is activated when we engage in what scientists call "self-created awareness," such as daydreaming, meditation, imagining the future or just letting our mind wanders.

When the brain is idle and disconnected from external stimulation, we can touch our inner stream of thoughts, emotions, memories and ideas. Joining this network helps us to contemplate many things from our experience, empathize with others, be more creative and reflect on our emotional and mental state.

To do this, we need to get rid of the distractions that make us linger on the superficial surface of the mind. Silence is a way to get there.

The default mode operation helps us to think deeply and be creative. 
Herman Melville once wrote that:
 "All the profound and emotional things are led and there is the participation of silence in it."

4. Quietness can regenerate brain cells.

Silence can literally make the brain grow.
The 2013 mouse study, published in the journal Brain, Structure, and Function, includes comparing the effects of environmental noise, white noise, puppy calls and silence on the brain. Although the researchers indicated using silence as a way of calming between study trials, they found that two hours of silence each day led to the development of new cells during the Walrus, an important brain area associated with learning, memory and emotions.

Preliminary findings also suggest that tranquility can be combined to treat conditions such as depression and Alzheimer's disease, which are linked to reduced rates of neuron regeneration in the Hill region.
