Silence is Good For the Brain
As many of you may know, Kechara Forest Retreat regularly organizes Inner Peace Retreats. I came across the article ‘Why Silence is So Good for Your Brain‘ and I wanted to share it so that those who are planning to attend these retreats in KFR can harness the full benefits of the program.
As people begin to realize the increasing importance of meditation and looking within, more places are offering meditation courses, and scientists are conducting studies on the effects of meditation. While some may claim that meditation is a phenomenal discovery, in reality meditation has always been a tool used by various yogis in the past and also Buddhists.
As a Buddhist, reading about these scientific discoveries does not excite me at all, simply because I already know the effectiveness of meditation. I have seen how my holy teachers have used meditational methods and gained much attainments from it. However, I do understand that others may not have this type of exposure and as such, scientific studies offer us the opportunity to appreciate the effectiveness of meditation.
As a Buddhist teacher, I would very much like my students to understand that meditation is not a means to an end as some modern adaptations have made it out to be… but it is in actuality a tool to further our spiritual practices. Meditation programs are often marketed as a form of stress relief or to help us deal with depression, etc. While these are genuine, beneficial side effects of meditation, they are however not the goal of a Buddhist practitioner. As we progress on the Buddhist path, our meditations should be more focused on our actual goal — Enlightenment — instead of these temporary benefits.
Therefore, meditation is a technique that we should integrate into our lives. What is the point if we only feel at peace while engaging in short retreats in KFR, but revert back to our anxious and stressed mental states at work? In this case, we have not applied what we have learned as it did not help us in our day to day life. So, we should always make it a point to practice meditation whenever we can.
Some may think that it is impossible, but in fact we are meditating at every moment. The only difference is that the object we are meditating on doesn’t contribute to our inner peace! For example, we may be thinking deeply about our anger towards someone, that’s a form of meditation; we may be wondering if our children are doing well at school, that too is a form of meditation. So, do not think for a moment that you are unable to accomplish this… after all, what you meditate on is based on what you are habituated to, so start changing your focus today.
I hope this short sharing will help you to be more focused when engaging in any form of meditation and meditational retreats. I wish everyone the best and may you continue to apply what you learn in your lives continuously.
Why Silence is So Good For Your Brain
by Carolyn Gregoire, syndicated from huffingtonpost.com, Mar 14, 2016
We live in a loud and distracting world, where silence is increasingly difficult to come by — and that may be negatively affecting our health.
In fact, a 2011 World Health Organization report called noise pollution a “modern plague,” concluding that “there is overwhelming evidence that exposure to environmental noise has adverse effects on the health of the population.”
We’re constantly filling our ears with music, TV and radio news, podcasts and, of course, the multitude of sounds that we create nonstop in our own heads. Think about it: How many moments each day do you spend in total silence? The answer is probably very few.
As our internal and external environments become louder and louder, more people are beginning to seek out silence, whether through a practice of sitting quietly for 10 minutes every morning or heading off to a 10-day silent retreat.
Inspired to go find some peace and quiet? Here are four science-backed ways that silence is good for your brain — and how making time for it can make you feel less stressed, more focused and more creative.
1. Silence relieves stress and tension
Florence Nightingale, the 19th century British nurse and social activist, once wrote that “Unnecessary noise is the most cruel absence of care that can be inflicted on sick or well.” Nightingale argued that needless sounds could cause distress, sleep loss and alarm for recovering patients.
It turns out that noise pollution has been found to lead to high blood pressure and heart attacks, as well as impairing hearing and overall health. Loud noises raise stress levels by activating the brain’s amygdala and causing the release of the stress hormone cortisol, according to research.
An unpublished 2004 paper by environmental psychologist Dr. Craig Zimring suggests that higher noise levels in neonatal intensive care units led to elevated blood pressure, increased heart rates and disrupted patient sleep patterns.
Just as too much noise can cause stress and tension, research has found that silence has the opposite effect, releasing tension in the brain and body.
A 2006 study published in the journal Heart found two minutes of silence to be more relaxing than listening to “relaxing” music, based on changes in blood pressure and blood circulation in the brain.
2. Silence replenishes our mental resources
In our everyday lives, sensory input is being thrown at us from every angle. When we can finally get away from these sonic disruptions, our brains’ attention centers have the opportunity to restore themselves.
The ceaseless attentional demands of modern life put a significant burden on the prefrontal cortex of the brain, which is involved in high-order thinking, decision-making and problem-solving.
As a result, our attentional resources become drained. When those attention resources are depleted, we become distracted and mentally fatigued, and may struggle to focus, solve problems and come up with new ideas.
But according to attention restoration theory, the brain can restore its finite cognitive resources when we’re in environments with lower levels of sensory input than usual. In silence — for instance, the quiet stillness you find when walking alone in nature — the brain can let down its sensory guard, so to speak.
3. In silence, we can tap into the brain’s default mode network
The default mode network of the brain is activated when we engage in what scientists refer to as “self-generated cognition,” such as daydreaming, meditating, fantasizing about the future or just letting our minds wander.
When the brain is idle and disengaged from external stimuli, we can finally tap into our inner stream of thoughts, emotions, memories and ideas. Engaging this network helps us to make meaning out of our experiences, empathize with others, be more creative and reflect on our own mental and emotional states.
In order to do this, it’s necessary to break away from the distractions that keep us lingering on the shallow surfaces of the mind. Silence is one way of getting there.
Default mode activity helps us think deeply and creatively. As Herman Melville once wrote, “All profound things and emotions of things are preceded and attended by silence.”
4. Getting quiet can regenerate brain cells
Silence can quite literally grow the brain.
A 2013 study on mice, published in the journal Brain, Structure, and Function, involved comparing the effects of ambient noise, white noise, pup calls and silence on the rodents’ brains. Although the researchers intended to use silence as a control in the study, they found that two hours of silence daily led to the development of new cells in the hippocampus, a key brain region associated with learning, memory and emotion.
While preliminary, the findings suggested that silence could be therapeutic for conditions like depression and Alzheimer’s, which are associated with decreased rates of neuron regeneration in the hippocampus.
