Noise pollution may 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.
Silence has the opposite effect, releasing tension in the brain and body.
The constant 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.
When we can finally get away from these sonic disruptions, our brains’ attention centers have the opportunity to restore themselves.
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.
Silence can quite literally grow the brain.
Research 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.
Silence helps activate our brain to work better and jog its memory banks efficiently.
The former may seem worse, but both can be detrimental to our productivity—and sanity.
