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.

Silence relieves tension

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.

Seeking silence

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.

Regenerating brain cells

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.

The brain’s default mode network

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.

Silence and our mental resources

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."
