You are about to find out what scientists have discovered about silence and what special influence it has on one of the center of your being – the brain.
This is a direct revisit to the dangers of noise pollution in our world and a reminder of the precious effect silence has over our entire being.
With these evidences, you would definitely want to find more opportunities to seek total peace and quiet in a lousy, noise polluted world. Research has linked noise pollution to increased blood pressure, sleep loss, and heart disease. They have highlighted the peculiar power of silence to calm our bodies, turn up the volume on our inner thoughts, and attune our connection to the world.
In 1859 “Unnecessary noise is the most cruel absence of care that can be inflicted on sick or well,” said British nurse and social reformer, Florence Nightingale (1859).
1. Growth of new brain cells
A Duke University regenerative biologist Imke Kirste experimented by exposing groups of laboratory mice to a selection of sounds to find out which one might spark the creation of new brain cells.
Using silence as her control, Kirste discovered that two hours of silence a day produced a new cell creation in the hippocampus, the main part of the brain associated with memory. In reviewing the results, Kirste concluded that silence could have been such a strange departure from the norm that it heightened the mice’s alertness.
“We saw that silence is really helping the new generated cells to differentiate into neurons and integrate into the system,” Kirste said.

2. Silence Activates your brain’s memory
Even when the world around us is completely quiet, our brains are extremely adequate at filling in the silence. Take the example of listening to your favorite song, when it suddenly cuts out halfway through. If you know the song well, you’ll continue to hear it play in your head.
By retrieving the memory of the song’s music and lyrics, your brain is creating an illusion of sound. Researcher explains that this is because your brain’s auditory cortex remains hard at work. Even if your ears are not being stimulated by external sounds, your brain always finds a way to muscle its way into staying active.
3. Silence Encourages self-reflection
Without stimulation and distraction, your brain need not focus and goes into a default mode of sorts. That doesn’t mean it completely turns off. Quite the opposite. Your brain at rest will sort and gather information. This is where the self-reflection comes in.
Auditory stimulation forces your brain to process sound and listen to what’s going on around you. Without that external noise, your brain is forced to listen to what’s going on inside of it.
