Turns out silence is fantastic for developing brains. So go ahead and pat yourselves on the back if you insist children sit in silence for a couple of hours a day. *Sips lemon juice*
A 2013 study on mice published in the journal Brain, Structure and Function used differed types of noise and silence and monitored the effect the sound and silence had on the brains of the mice. The silence was intended to be the control in the study but what they found was surprising. The scientists discovered that when the mice were exposed to two hours of silence per day they developed new cells in the hippocampus. The hippocampus is a region of the brain associated with memory, emotion and learning.
The growth of new cells in the brain does not necessarily translate to tangible health benefits. However, in this instance, researcher Imke Kirste says that the cells appeared to become functioning neurons.
“We saw that silence is really helping the new generated cells to differentiate into neurons, and integrate into the system.”
In this sense silence can quite literally grow your brain.
