Sitting in silence for 2 hours a day can stimulate the growth of new brain cells

Spending time in silence, specifically, extended periods of quiet, has been shown to help grow new brain cells, according to a 2013 study conducted by researchers at Duke University School of Medicine.
The study, published in the journal Brain, Structure and Function, found that mice exposed to two hours of silence a day experienced increased cell growth in the hippocampus, an area of the brain associated with learning, memory, and emotion. Unlike other stimuli tested (such as noise or music), silence stimulated the strongest neurogenesis, suggesting that a quiet environment may allow the brain to self-regulate and recover.
Although the research was conducted on animals, scientists believe the findings could be valid for humans as well, supporting the mental benefits of silence and mindfulness. Silence isn't just calming, it can physically affect the way the brain is shaped.
