Rebecca Manzi Two hours of silence a day can activate neurogenesis, or the birth of new brain cells, giving rise to a significant increase in the production of neurons, especially in the hippocampus.

Silence isn’t just the absence of noise — it could be a powerful ally for your brain. A study published in Brain Structure and Function found that spending just two hours a day in silence can spark something remarkable: neurogenesis, the birth of new brain cells.
The research was conducted on lab mice exposed to various sound environments, including classical music (Mozart), white noise, puppy sounds, and finally, complete silence. While all sounds triggered brief bursts of brain activity, only silence led to a significant increase in neuron production after one week — particularly in the hippocampus, a brain region essential for memory, learning, and emotional regulation.
“The brain treats silence as an unexpected event”
Researchers believe that the brain perceives silence as an unusual, novel condition — something rare in a world of constant stimuli. This “novelty” may be exactly what kicks off neuroplasticity, the brain’s ability to adapt, rewire, and improve its function over time.
Why you should listen to silence — on purpose
In today’s world of endless notifications, traffic noise, and digital distractions, these findings highlight how intentional silence might be a simple, natural, and free strategy for boosting mental well-being. No apps, no supplements, no elaborate techniques — just pause, disconnect, and let the quiet do the work.
Other studies suggest that practices like listening to relaxing music, getting some sun, or doing deep breathing exercises can also help lower cortisol, the stress hormone, promoting relaxation and mental balance.
“You don’t need to meditate — just be quiet”
What sets silence apart is that it works even without any guided activity. No need to meditate, visualize, or follow a breathing routine. Simply sitting in silence — every day — may be enough to regenerate your mind and enhance cognitive resilience.
So if you’re searching for a grounded, effective way to support your mental health, start here: turn everything off and make space for silence.
