Why does meditation work?
Thanks to advances in technology, researchers and healthcare providers can see how meditation
affects your brain. However, to understand some of these changes, it helps to know a little about
brain structure.
In your brain, you have billions of neurons, which are cells that use electrical and chemical signals to
send signals to each other. One neuron connects to thousands of others, which is how your neurons
form networks across different parts of your brain. Those networks form different areas of your
brain, which have different jobs and specialties.
Multiple research studies have found that people who meditate regularly have certain differences in
their brain structure. Those changes usually involve brain tissue that’s denser or certain areas of the
brain that are larger than expected, which is a sign that the neurons there have more connections to
each other and the connections are stronger.
The affected areas of the brain are usually those that manage or control your senses (vision, hearing,
etc.), your ability to think and concentrate, and your ability to process emotions. That means the
brains of people who meditate regularly are healthier and less likely to show age-related loss of
function. They also have a stronger ability to deal with and process negative emotions like fear,
anger and grief.
