Many studies have shown that meditation can be a powerful way to reduce anxiety and raise the body systems that calm us down after exposure to stress. The Washington Post last May reported findings of Sara Lazar, a neuroscientist at Massachusetts General from brain scans that showed that some parts of the brain expanded and others became smaller after sustained meditation.
This is part of a big change in thinking about our brains, which until recently were assumed to be fixed, unchangeable. Now we we have a word for the brain’s ability to change – neuroplasticity – as well as increasing evidence about what kinds of attitudes and activities encourage positive changes.
