"Mindfulness" and our "Immune System"

So today . . . let's continue to talk about how "mindfulness" can affect the body and our "immune system"
Now . . . there are 2 levels to being "mindful" . . .
One being the "awareness" of what's happening in our body and "cells" . . .
And the other being the "awareness" of what's happening in our "4" foot personal space . . . this being your personal surroundings.
And when a person pays more attention to what's happening done the street, at a neighbor's house or in the media with today crazy news . . .
This now becomes a "mind-full" person.
But when a person can pay more attention to what's happening "within" their own body and personal space . . .
They become a "mindful" person that is in "tune" with their health, emotions and spirit . . . and then . . . can better "cope" with life.
And with this . . . "mindfulness" can relax our muscles so we experience less pain. It can also aid the brain in releasing a chemical called "endorphin" that acts like a natural "painkiller" to the body . . . that can now . . . help to ease the pain of "fibromyalgia", migraines and IBS,
Being "mindful" . . . can also help with self-control, objectivity, affect tolerance and improve concentration and mental clarity
It can even help our "immune system" . . .
