It has been touted as a stress reliever. But it is far more than that (although it does relieve stress). Mindfulness is really an awareness your experience. In other words, instead of lost in thought or distracted, you are experiencing the world and you in it.
When you are mindful, you are more engaged with others. You taste the food you are eating. You feel the environment around you.
And you are not as lost in thought. Do remember that your emotional state is a derivative of your thoughts (NOT your experience of your environment).
Stress is really about fear. Fear comes from thoughts. Not the experience, but your thoughts and interpretations of the experience. Reconnecting with the experience disengages the thoughts.
Give it a try. I give 3 simple mindfulness exercises in the podcast below.
