The most cited definition of mindfulness is that of Jon Kabat-Zinn:
“Mindfulness means paying attention in a particular way;
On purpose,
in the present moment, and
Practicing mindfulness has been found to:
       Reduce stress
       Improve concentration levels
       Foster a kinder image of yourself and others
       Reduce worries and dark thoughts
       Increase self-awareness
You’ll learn to pay attention to what you’re doing, to be aware and think in the present, reducing emotional reactivity. Participants will learn to consciously pay positive attention to their thoughts, emotions, and their body’s messages. Without rejecting, ignoring or fully accepting these indicators, they will acquire an understanding of their inner world, recognize and accept it.
Practicing mindfulness at an early age will help a child’s ability to concentrate and retain information tremendously.
Children will be more aware and notice when they’re distracted or stressed, or when they are unable to sleep because they’re worrying. They’ll be able to recognize and acknowledge when they’re restless, tired, sad or angry. Mindfulness gives them tools to learn how to cope with these thoughts, feelings and sensations. They’ll become more resilient and will have more empathy and compassion for others and themselves. The mindfulness program will give them skills to go through life happier and with more confidence.
