Mindfulness is the practice of being fully in the present and can help people achieve peace of mind. Many people use this simple but effective practice to help treat anxiety, stress and panic attacks. Taking the time to ground oneself in their surroundings helps anchor you in the present and ease worry about the past or the future.
