So why the fascination, and how can they help you? In the most basic sense, the act of applying colored media to intricate line drawings is a benefit to relaxation and stress reduction. You are able to put the outside world aside for the moment and focus on the art of coloring singularly. Studies have shows that anxiety levels dropped in adults that colored. They did note that simple doodling had no affect on anxiety. The focus on coloring and switching off the brain allows that blocking of anxiety in the moment. Coloring does not have a need for complicated thought processes and like listening to calming music, you are able to get within yourself, isolated from external anxiety, commotion, and distractions.
The lines of your coloring page are the rules you need to share with your team, share with them the boundaries. They are more likely to stay with in the lines if they know that they exist. Next by holding the work up for group and team acceptance they become their own self policing force. They can set self expectations and make constructive self criticism as well. The reward is acceptance and recognition from the team, an old saying is that a person can starve without any feedback, but only needs one good compliment to be filled to overflowing.
Well, apparently they were back then and still are today for people of all ages. People are making the adult coloring books bestsellers on Amazon! At the time of this writing, eight of the top twenty books on the bestsellers list, are coloring books for adults. There must be something behind this recent growth in interest.
