13 Ways You Can Make Coloring Books A Part Of Your Adult Life (NSFW)

Note: Some of these coloring books are especially adult. You have been warned.

Coloring is not just for kids. We've established that. The act of coloring "incorporates the areas of the cerebral cortex involved in vision and fine motor skills," psychologist Gloria Martínez Ayala explained to HuffPost. Read: coloring actually exercises your brain, which is not all that surprising. "The relaxation that it provides lowers the activity of the amygdala, a basic part of our brain involved in controlling emotion that is affected by stress," she added. Bonus: it helps you de-stress. So why isn't the whole world coloring?

It's a new year, and you're probably about one week into actively keeping struggling to keep up with those resolutions you made just over 10 days ago. We're here to make those visions of self-improvement seem a little more attainable. Here are 13 ways you can make coloring books a part of your adult life.
