Coloring books for adults have become the latest trend, and, unlike some fads, this one is actually really good for you. According to clinical psychologist Ben Michaelis, coloring is a stress-free activity that relaxes the amygdala — the fear center of the brain — and allows your mind to get the rest it needs. But coloring has other indirect health benefits as well. Even if it didn’t make us healthier, many of us would still probably be coloring as adults. It’s true, of course, that the inherent fun of coloring might be linked to its de-stressing properties, but I think the activity’s helpful qualities are really just an added bonus. At the end of the day, coloring is good for you because it’s fundamentally fun.
