Evidently, colouring is extremely calming, a great way to relax and take a break. I am not the only one who seems to enjoys these books. In the past year, the popularity of these books has earned them a spot (or more) in Amazon's top 10 best-seller list. Currently, the list contains four colouring books for adults!
I see colouring as a great way unplug from the screen, relieve some stress and spend a couple of minutes to get some "digital detox".
