My mother likes to work on puzzles in the winter when she's stuck inside most of the time. A couple of weeks ago my sister ordered the coloring books off tv for me and my mother. My mom hasn't started her yet, but I have colored three pages so far.
I find them so calming and stress relieving. The colors and patterns are so beautiful, and just getting away from the computer screen, phone, and tablet is calming. Once I start a picture, it's hard to put my pencils down.
I can understand why many of the titles for these are so positive and relaxing. Some of the words I've seen in the titles of these types of coloring books have included calm, zen, meditation, relaxation, balance, and stress less.
Plus, I have read that these are a great for your brain power, which is the original reason my sister got one for my mom.
You can find them in a printed version, but for those who don't have time or conditions to color on a paper, they can do it on a phone or a tablet. I use this one - https://itunes.apple.com/us/app/breezy-coloring-book-free/id1163767683?mt=8
