Any creative activity that lets you break away from your daily chores can give you relief from anxiety. This includes colouring as well. But you will also get the same effect if you take up drawing or painting. However, the advantage of colouring is that you don’t need any special training to take it up as a hobby. Also, it is really easy to learn. There are colour books of varying difficulty, and you can choose one that matches your skill level. As you colour more complex pictures and patterns, it will require more of your concentration and will help you take your mind off your anxieties.
