Featuring 40 beautiful colouring pages that can be completed in 10, 20 or 30 minutes, Mindwaves Calming Colouring Tropical offers a dose of creative calm for even the busiest minds. The pages are designed to be coloured in approximately 10-, 20- and 30- minute instalments. As the brain engages in the focused and repetitive (but oh-so-enjoyable!) activity of colouring, the ‘feel-good’ neurotransmitter dopamine will be released. Bliss!
