Reading and Vitamin D are two ways to improve your mental health.

So, we’ll give people a reason to go outside by creating books tailored to the outdoors.

During Mental Health Awareness Month (May), Headspace will release a line of limited edition books, in collaboration with popular authors, that have seemingly blank pages. The words on these pages will be written in photochromic ink that will only be revealed when the reader is outside.

Headspace will circulate these books through mini outdoor libraries in popular natural spaces.
