Comic artistry to relieve stress

Here's an odd story from the Lancashire Telegraph in Britain about an artists' class being held for the purpose relieving stress:

AN international comic book artist is to draw on his experience to offer staff stress-busting sessions.

Blackburn-based Tim Perkins is holding the unusual scheme, which will let employees design a comic book or storyboard in a bid to help them relax.

I don't know, is such a thing possible, that it can help people to relax?
