Most of us agree that hospitals are inherently stressful and it's pretty bleak to stare at a blank wall or wait for a doctor in a cramped, dark room. Sick or not, we'd prefer a sunny view or a Monet watercolor. Yet in an era of escalating healthcare costs, it's important to justify spending on aesthetics and design.

Can an attractive drawing or photograph reduce pain or anxiety? Do patients with art in their environment heal faster?

More and more hospitals think so. And they're putting big money behind it, transforming what were once cold, sterile spaces into mini-museums and contemporary art destinations, complete with audio guides and video installations.
