Here is an article on how art's creative process help people heal. There have been a number of groups trying to prove this so that hospital's will put creative programming on the schedule. This article is interesting from a research standpoint.
Julia Strecher was 9 years old when she had her second heart transplant. Her body had rejected the first heart she received with particular vehemence: She went into cardiac arrest six times in two hours. As doctors struggled to revive her, she recalls, she could hear them debating whether to give up.
“I was trapped in my body,” says Ms. Strecher, now 18. “I was trying to tell people I was alive and not to pull the plug.” A few months after she went home with her second new heart, she began having nightmares in which she watched herself suffering cardiac arrest.
But then, she began writing down her thoughts about being helpless. Eventually she turned the details into poems and stories. “It was extremely emotionally healing and freeing,” she said. “It helped me relieve a lot of stress and provided a distraction from pain and depression.” The nightmares went away.
