One of the treatments for people who are stressed and having trouble sleeping, according to Rosenthal, is to let them walk through a room-sized maze. One such maze is set up at the Dana-Farber Cancer Institute in Boston.
Unlike the tasrat mazes, however, the human mazes have paths that lead to the other side.
"A labyrinth is a good way to relax," Rosenthal concludes.
