Figure 3.18 Sometimes polyphasic sleeping is referred to as the uberman schedule. This Figure compares polyphasic to biphasic sleep. The circle represents time in the twenty-four-hour day, so the small dark blue sectors in the uberman (polyphasic) schedule are the six thirty-minute naps. On the biphasic image, the large dark blue sector is eight hours of nighttime sleep and the small sector is the twenty-minute afternoon nap.
