1. The single most important fact to remember is that the time when sleep occurs is more important than the duration of the sleep period. You can't fight circadian rhythms! We all have internal clocks that are genetically controlled. These clocks create an internal timing mechanism for sleep. These clocks evolved from dark (night)/light (day) cues. This signal is very primitive because it is based on the rotation of the earth on its axis. Sleeping in synch with circadian rhythms is more restorative, of better quality, than sleeping out of synch with circadian rhythms. Jet-lag syndrome is an example of sleep not in synch with circadian rhythms.

Additionally, a bout of sleep that is continuous (consolidated) is much more restorative than a bout of sleep that in interrupted (fragmented).
