What is sleep? organisms have evolved biological rhythm that are neatly adapted to the cycles in their environment (life involves patterns - patterns that cycle) Entrainment: when biological rhythms become synchronized to external cues such as light, temperature, or even a clock. Endogenous rhythms: biological rhythms that are generated by our body independent of external cues such as light difficult to study because it is difficult to remove all external cues from a person"s world.
