Axia College Material Appendix C The Sleep Matrix Why do we sleep? What governs when or how long we sleep?

Unformatted text preview: behavioral disturbances. X We have a sleep-wake cycle. X When we sleep is based on some evolutionary aspects. x What are the main differences between the recuperation and circadian theories? Recuperation theory : Being awake disrupts the homeostasis of the body in some way and that some sleep is required to restore it. Circadian theory : Sleep is not a response to internal imbalance. A neural mechanism has evolved to encourage animals to sleep in those times of day when they do not usually engage in activities necessary for their survival. Which theory do you most agree with? Explain . The circadian theory sounds more plausible to me because it that suggest that daily sleep time of a specific species is related to how vulnerable it is while it is asleep as well as how much time it requires each day to feed itself and to take care of its survival needs.
