The Sleep Matrix Why do we sleep? What governs when or how long we sleep? This activity will assist you in understanding two common sleep theories, recuperation and circadian, which provide different answers to these questions. Depending on which one you support, it may change your outlook on sleep and your current sleeping habits.
Categorize each characteristic under the correct theory—recuperation or circadian—by placing an “X” in the appropriate column. Then, answer the questions that follow.
Recuperation Circadian Sleep restores the body to a state of homeostasis. X
Sleep plays no role in physiological functioning.
X We become tired when it is dark out.
X Function of sleep is to restore energy levels X
Function of sleep is to conserve energy X
We become tired from wakefulness.
X We sleep until the body is physiologically sound. X
We sleep based on an internal timing mechanism.
X Sleep depends on vulnerability from predators.
X Sleep deprivation may cause behavioral disturbances. X
We have a sleep-wake cycle.
X When we sleep is based on some evolutionary aspects. X
1. What are the main differences between the recuperation and circadian theories? Some of these differences are as follows with recuperation you sleep so you can renergize and help your body to get back to peak performance through sleep and rest. This is based on the theory that your body needs a fair amount of rest to help you perform your daily activities and tasks. With the circadian theory you have and internal clock that tell you when you need to sleep. Sometimes it is hard for people who are starting a night schedule to adjust because their internal clock does not know what time it is. This theory does not coincide with the theory of recuperation each theory has a different logic about how sleep affects us and what determines it 2. Which theory do you most agree with? Explain. Though I think that it can be a mix of both theories I think that recuperation is what I believe in more I think that the body needs rest in order to function properly I have went through my day or have went to work with very little sleep, ironically today being one of those days I also worked nine hours on top of that. The only thing I feel like doing right now is getting a hot bath and then going to bed. I also think that when you do not get enough sleep your personality changes I become a emotional wreck crying or getting very mad over illogical things. So to me from personal experience I think recuperation is what makes more logical sense to me.
