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.

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

    Evolutionary theories often emphasize that humans have adapted to their physical environment. One such theory hypothesizes that people should spontaneously follow a 24-hour cycle of sleeping and waking—even if they are not exposed to the usual pattern of sunlight. To test this notion, eight paid volunteers were placed (individually)b in a room in which there was no light from the outside and no clocks or other indications of time. They could turn the lights no and off as they wished. After a month in the room, each individual tended to develop a steady cycle. Their cycle at the end of the study was as follows: 25, 27, 25, 23, 24, 25, 26, and 25.…

    1. Let me suggest an idea about the adaptive function of sleep: It did not originally evolve for rest and repair (though those functions may have been layered on later, at least in some species). Instead, I’ll propose that its primary function is to keep the organism out of harm’s way during phases to which it is poorly adapted. For example, day and night can differ dramatically in lighting, temperature, humidity, abundance and type of predators and prey, etc., so an organism that was well adapted to one set of conditions would be relatively poorly adapted to the other. According to this hypothesis, sleep helps organisms avoid temporal regions of lower fitness.…

    Sleep is believed to function as a means of restoring the biological system to a better working order this is the basis of the restoration theory, Sleep is divided into several different stages such as SWS, and REM sleep, Oswald proposed that each of these sleep stages has a different restorative function. SWS enables the body to repair itself and REM enables brain recovery and memory consolidation.…

    Generally people need to sleep one hour for every two hours awake, and we need eight hours. The brain keeps an exact account of how much sleep it is owed. The brain tries to hit this mark, and the further you get from this number of hours the harder the brain tries to force you to go to sleep.…

    Circadian rhythms occur every 24 hours; an example of a circadian rhythm is the sleep-waking cycle. We are diurnal animals who are active during the daytime and asleep at night, other animals are nocturnal they are active at night but asleep during the day. The circadian rhythm depends on the interaction of physiological and psychological processes to be tuned into the sleep-waking cycle so energy is provided when needed. As diurnal humans we have a fairly stable sleep pattern with the time we go to sleep and the time we wake up, this consistency suggests an internal mechanism controls sleep, endogenous pacemaker. However, this can be overridden by external factors, exogenous zeitgebers.…

    There are three main biological rhythms, which are called infradian, circadian and ultradian. Ultradian rhythms occur multiple times in one day. Circadian rhythms are cycles, which occur once a day, so within the 24 hours such as the sleep-wake cycle. Infradian rhythms are less frequent once in a day such as the menstrual cycle or hibernation. The research into these rhythms offers an insight into how the body is influenced by exogenous zeitgebers and endogenous pacemakers, but it is still nonetheless unclear what it more influential.…

    Sleep is very important to the regulation of the body 's functions. Sleep is regulated by circadian rhythms. The circadian rhythm is controlled in the brain by an area called the suprachiasmatic nucleus which controlls around 20,000 neurons. These rhythms determine the ideal times for structured and restorative sleep and are generlly in 24 hour cycles. The exact functions of sleep are not exactly known however, those who are sleep deprived have been found to have weakened immune systems and poor brain function. According to the National Institute of Neurological Disorders and Stroke (2007), sleep gives neurons used while we are awake time to repair and that without this shutdown time they become depleted of energy and begin to malfunction. Sleep is also believed to give the brain a chance to exercise important connections that might otherwise deteriorate due to inactivity.…

    The evolutionary explanation (also referred to as the ecological approach) is based on the observation of animals in their natural environment. The evolutionary approach to sleep has focused on ecological niches. These refer to the lifestyle of animals, i.e how and where they live, and involves many factors that have been shown to be relevant to sleep. The evolutionary approach states that there are several beneficial consequences to sleep. For example, it allows for energy conservation; it provides a period of time where there is no activity, thus allowing the conservation of energy which is essential for animals with high metabolic rates. Webb suggested that everyday sleep is similar to hibernation - sleep conserves energy at times when it’s harder to get resources (i.e at night time). Meddis suggested that sleep helps keep animals safe. By being quiet and still, they’re less likely to attract predators. However, sleep also makes animals vulnerable to predators if discovered. On the other hand, not sleeping at all would be very dangerous, but as it seems to occur in all animals, it must have an important function - although how much sleep animals have varies. Animals that graze often and must avoid predators less, while predators, that don’t eat as frequently and aren’t hunted, sleep more.…

    Sleep plays an important role in our lives. From tiny insects to humongus grizzly bears, every living thing needs sleep. We need it to carry out our daily activities and to live a long and healthy life. Many people fail to realize that sleep is as equally important as breathing, and because of this their bodys are not functioning to their full potentials. Not getting the amount of sleep your body needs can lead to mental and physical health problems. Lack of sleep impairs the mind's way of thinking, can cause health issues and affect your judgment and mood. Sleep is a vital part of life.…

    What is sleep, and is it possible that we might change our sleep patterns to reduce the number if hours of sleep we need? All animals including humans need sleep. For a period of time during each twenty four hours every living creature must spend more time in a state of sleep. During this time, the bodily functions slow down and the individual “loses consciousness” or becomes unaware of noise or movement. The amount of sleep we need varies from species to species and even from individual to individual. Different people need different amounts of sleep, from 1 1/2 hours a day to 12 hours a day, but it appears that most normal adults need an average of 7 1/2 hours a day. The need for sleep also changes according to age: babies need more sleep than most adults and as we get older we need less sleep. In any case, we spend a lot of our time sleeping or feeling tired if we don’t get enough sleep. Many people feel that sleeping 7 or 8 hours a day is a waste of time. It would be nice if we could limit the amount of sleep we need to only a couple of hours a day so we would have more time to do the things we enjoy or to make money. Leonardo da Vinci, who was a very productive individual, seemed to find the secret for gaining more hours in the day. He discovered that if he behaved more like a baby or a cat, that is, taking “catnaps” throughout the day for short periods of time instead of sleeping for one long period of many hours, he was able to stay alert and continue his work. In the way he reduced his sleeping time to 90 minutes during 24 hours.…
