Oswalds Restoration Theory of Sleep :: essays research papers

A restorative guess claims that ease is used to repair the body including the instinct. Oswald suggests that dense wave calmness is when body repair occurs and rapid eye movement sleep is when the brain is repaired. This is alimented by the fact that there is an increase in the secernment of growth hormones during SWS. This could also explain why brain activity levels be high during paradoxical sleep sleep, and similar to when awake. Stern and Morgane back up Oswolds theory about paradoxical sleep sleep with their activation synthesis theory. They believe, with give birth from research that shows that when people take antidepressants, their REM sleep decreases, that REM sleep is a time for synthesizing nor-adrenaline and dopamine, which are used as antidepressants. This is however, a correlation coefficient study which means it doesnt show causality. Many studies of the role of sleep are partial or total sleep personnel casualty studies which support Oswolds restor ation theory. One of these supporting studies was Dements. He deprived participants of REM sleep and consequently found that they increased their number of attempted REM stages from 12 to 26 over 4-7 nights. During their first unoff-and-on(a) night, participants increased their REM sleep by 10% which is known as REM rebound. This suggests the importance of REM and the possibility that the purpose of sleep is to get into REM sleep. The participants inform anxiety, irritability and difficulty concentrating which shows that REM sleep is needed to avoid these affects and alter brain recovery which corresponds with Oswolds theory. Even so, Dements study has depleted ecological validity, it has low population validity because there were only 8 participants and they were a self-selected sample. Participants would probably have shown demand characteristics because the experiment took place in a lab. It also has low mundane realism because people would non usually sleep in a lab and be interrupted repeatedly. This is also unethical as it caused stress. A total sleep expiration study is even more than unethical and therefore difficult to get to participants for, but as a case study, Randy Gardner broke the beingness record. He suffered from paranoia and hallucinations as a result of the total sleep deprivation which again shows the importance of sleep. However it is not feasible to generalise to the all in all population from one self-selected participant. Further evidence to support Oswolds theory about SWS, comes from the idea that more physical exercise would lead to more SWS because the body needs more repair.
