Just as some students mistakenly spend hours and hours together studying in the hope that this will help them in their studies, so also some students think that cutting down on their sleeping hours will give them more time to study.
This however is wrong. While it has been known for some time now that insufficient sleep will cause various health problems like high blood pressure, obesity and diabetes and increase the risk of Alzheimer’s or Parkinson’s disease it has now been shown that sleep is of utmost importance even when it comes to improving the ability to learn.
Dr. Maiken Nedergaard, Professor of Neurosurgery at the University of Rochester conducted a study on mice and discovered that when the mice slept their brain cells shrank and there was an increase in the flow of cerebrospinal fluid. This increase flow of cerebrospinal fluid caused the harmful proteins that build up in the brains when the mice were awake to be washed away.
This according to Nedergaard could be the reason that we don’t think clearly if we have not slept properly the previous night.
Other studies have shown that sleep plays a very important role in Learning both before learning and after learning. Dr. Ines Wilhelm of the University of Tübingen's Institute for Medical Psychology and Behavioral Neurobiology studied the importance of sleep and found that it was very important for children to sleep well. This allowed children to absorb properly even things that were learned subconsciously.
