Sleep and Learning
Sleep is quite a complex phenomenon We arent exactly sure how it works though But studies both in animals and in humans show that quality and quantity of sleep affect memory and learning It is supposed to work due to two factors One of them Is the inability to focus when you are sleep deprived Because of this inability people cannot be optimally attentive and so they lack the capability to learn effectively But also it is thought to work via a process called memory consolidation
Now what is consolidation Well several terms are important when we talk about leaning Acquisition means introducing something new in your brain Consolidation is the process of stabilizing this memory Then we have recall which is the process of accessing the information at a later moment
Those steps have a great impact on the memory Acquisition and recall can only occur when we are awake Still according to research we can imagine that consolidation occurs during sleep via strengthening the neural connections that are the basis of our memory
Sure there isnt a consensus yet on the topic But it is thought that the brainwaves of our brain during the sleep stages have effect on the formation of some kinds of memory
Stages of Sleep Kinds of Memory
The studies that were first done were focused on what is called declarative memory This is the knowledge of various facts Scientists proposed a hypothesis that said that probably REM rapid eye movement stage of sleep had association with acquisition the material that has been learned Studies done afterwards pointed out that REM plays a part in declarative memory for complex or emotional charged information but it did not seem so for neutral and simple information
Nowadays scientists think that maybe slow wave sleep or the so called SWS stage has a significant role in this process During SWS we sleep deeply and this is the restorative stage of the sleep cycle It is hypothesized that maybe it helps consolidate the newly learned information This is still under research and shows mixed results
Sleep and procedural memory also is a topic for research Procedural is the memory that keeps data on how to do something Its consolidation is tied to REM sleep
At the same time REM and SWS sleep affect visual learning while motor learning looks like it depends on lighter sleep stages
Deprivation of Sleep and Its Impact on Learning
Scientists have also looked into how sleep deprivation affects the learning process and our memory
Those who are sleep deprived often lack attention and focus
This then leads to more difficulties with receiving and processing information
When one isnt rested well enough and hasnt gotten enough sleep their neurons cannot properly coordinate information Thus in such scenarios we lack the capability of accessing data weve learned before
Also events interpretation can suffer We now cannot make proper decisions for we lack the ability to make plans and choose which behavior is correct
More on Snoozing and Memories
It seems like the non REM sleep stages are preparing our brains to learn effectively on the next day 40 drop of the learning ability can occur in those who havent slept All nighters arent efficient for learning Sleep deprivation affects the hippocampus and exactly this part of the brain is responsible for creating new memories
When we sleep the brain sorts out memories and chooses which ones it wants to keep and which ones not During the sleep cycle some of the memories are strengthened In this process REM plays a role It links memories together Sometimes it does so in unexpected manner So having a good night of sleep can work wonders for solving problems REM also allows us to process highly emotional memories This allows for reducing the intensity of those emotions
Conclusion
Yes we really do need our full 8 hours of sleep And this is due to many reasons Since listing them all would take a great deal of time and youll get bored reading it we decided to pinpoint one of the most important aspects sleep and its effects on learning
As you can see pulling all nighters wont seem to work Thus try to do your studies during the day and get a good nights sleep This is especially true if you have a test or an exam on the following day
There are various stages of sleep and they together constitute the sleep cycle We go through this cycle several times a night and allowing ourselves enough time to do that is vital for our health
And you are probably trying to find good tips on how to study more efficiently Well there is one step you can take right away sleep well By allowing yourself to rest for enough period of time you will be more capable of learning on the next day You will find out that you are feeling more energetic and you have better mood Also you shall see that memories seem to be stronger
So try to follow the guidelines of the health authorities They are suggesting that adults should sleep 7 8 hours a night Now go grab a pillow turn off the lamp and catch some Zs
Sleeping is incredibly important to everyday life but it couldnt be more important when you think about it in terms of studying and learning
Alaska Sleep Clinic takes you and your familys health seriously Dont trust your sleep to anyone else
