The benefits of a good night's sleep - Shai Marcu

View full lesson: ed.ted.com/lessons/the-benefit...
It’s 4am, and the big test is in 8 hours. You’ve been studying for days, but you still don’t feel ready. Should you drink another cup of coffee and spend the next few hours cramming? Or should you go to sleep? Shai Marcu defends the latter option, showing how sleep restructures your brain in a way that’s crucial for how our memory works.
Lesson by Shai Marcu, animation by Javier Saldeña.

    Girl. I sleep for like 10 hours and my memories are basically permanent My tutor has noticed this and just had me look at every page that’s necessary for me to pass the exam ONLY once, then that’s it. I go to sleep. Next year, she shows me the same questions. I asked her why we’re looking at the same questions when i still remember the answers (yes, i still remember after 1 whole year), and she said it was to make sure students still had it right, lol. That should tell you alone how much important sleep is ^^ I can’t live without sleeping I legit love it so much, i used to sleep for around 16 hours for a entire week (that’s actually unhealthy, oversleeping), but my body just randomly decided to want to sleep for around 16 hours so I don’t know why + i actually had awesome rest, that was the best rest I got ever. It stopped after a week. Randomly came in, then stopped after a week, so weird.

    Hemzok you have temporary memories. Reading something once, then sleeping, will create a stronger memory than reading something 5 times and not sleeping. That's why these "magical" people with "magically great" memories can "waste time" sleeping. They're actually studying more efficiently than the people who stay up all night, beating their brains up with information over and over and starving their mind of the chance to actually retain any of it. Repeating studies over and over again is the true waste of time. We all have the same brain; same parts. If someone is having an easier time than you, don't accuse them of being lazy - ask them what they're doing right.

Actually, it has been a week since I'm trying to sleep and wake up earlier, and I noticed a huge differences - I started to memorize an information in a shorter time and remember it for long time. Also, before I felt sleepy during the whole day, even tho I slept 8 full hours. Also I did not have mood to do anything. In fact, when I started to sleep earlier, around 10-11pm, I felt that during the day, I was happier and I was very productive. This is an issue that today most of the college students face.

For the better grades, study the definitions, solve lots of exercises that whenever you see a problem, the solution comes to your mind. I am talking about Math, chemistry and physics.

    Many advances on pyschology and neuroscience in general were made in the post-war periods, because they would have a lot of people with damaged brains to study. Each person could have a particular part of the brain inactive due to a bullet or trauma etc., so they would observe what this damage caused to the person's behavior and then make hypothesis about that particular part of the brain being responsible for a particular group of tasks. Today we have much more technology to study people's behavior with real-time neuroimaging and many more techniques.

    The Benefits of a Good Night’s Sleep (Transcrição) It’s 4 a.m., and the big test is in eight hours, followed by a piano recital. You’ve been studying and playing for days, but you still don’t feel ready for either. So, what can you do? Well, you can drink another cup of coffee and spend the next few hours cramming and practicing, but believe it or not, you might be better off closing the books, putting away the music, and going to sleep. Sleep occupies nearly a third of our lives, but many of us give surprisingly little attention and care to it. This neglect is often the result of a major misunderstanding. Sleep isn’t lost time, or just a way to rest when all our important work is done. Instead, it’s a critical function, during which your body balances and regulates its vital systems, affecting respiration and regulating everything from circulation to growth and immune response. That’s great, but you can worry about all those things after this test, right? Well, not so fast. It turns out that sleep is also crucial for your brain, with a fifth of your body’s circulatory blood being channeled to it as you drift off. And what goes on in your brain while you sleep is an intensely active period of restructuring that’s crucial for how our memory works. At first glance, our ability to remember things doesn’t seem very impressive at all. 19th century psychologist Herman Ebbinghaus demonstrated that we normally forget 40% of new material within the first twenty minutes, a phenomenon known as the forgetting curve. But this loss can be prevented through memory consolidation, the process by which information is moved from our fleeting short-term memory to our more durable long-term memory. This consolidation occurs with the help of a major part of the brain, known as the hippocampus. Its role in long-term memory formation was demonstrated in the 1950s by Brenda Milner in her research with a patient known as H.M. After having his hippocampus removed, H.M.’s ability to form new short-term memories was damaged, but he was able to learn physical tasks through repetition. Due to the removal of his hippocampus, H.M.’s ability to form long-term memories was also damaged. What this case revealed, among other things, was that the hippocampus was specifically involved in the consolidation of long-term declarative memory, such as the facts and concepts you need to remember for that test, rather than procedural memory, such as the finger movements you need to master for that recital. Milner’s findings, along with work by Eric Kandel in the 90’s, have given us our current model of how this consolidation process works. Sensory data is initially transcribed and temporarily recorded in the neurons as short-term memory. From there, it travels to the hippocampus, which strengthens and enhances the neurons in that cortical area. Thanks to the phenomenon of neuroplasticity, new synaptic buds are formed, allowing new connections between neurons, and strengthening the neural network where the information will be returned as long-term memory. So why do we remember some things and not others? Well, there are a few ways to influence the extent and effectiveness of memory retention. For example, memories that are formed in times of heightened feeling, or even stress, will be better recorded due to the hippocampus’ link with emotion. But one of the major factors contributing to memory consolidation is, you guessed it, a good night’s sleep. Sleep is composed of four stages, the deepest of which are known as slow-wave sleep and rapid eye movement. EEG machines monitoring people during these stages have shown electrical impulses moving between the brainstem, hippocampus, thalamus, and cortex, which serve as relay stations of memory formation. And the different stages of sleep have been shown to help consolidate different types of memories. During the non-REM slow-wave sleep, declarative memory is encoded into a temporary store in the anterior part of the hippocampus. Through a continuing dialogue between the cortex and hippocampus, it is then repeatedly reactivated, driving its gradual redistribution to long-term storage in the cortex. REM sleep, on the other hand, with its similarity to waking brain activity, is associated with the consolidation of procedural memory. So based on the studies, going to sleep three hours after memorizing your formulas and one hour after practicing your scales would be the most ideal. So hopefully you can see now that skimping on sleep not only harms your long-term health, but actually makes it less likely that you’ll retain all that knowledge and practice from the previous night, all of which just goes to affirm the wisdom of the phrase, “Sleep on it.” When you think about all the internal restructuring and forming of new connections that occurs while you slumber, you could even say that proper sleep will have you waking up every morning with a new and improved brain, ready to face the challenges ahead.

    +Garrett Oehlerking personally, I'm actually the type that rather sleep than forcing myself reading materials. Obviously, the proper thing is to study way before the test come close. But when in a pinch, I sleep early so that I can wake up early, and then study. Because even in both cases you have less sleep, but you have more energy learning after the sleep rathen than before sleep.

You can struggle to play something before going to sleep. You wake up next morning and you know how to play far better ! I'm just a bit frustrated that the video explains very well how the consolidation process works with declarative memory, yet it tells us almost anything about the process of procedural memory consolidation. But the 3 and 1 hour before sleeping information is golden.

    So I used to have extremely bad insomnia where I’d sleep past 4 am every day and wake up at sometimes 7 am to 8 pm, but I knew it was terrible for me. So I decided that I’d force myself to wake up at 7 am and sleep at 11 pm. How? I made sure to do many things in a day whether it was running, doing homework, work, or just something that takes energy and or makes you productive. Then, at the end of the day, I would be tired of it all and rest would be perfect right at my curfew that I enforced. I know it sounds simple but it really isn’t since starting is definitely the hardest part. I feel much better now! 😅 thanks for reading

    The concept of sleep importance is incredibly vital for us college students who often neglect their 8 hours to study or party or work. I am guilty of this as well which is why this video is so important. Many of us know that sleep is important but wouldn't guess that it makes such a difference in the information we retain from day to day. I was interested to learn that the main factor contributing to memory consolidation is SLEEP! At the time, it might not make much sense to give up cramming and get some sleep, but when you look at all the facts and benefits, it's hard to argue otherwise!

    I have realized years ago that 1 hour of sleep is always worth more than 1 hour of learning before a test. However one day before a test you don't really need to save the stuff in the long term storage, short term is enough. And unfortunately in my case stuff that I learn right before going to bed is being saved extremely well in my short term memory but hardly at all in the long term. So for me it really only is a solution a day before a test, given that the test requires pure learning and no logical thinking, because this requires concentration and experience rather then pure memory.

    One day I was trying to learn a song kept singing along to it the whole day but still wasn’t able to remember more than 1 line by the end of the day. next day when I woke up i surprisingly knew all the lyrics, it’s like my brain memorized it while asleep.

    There are people who preach others to Stop watching KZread videos in the name of popularity but never understand that they have gems of educational importance in it. Be positive. TedEd is awesome and thank you KZread for everything ❤.

    So accurate! I am struggling at University because I simply cannot fall asleep for hours, even going to bed with 10 hours to sleep. So frustrating how I can't retain any information from the previous day even with continuous hours of intensive study :(

    This is a great video to understand the importance of sleep! With a great animation and sequence. However, there's some info that you didn't reveal, like explaining more about the consolidation of procedural memories. But, forgetting this, this video is perfect.

    This should be taught in school. When I was in secondary school, I don't know what exactly I want to do and I just sit down at my desk as long as my mother wanted (until over 23pm). Later, in high school, this habit still continued. I didn't learn anything more and just waste time sit down at my desk. I think this is the reason why I couldnt be taller after 11 years old.

    On average I get around 9 hours of sleep. When I get a lot of sleep, I experience not feeling as tired and remembering more of my school work from the night before, like the video said. Sleep can effect your health in many ways. For example, if you do not get enough sleep you will not retain as much knowledge from the night before compared to someone who did get enough sleep. Also, sleep can alter your mood which can effect your health.
