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.

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.

[@ShawnPhelpsVlog]

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.

Sleep is important for everyone! I am a college student who likes to finish the assignments later at night, even tho if I have to sleep at 4am. 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.

Im just very curious to know because I myself am terrible when it come to organisation and structure ie : not doing/preparing my exam at the last minute!

@@littleuzib1052 Actually I also take those subjects in my University, and I can say that you gotta study concentrated. You don't have to do like more than 3 or 4 hours per day, and try solving problems. 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. For the organization, you have to create a timetable for you, and most importantly, don't break the rules. Actually for late submission, we have something that our grade gets deducted.

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.

Poetically ironic

Addison’s voice is so calming. I wish I could listen to his voice while trying to sleep.

[@Ness95]

Oh, yes. You're right, I'm going to do that

[@MrCuddleBear1]

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

[@starlostgirlie]

do your memories get better or smtg like in the video?

[@luvylu1]

I have 7 essays to finish by this morning and I can't go to sleep until I finish them, yet here I am procrastinating and watching a video about sleep.

[@Jonnie153]

did u survive

[@nakedking6676]

+Phone Apparently, no, I guess. I feel bad for him and also for everyone in the world including myself

[@joecurran2811]

How did that go? xD

[@nirv2796]

dang thats imposible

[@kylenetherwood8734]

That clock in the brain with the 20 minute 40% thing was so cool.

[@unnainconnu9098]

Yeah, it would have been great if it showed 40 % instead of 33 % (20/60). So close! :-(

[@softmusicforsleeping4075]

Thank you so much for this relaxing video 💚💚💚

[@adharshk2838]

The music in the whole video made me sleep a little bit🤣😂

[@NicosRap]

Of course I'm watching this at Midnight...

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!

[@Solusspiritus]

How was college? Still getting 8 hours?

[@notRealCapedBaldy]

I honestly sincerely genuinely would like to know the benefits of a good morning's sleep.

[@shruti2277]

I will sleep on time 😴 as it helps in remembering things. It can also increase our energy for the next day activities.

[@Zetsuke4]

Thank you very much for this video! I've been sleeping 2 to 5 hours everyday for months, and I feel like utter shit. Now, I will aggressively eliminate every threats that cause me to lack sleep! Now I know sleep is extremely important!

[@XPimKossibleX]

oof man 2-5 hours do. you must. aim for about 10 hours for now.

[@Zetsuke4]

It's been several days since I posted this comment, and I still sadly get 3 to 4 hours of sleep everyday. I have so much work to do. :(

[@XPimKossibleX]

Zetsuke4 if the decision is between working more and sleeping more, always choose sleep. work will be better. unless you're on wages, in which case ahhhh evaluate life. tons of stuff can happen from lack of sleep such as insomnia! which will make you lack more sleep and feed into the loop.

[@luizclaudio6724]

how is your sleep going?

[@fademoran]

Zetsuke4 I’ve had

[@papado9537]

me: shows video to school school: We don’t do that here

[@karlavides7769]

I love it! Pretty good information and learned in a fun way!

[@nelaepowt]

Really cool! I'm struggling with sleep right now because of my projects, so I'll keep this in mind.

[@zilvoxidgod]

The benefits of a good night's sleep sound great, too bad I'll never experience them.

[@wasifshaffaq]

why though?

[@skups3843]

It's 4 am in the morning... Me: *watching at 4am in the morning being worried that I am being watched by TED-Ed* *_confused screaming_*

[@neo-xy3fr]

I like to stay up late because I feel like sleep is a waste of time. There's so much to do specially when it's quiet and no one to bother you

[@kubakuba2247]

True mate! The day is simply too short

[@samsunguser3148]

Same thinking.

[@edpscupcake815]

Sleeps important

[@sheikfareed8012]

Just loved this piece of information! Gonna sleep at once as it's already 12:15 am.

[@joannajoel]

Ah! Thank you so much TED! I've been going through depression when people around me where laughing at me for sleeping 8 hours a day. They say youbarent a child. And they sleep for around 4-5 hours only. Now I'm relieved! 💖💖💖

[@jararacavoadora5868]

These people are sick. Most people here in my city sleeps for 7 - 8 hours, some of them even 9

[@thejerkyshack8040]

I'm watching this past midnight is it ironic

[@gulipink7143]

me too

[@andersyu4464]

more than 8 hours past midnight?

[@mariachristymomongan9444]

It's normall👌

[@StarBoundFables]

That's awesome! I love getting a full night's rest & envisioning my bed as a vessel which transports my consciousness to the Dreaming City 🙏🏼

[@leilamanchino]

That’s so cool! It kind of reminds me of the movie inside out

[@phongnguyen-sd6zl]

I've incorporated this lecture in my study at school. As a result, I couldn't remember anything taught by my teacher since I've fallen into slumber too many times at class

[@carolyn2420]

The whole time I was distracted by the designs and colors

[@jorgeantoniocab49]

+Carolyn Nicole you have attention issues

[@user-eg3zs6oi7c]

+Carolyn Nicole the same thing happens to me when i go to the beach. those girls with their bikinis and those colors. too distracting.

[@BETORAMIREZ664]

I thought i was the only one who had that problem!!! I thought it was that being at sea level affected my blood circulation to my brain, cause up by the mountains at 5500 ft above sea level that doesn't happen to me at all; and there aren't any girls in bikini either!!!!

[@SepSol75]

they are so beautiful

[@ronitpatel3696]

The song was also disturbed

[@chasemanhart]

As I stay up watching this late at night

[@AriaSenz]

We need a teacher like him to teach our teachers :)

[@arnavkumar7910]

When I have to mug up a whole book before exam, a good night sleep will autosave all the important information. Truly works. I am here after giving my Science exam. Love from India

[@colbonthecob2530]

Can't wait to forget about the forgetting curve haha. I've been binge watching episodes and I've absorbed so much information I may explode.

[@Owlcrafter]

Its 3:am where am at and I just watched this and love the tips i just learned. Too bad im not likely to remember this

[@bemyself7025]

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.

[@mrman5066]

School: I'm boutta end this man's whole memory formation cycle

[@pikherz]

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.

[@priceunboxing6047]

though i had prepared very well i failed an exam for the first time in my life when i slept only two hours the night before exam. , but next day i slept full eight hours and i got A in another...

[@Aftershock_Flatline]

*proceeds to watch over and over again at 1 in the morning, then ended up watching it for hours while trying to fill out the quiz*

[@ClaireSamuelsVA]

When you’re a neuroscience major and you know all of this by heart but you watch it anyway to guilt yourself into going to sleep

[@dave5194]

Thank you, this is very useful, I don't get nearly enough, around 4 or 2 hours a day, except on week ends

[@jaumeproduccions2236]

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.

[@iwbmo]

heyyy a fellow doge

[@wellbodisalone]

Seeing that more people are getting interested in this topic is so good.

[@keisha.dechaca]

2 years ago istarted to experimwnt on the sleeping pattern that works best for me and i figured that sleeping early and waking up early (9pm-4am) to do intensive school works is soooo much better than staying up late and waking up late the next day. Been doing it since then;It increases will power, improves comprehension, mood, and you still have good sleep.

[@starlostgirlie]

really?

[@hafsaabid7454]

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.

[@radgestudios]

The irony of watching this at 3 in the morning...

[@SREETAM_D]

its 3:33 AM here :)

[@helfrianammarmusyaffa9079]

Same:)

[@baoduong185]

It is so meaningful, i have been studying many knowledge from this video, thank you so much. i from Vietnam

[@chunyanmi5643]

I have not been had a good sleep since I was little. I know a lot of my neighbors and friends in my same age are the same. But we still be our best to be good. So proud of ourselves.

[@clint9527]

Watching this at 1:25 AM instead of sleeping

[@TakeshixStudios]

Watching at 5am after late night shift xD

[@sitiramla9927]

Thank you, for your information, Made me aware of the importance of sleep

[@Wanderers-Bulgaria]

I had thoughts that sleep is a lost of time. I am happy now with myself, what I am and who I am. 🙏☀️
