View full lesson: http://ed.ted.com/lessons/the-benefits-of-a-good-night-s-sleep-shai-marcu 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.

Anyone have any tips on how I can reset my sleep schedule? I've been sleeping at 2 and waking up at 7 just because I can't fall asleep

I suffer since 4 years because of lacking of sleep I spend my collage years tired, sick, nervious and angry. It affect on my communication and marks in exams. This is really hard even after 4 months from graduation I cant sleep early but I have to wake up early. I have nothing to do with this but I think sleeping well can make my life better.

If sleep is so important then why does highschool start so soon and why do they give us so much homework everyday?

Don't you hate it when you get to the good part of your dream, you wake up? It pisses me off. Nothing wakes you up for the entire night. Then, the second your dream starts getting interesting, the simplest noise wakes you up.

Well to be perfectly honest, in my humble opinion, of course without offending anyone who thinks differently from my point of view, but also by looking into this matter in a different perspective and without being condemning of one's view's and by trying to make it objectified, and by considering each and every one's valid opinion, I honestly believe that I completely forgot what I was going to say.

4:49 Why sleep 3 hours for declarative and 1 hour for procedural? Is it because one sleep cycle consists of a longer REM period than Slow Wave?

Ryan Leslie (6 months ago)
My question is this: why isn't this crucial piece of information made common knowledge to everyone around the world? I'm currently reading "Why We Sleep" by Matthew Walker and honestly, I've never looked forward to sleeping as much as now. I just wish I knew about all these benefits far sooner. I think school kids should be informed about this and parents need to understand that they do need that extra sleep. It's not being lazy, it's maintaining healthy optimum brain function.

This's wrong me and my friend are examples to disprove this theory I sleep a8-10 hours and can't remember what I ate yesterday. While my friend sleeps 4 hours average and she remembers what I was wearing a year ago.

Black Screen Education (11 months ago)
Great video! The explanation was very informative and animation superb. This is one of the best videos in terms of animation quality I've seen for a long time. I love your channel. Keep sharing useful stuff like this. Btw it's better to learn 2 hours and sleep for 8 then learn for six hours and sleep for two 😊
