  • We spend 1/3rd of our life asleep, which suggests it is doing something very important. But, what is all of this for? And why does every animal species appear to need sleep? Based on the latest neuroscientific research Penny Lewis shows why sleep is thought to be critical for combining and restructuring memories, and thus to form the basis of creativity.
    Penny (Penelope) Lewis is a neuroscientist at the University of Manchester, where she runs the Neuroscience and Psychology of Sleep (NaPS) lab. Her research investigates the role of sleep in strengthening and altering memories and the ways people can use this to their advantage. She is the author of The Secret World of Sleep, which has sold around 10,000 copies, and has written for a variety of popular science publications, including New Scientist, Scientific American and BBC Focus.
    This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at ted.com/tedx

    The title is a lie, there is no scientific method presented as to improve sleep. Typical professor, she flashes her knowledge to us little people and that's it, thats all. Oh yes, with a lame "professor joke" to close her talk.
    And now she can proudly add being a Ted talker to her résumé

    I understand that improvement of traumatic memories. It seems that if you go or the moment of trauma by writing down the memory of it's triggers it is much easier to overcome than if you squelch or try to suppress the memories, which just come back in some tortured, altered form.

    Dr. Lewis, I would love to suggest that a subject for study could be the cognitive/memory impairment experienced post cancer treatment and wondering if either chemo is affecting REM sleep (long term) or the subsequent aromatase inhibitor therapy for certain cancers has an effect on sleep cycles. can't find anything on my (limited) google search.

    Making this simple for my dummies -
    If we were cars. Sleep will be our three month monthly servicing (tire rotation, oil change, tune up, liquid flush/topoff). 1
    If we were phones. Sleep will be daily maintenance (charging, system cleanse, software updates).

    For me it's the opposite, I suffer from hypersomnia. And it's really awful. There are people who suffer from hypersomnia who are much worse than me, but I can sleep on vacation for 17 hours and still feel tired. I also get a horrible headache from it and can't concentrate or think properly. And I've lost the ability to wake up on my own despite having multiple alarms, I can just walk to the other side of the room turn it down and go back to sleep. Often times, I don't want to sleep but still feel sleepy. I wish I could get rid of this condition.

    Quite engaging talk. Love the idea to level up our sleep quality.
    I will go ahead and will test this idea. So, I want to complete design of my notes system in Google Keep, picking right labels and colors in a way it fits best, so I can always keep and find my ideas with maximum eaze. And I'm writing about this problem and listening to "rain with occasional thunderstorm" sounds and going to turn it sound again at night.
    Questions I have: how can we practically define the time when the associative sounds should be played?

One minute in this vid I can almost guarantee this video won't enlighten me to anything helpful. I'm actually optimistically being pessimistic hoping I'm wrong. Let's see....

    I noticed several years ago that I would make significant improvements overnight. I'd practice and practice something and not get much better during the day. Like juggling or playing piano. I could practice for several hours and slowly get a little bit better, but once awakening the next day I would be far better and make similarly small improvement that day, and then be much better after sleeping. I noticed this as a teenager. I'm sure I'm not the only one.

  • Marc Thibodeau
    Marc Thibodeau 6 months ago

    This was really an eyes opening speech. I simply enjoy sleeping as when I wake up I always feel refresh and usually my problems are simpler when I wake up. It is nice to ear that I am considered normal according to here standard. My secret is no medications and no attempts to try improving artificially what is going on for me. It is nice to see how far the research on sleeps has advanced. I strongly believe that helping people having sleeping disorders regaining the pleasure to sleep should be the focus for now. This is already plenty which can do so much good. The cleanup of toxines occurring only while sleeping seem so important as there is so much toxins created by the addictive processed food that we keep eating. Thank you for sharing. Next time I sleep I will filter out some of my negative attitude on that topic which make me believe that some companies will try to prematurely sell products based on pseudo science on the topic. Thank you for sharing and have a pleasant day.

    Excellent video! Dr. Lewis clearly explains how learning can occur during the evening. The video helps me understand from a scientific standpoint how a musician can somehow play an instrument without constantly looking at the piano keyboard or the guitar neck. The brain needs time to learn, and it will..... as long as we allow our brains to be connected with content knowledge during the day and to "make progress" during our sleep. When acquiring knowledge, progress is a sequential process of days and nights. Therefore, time is a crucial factor in learning processes. Dr. Lewis, thank you for an excellent video. Thank you, TED.

    I wasn't going to comment but then the more I thought about it the more annoyed I was. Spoiler: If you are watching this video hoping it will tell you how you can manipulate your sleep to improve your life...it wont' tell you that. The information is interesting but it ultimately leads to nothing that can help you now, today. I listened to this while I was working on very spotty wifi. It kept stopping and starting so it took much longer than 16 minutes to get though it. But I though, hey if it can help then its worth it. With about 1 minute left I realized there was not enough time for her to tell us the solution. So we end with problems and information but not much else.
