Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in twenty-first-century society, with devastating consequences: every major disease in the developed world - Alzheimer's, cancer, obesity, diabetes - has very strong causal links to deficient sleep.

In this talk, Professor Matthew Walker explores twenty years of cutting-edge research to solve the mystery of why sleep matters. Looking at creatures from across the animal kingdom as well as major human studies, he delves into everything from what really happens during REM sleep to how caffeine and alcohol affect sleep and why our sleep patterns change across a lifetime, transforming our appreciation of the extraordinary phenomenon that safeguards our existence.

    My son is high achiever and an excellent all rounder. I was asked by an impressed school teacher how he did it. I said, well he sleeps a lot. The teacher was not at all happy with my answer, but it's the truth. As you sleep, so shall you reap. If you sleep a lot and get well rested, you will reap a lot when you are awake.

    It strikes me how deleterious hospitals are for sick people as it's almost impossible to get a decent unbroken nights sleep due to noise, heat, lack of ventilation, constant checking of patients throughout the night. It's interesting to see how much people improve when back home and into their own beds particularly older people.

    Ever since I was around 12 I have created and added to a fantasy grouping of worlds in my head and each night I visit this place and live in its forests, swim beneath its waterfalls and fly between its planets. I have homes that occupy my planets and furnish rooms down to the dinner plates and cushions. I have never had any problem sleeping, as soon as I go there I feel myself sinking. Start creating your own worlds. Start yourself of in a field in a valley, walk up the hill to get a better view of what lies beyond and take it from there. You will be asleep in no time.
  • Professor Matthew Walker is such an eloquent speaker, he really makes the subject of sleep very pertinent and clear. Thank you
  • @nohomo502
    Absolutely nothing I love more than sleep but since the smartphone era, I’ve never slept so little in my life. Truly the mark of the beast
  • This man is stunningly impressive - so logical and we just don't give sleep sufficient credence
  • @Migonper
    Its funny that im losing sleep by watching this late at night
  • @babington4394
    I think for those anxious insomniacs like myself, Mathew should place less emphasis on the dangers of less sleep and more emphasis on the benefits of more sleep. It’ll leave us excited for the next sleep rather than worried for it.

    "Doctors should advice the important of sleep to patients" Me on my 36th hr of a sleepless shift telling my patient to sleep more 😭
  • Wonderful, I am a neurologist and I have been stressing on the importance of normal circadian sleep rhythm and quality for all organs and all brain and body functions . I will translate this video to my patients 💕
  • @Tranzisto
    Whoever edited this deserves some praise for the fact that he cut out the introduction. Those are really unnecessary in the internet videos in my opinion.
  • I sleep a lot, i just love it, i have fantastic journeys while i sleep,and i enjoy my sleep life much better than my real one. I meditate and have a sleep during the day. But i wake up every night at 4am,i then go back to sleep, but it is always4am. I can go back to a dream that i want to,time and again.

    I just read his book a few months ago and here he is. As a single mum, I've been fatigued forever. Now that I am retired I can get the sleep I need. The problem is I always feel guilty sleeping too many hours.
  • Thanks so much from one who has not being sleeping well, all my life.
  • @siphannasam7554
