  • Sleep actually enhances your memory and it refreshes your learning ability.

  • You need sleep after learning to essentially hit the save button on those new

  • memories, so that you don't forget.

  • But what we've also learned is that you need

  • sleep before learning as well and now -to almost prepare your brain, a little bit

  • like a dry sponge ready to initially soak up new information. So you need

  • sleep on both sides of that equation and that's why pulling the all-nighter

  • before the exam is a very bad idea.

  • When you sleep you actually see almost a

  • three-fold increase in creative abilities as a consequence and there's

  • some wonderful anecdotes demonstrating this sleep inspired creative benefit.

  • Keith Richards, from the Rolling Stones, actually used to go to sleep with a

  • guitar and a tape recorder because he understood the power of dream sleep, what

  • we call REM sleep, and he describes in his autobiography how one night he

  • started the tape recorder, went to sleep and the next morning the

  • tape had run all the way through, he rewinded it back and there in some ghostly

  • vision were the opening chords of Satisfaction,

  • the most famous Rolling Stones song.

  • And then he said it was followed by about 43 minutes of snoring thereafter.

  • It's probably the reason that no one has ever told you

  • to stay awake on a problem.

  • Sleep is a wonderful health panacea. Every major disease that seems to be

  • killing us in the developed world has significant -and many of them causal-

  • links to a lack of sleep. So the two most feared diseases,

  • which are Alzheimer's disease and cancer, both have strong links

  • to short sleep duration across the lifespan.

  • Short sleep will actually predict all cause mortality. So you may

  • have heard that old maxim people would tell you that "you can sleep when you're dead".

  • Well, it is mortally unwise advice if you adopt that mindset.

  • We know from the science that you will be both dead sooner

  • and the quality of that now shorter life will be significantly worse.

  • Less sleep does not equal more productivity, it's a fallacy that still

  • remains in business and it's actually a very costly one too. The RAND Corporation

  • several years ago performed a global survey of the cost of sleep deprivation

  • across nations and what they found was that insufficient sleep within the

  • workplace cost most nations about two percent of their GDP. So, just think about

  • that, if we could solve the sleep crisis within the workplace we could perhaps

  • double the budget for education, maybe we could even half the healthcare deficit

  • that were suffering in most of these developed nations. So sound sleep is

  • sound business, that's exactly what the science teaches us.

Sleep actually enhances your memory and it refreshes your learning ability.
