People dramatically underestimate how much sleep is linked to all the diseases killing us. We know a lack of sleep is linked to numerous forms of cancer – bowel, prostate, breast cancer. Matthew Walker Read Quote
Your subjective sense of how well you’re doing under conditions of sleep deprivation is a miserable predictor of, objectively, how you actually are doing. Matthew Walker Read Quote
I think we perhaps are, with sleep, where we were with smoking about 50 years ago, in that we had all of the science, and it was right there for the public discussion, but it’s not yet adequately sort of percolated out into policy or even just public wisdom. Matthew Walker Read Quote
That short-sleeping that we’re now suffering is a consequence of our lifestyle. It’s not a consequence of evolutionary habituation. Matthew Walker Read Quote
No one would look at an infant baby asleep, and say ‘What a lazy baby!’ We know sleeping is non-negotiable for a baby. But that notion is quickly abandoned. Matthew Walker Read Quote
Regularity is a key: going to bed at the same time, waking up at the same time no matter what. But I think, also, it’s not just about quantity – that’s what we’ve been discovering. It’s also about quality. Matthew Walker Read Quote
Many business leaders still believe that time on-task equates to productivity. Even in the industrial era of rote factory work, this was untrue. It is a misguided fallacy, and an expensive one, too. Every key facet required for business success will fail when sleep becomes short within an organisation. Matthew Walker Read Quote
Sleep-deprived individuals also generate fewer and less accurate solutions to problems. Matthew Walker Read Quote
No one wants to give up time with their family or entertainment, so they give up sleep instead. Matthew Walker Read Quote
The gross demonstration of caffeine is that it prevents you from falling asleep. The slightly more nefarious aspect of caffeine is that maybe you can fall asleep, but we know that the depth of deep sleep you’re getting if caffeine is still in your system is severely less. Matthew Walker Read Quote
