Matthew Walker
“Inadequate sleep—even moderate reductions for just one week—disrupts blood sugar levels so profoundly that you would be classified as pre-diabetic.”
Matthew Walker, Why We Sleep: Unlocking the Power of Sleep and Dreams

Matthew Walker
“After all, absence of evidence is not evidence of absence.”
Matthew Walker, Why We Sleep: Unlocking the Power of Sleep and Dreams

Morgan Housel
“Use money to gain control over your time, because not having control of your time is such a powerful and universal drag on happiness. The ability to do what you want, when you want, with who you want, for as long as you want to, pays the highest dividend that exists in finance.”
Morgan Housel, The Psychology of Money

Matthew Walker
“After thirty years of intensive research, we can now answer many of the questions posed earlier. The recycle rate of a human being is around sixteen hours. After sixteen hours of being awake, the brain begins to fail. Humans need more than seven hours of sleep each night to maintain cognitive performance. After ten days of just seven hours of sleep, the brain is as dysfunctional as it would be after going without sleep for twenty-four hours. Three full nights of recovery sleep (i.e., more nights than a weekend) are insufficient to restore performance back to normal levels after a week of short sleeping. Finally, the human mind cannot accurately sense how sleep-deprived it is when sleep-deprived.”
Matthew Walker, Why We Sleep: Unlocking the Power of Sleep and Dreams

Matthew Walker
“From this cascade comes a prediction: getting too little sleep across the adult life span will significantly raise your risk of developing Alzheimer’s disease. Precisely this relationship has now been reported in numerous epidemiological studies, including those individuals suffering from sleep disorders such as insomnia and sleep apnea.VIII Parenthetically, and unscientifically, I have always found it curious that Margaret Thatcher and Ronald Reagan—two heads of state that were very vocal, if not proud, about sleeping only four to five hours a night—both went on to develop the ruthless disease. The current US president, Donald Trump—also a vociferous proclaimer of sleeping just a few hours each night—may want to take note.”
Matthew Walker, Why We Sleep: Unlocking the Power of Sleep and Dreams
