What if scientists found a revolutionary new treatment that does the following:
Makes you live longer, enhances your memory, creativity, and attention, makes you look more attractive, keeps you slim, protects you from cancer and dementia, and it prevents colds, flu, and lowers risk of heart attacks, and diabetes. You’ll even feel happier, less depressed, and less anxious.
Sleep is a natural treatment that helps with all of those things.
Some other notes that I took from this summary
on the book below:
- Being awake for 19 hours is as cognitively impairing as being legally drunk.
- Driving after having slept less than 4 hours increases crash risk by 11.5x.
- Chronic sleep deficits are as damaging to attention as all-nighters – 6 nights of 4-hour sleep are equal to one all-nighter; 10 nights of 6-hour sleep are equal to the same. Performance progressively worsens with greater sleep deficit.
- Sleep is present in all animal species, even invertebrates. And bacteria that survive for longer than 24 hours have circadian-like rhythms. So despite its apparent drawbacks (vulnerability, “loss” of time), there must be must be something really important evolutionarily about sleep.
