Sleep as a Reset
- Sleep is the most effective way to reset brain and body health.
- It involves dramatic brainwave changes, with REM sleep showing 30% more activity than waking.
Sleep: The Proto-State?
- Dr. Walker suggests sleep may have predated wakefulness, not the other way around.
- Wakefulness may have emerged from sleep, making sleep the price we pay for being awake.
