Maybe people should just sleep 8 hours a night like they're supposed to.
We don't naturally sleep 8 hours a night. We naturally sleep for two blocks of 3-4 hours per day, which the lifestyle requirements of the modern world have forced to occur in a more-or-less continuous 7-8 hour block.
Pre-industrially, those two blocks would have an hour or two of waking time between them; modern research (mostly military) has found that splitting them apart further allows people to go with as little as 4-5 hours of sleep per 24 hour period with only minimal impact on performance.
