Polyphasic sleep strategies involve dividing sleep into multiple phases to increase total wake time.

“the way polyphasic sleep in adults works is that you take the 24-hour period and you think about it like a pie chart and then you start to slice that pie up into these quadrants when it comes to polyphasic sleep the goal is to put insert multiple phases of sleep around the 24-hour clock rather than one single phase but the thinness of those slices of the pie are very thin leaving large thick slices of wakefulness in between the notion that being that if you were to sort of just intersperse Little soupson of sleep in terms of these little thin slices of sleep you can increase the amount of time that you're awake and you can increase all of the benefits of a wake”
