I would highly recommend "Why We Sleep" by Matthew Walker to get academic insight to latest research related to sleep and basic understanding what sleep is. There is a good touch on how other species sleep; and why having a nap during a day is beneficial in improving intellectual and physical capacities!

Sleep health benefits are definitely underrated in modern society..

Based on my understanding of the topic I sympathise the research narrative to move to polyphasic sleep cycle to COPE with sleep disorders I do not believe it is adequate sleeping routine to any healthy individual and doing so can be harmful to health!

And from personal note as a parent raising second infant I can confirm that having segmented night sleep over long periods of time is most de-humanizing experience with real mental threads.
