Younger people, particularly those under the ages of 16-20, have substantially higher sleep requirements than older adults. More specifically, they have a higher requirement of vital sleep stages (SWS and REM), which in general cannot be cut.

Moreover, light sleep, particularly the sleep spindles prominent in NREM2, has been suggested to play a role in brain development. <ref>Alex Chatburn, BA (Hons) (Psych), Scott Coussens, BSci (Hons), Kurt Lushington, PhD, Declan Kennedy, MD, Mathias Baumert, PhD, Mark Kohler, PhD,  Sleep Spindle Activity and Cognitive Performance in Healthy Children, ''Sleep'', Volume 36, Issue 2, 1 February 2013, Pages 237–243, <nowiki>https://doi.org/10.5665/sleep.2380</nowiki></ref> Cutting light sleep via polyphasic adaptation could do harm this process and impair cognitive development.
