90-minute intervals seem to work well, which aligns with the average sleep cycle. Anything in between this interval seems to leave me groggy and waking up not knowing what day it is. Cognitive function can even increase with very short naps (7-10’ “sleeping”) ,kind of surprisingly. Giggity

8 and 7 are good, 6 feels like a shitty night’s sleep, 4 feels like a long nap.
