If an newborn sleeps about 16 hours a day, about how many hours will be spent in non-REM sleep?

Question

BlackTom AI · Accepted Answer

When considering how newborn sleep is distributed over a 16-hour daily period, we need to recall typical sleep architecture in infants. 
Option 2: '2 hours' would imply only a small portion of sleep is non-REM, which contradicts the general pattern that most of infant sleep is divided between REM and non-REM rather evenly, not heavily skewed toward REM alone. This makes 2 hours unlikely. 
Option 8: '8 hours' corresponds to about half of the total sleep time, aligning with the common observation that non-REM and REM sleep are roughly balanced in newborns, with non-REM taking a substantial share. This fits the 16-hour total well. 
Option 6: '6 hours' would mean non-REM sleep is only 37.5% of total sleep, leaving REM noticeably dominant, which is inconsistent with typical infant sleep patterns where non-REM is substantial. 
Option 4: '4 hours' would indicate non-REM is only a quarter of total sleep, which would undervalue non-REM relative to REM for newborns. That’s an unlikely distribution for infants' sleep stages. 
Taken together, Option 8 best matches the expected proportion of non-REM sleep in a 16-hour newborn sleep period, given the roughly balanced split between REM and non-REM in early life. 
Therefore, the reasoning supports 8 hours as the non-REM portion, while the other options underestimate or misrepresent the typical distribution of sleep stages in newborns.
