During adolescence, total daily sleep time declines from about 10 hours to what range by the end?

Adolescents tend to shift toward later bedtimes due to changes in their internal clock, but early school start times keep wake times fixed. This mismatch reduces how much sleep they get each night, so total sleep declines as they move through puberty. By the end of adolescence, many people commonly sleep about 7–8 hours per night. This range reflects the trend from longer sleep in younger years to a shorter, more constrained nightly duration during teen years, and it aligns with observed patterns of teen sleep more than higher ranges. Keeping this in mind, a nightly 7–8 hours is the typical end-of-adolescence pattern.
