Which age group should sleep about 8-9 hours per night?

Sleep needs change with age, and adolescents have a typical target around 8–10 hours per night. The 8–9 hour range fits this group well because puberty brings a shift toward later bedtimes while still requiring enough sleep for brain development, learning, mood regulation, and growth. In practice, many adolescents struggle to get enough sleep due to early school start times and busy evenings, so aiming for about 8–9 hours helps support better attention and functioning. Newborns require much more sleep (roughly 14–17 hours), older adults often benefit from a bit less (around 7–8 hours), and adults generally aim for about 7–9 hours. Among the options, adolescence is the group for whom 8–9 hours is the most characteristic and appropriate target.
