Recommended Hours of Sleep Per Day

The recommended amount of sleep is dictated by developmental stages and physiological needs — it primarily depends on age.

The CDC recommends 7 or more hours for adults ages 18–60, while teenagers should aim for 8–10 hours. For younger children the requirements increase, with preschoolers needing 10–13 hours and toddlers needing 11–14, including naps. Newborns and infants need the most sleep, from 12–17 hours depending on age.

How long does the average person sleep per night?

According to recent data, Americans in all age ranges experience insufficient sleep and high schoolers are most likely to not sleep enough.

While children and adults experience insufficient rates of sleep at similar rates (35% and just over 36%), 77% of high schoolers report not sleeping enough.
