Sleep health statistics show that insufficient sleep and sleep difficulties affect people across the life span. In 2024, 30.5% of U.S. adults slept less than 7 hours on average in a 24-hour period, while 54.8% woke feeling well-rested most days or every day. Among high school students, 24% reached at least 8 hours on an average school night in 2025.

Adult sleep duration and short sleep
The CDC’s Short Sleep Duration and Sleep Difficulties Among Adults: United States, 2024 reports that 30.5% of U.S. adults slept less than 7 hours on average in a 24-hour period in 2024. The measure describes average sleep duration, so it is distinct from a question about whether someone felt rested or had difficulty sleeping.
The 2024 adult estimate was similar for men and women: 30.6% of adult men and 30.4% of adult women slept less than 7 hours. The same CDC report found a larger difference across the usable age groups: 33.4% of adults ages 35–49 and 34.5% of adults ages 50–64 had short sleep, compared with 27.2% of adults ages 65 and older.
The racial and ethnic estimates also varied. In 2024, short sleep affected 40.2% of non-Hispanic Black adults, 28.9% of non-Hispanic White adults, 29.0% of Hispanic adults, and 27.9% of non-Hispanic Asian adults. These are U.S. population estimates for the measurement year; they do not describe an individual’s sleep need or diagnose a sleep disorder.

Feeling rested after sleep
Sleep duration and perceived restfulness are related but different measures. In 2024, 54.8% of U.S. adults reported waking feeling well-rested most days or every day, meaning the corresponding share did not report that level of restfulness on most or every day.
Men were more likely than women to report feeling well-rested most days or every day: the figures were 58.2% for men and 51.7% for women. Restfulness also differed by age. The reported percentages were 50.1% among adults ages 35–49, 54.5% among adults ages 50–64, and 63.5% among adults ages 65 and older.
The 2024 CDC estimates by race and ethnicity were 61.5% for non-Hispanic Asian adults, 51.4% for non-Hispanic Black adults, 54.3% for non-Hispanic White adults, and 57.6% for Hispanic adults. These results measure reported waking restfulness, not the number of hours slept.
Trouble falling or staying asleep
In the same 2024 CDC adult report, 15.4% of U.S. adults had trouble falling asleep most days or every day. The percentage was 12.2% among adult men and 18.5% among adult women. By age, the reported figures were 15.4% for adults ages 35–49, 14.5% for adults ages 50–64, and 12.8% for adults ages 65 and older.
Trouble staying asleep was more commonly reported than trouble falling asleep overall: 18.1% of adults had trouble staying asleep most days or every day in 2024. The figures were 14.6% for men and 21.4% for women. Among the reported age groups, 16.9% of adults ages 35–49, 22.3% of adults ages 50–64, and 21.7% of adults ages 65 and older had trouble staying asleep most days or every day.
| U.S. adult group, 2024 | Trouble falling asleep | Trouble staying asleep |
|---|---|---|
| All adults | 15.4% | 18.1% |
| Men | 12.2% | 14.6% |
| Women | 18.5% | 21.4% |
| Ages 35–49 | 15.4% | 16.9% |
| Ages 50–64 | 14.5% | 22.3% |
| Ages 65 and older | 12.8% | 21.7% |
By race and ethnicity, trouble falling asleep affected 9.0% of non-Hispanic Asian adults, 15.5% of non-Hispanic Black adults, 16.1% of non-Hispanic White adults, and 14.1% of Hispanic adults. Trouble staying asleep affected 9.2%, 16.7%, 20.7%, and 12.5% of those groups, respectively. The source wording is “most days or every day,” so these figures should not be read as lifetime prevalence.
State and county differences
The CDC’s FastStats: Sleep in Adults reports an age-adjusted percentage of 36.8% of adults reporting insufficient sleep in the 2022 Behavioral Risk Factor Surveillance System. This is a different measure and year from the 2024 short-sleep estimate above, so the figures should not be treated as a direct year-to-year trend.
In the 2022 BRFSS, the state-level age-adjusted percentage ranged from 30.0% in Vermont to 45.9% in Hawaii. The range describes reported insufficient sleep across states; it does not establish why the percentages differed.
The FastStats page also presents CDC model-based county estimates for 2020. Those estimates ranged from 23.8% in Boulder County, Colorado, to 48.4% in Greene County, Alabama. Because these are model-based estimates from 2020, they should be kept separate from the 2022 survey results and the 2024 national estimates.
High school sleep benchmarks
The CDC’s Youth Risk Behavior Surveillance System reports how many U.S. high school students got at least 8 hours of sleep on an average school night. In 2025, 24% met that benchmark. The comparable share was 27% in 2015 and 22% in 2019, providing three measurement points rather than a continuous annual series.
Among students measured in 2025, 26% of male students and 22% of female students got at least 8 hours on an average school night. The percentage was 31% among ninth-grade students and 20% among twelfth-grade students.
One reported racial or ethnic group estimate was 49% among American Indian or Alaska Native students in 2025. That estimate is presented here exactly as reported by the source and should not be generalized to all students or compared with unreported groups.
| U.S. high school students | At least 8 hours on an average school night |
|---|---|
| 2015 | 27% |
| 2019 | 22% |
| 2025 | 24% |
| Male students, 2025 | 26% |
| Female students, 2025 | 22% |
| Ninth grade, 2025 | 31% |
| Twelfth grade, 2025 | 20% |

Children’s routines and daytime tiredness
For younger children, regular routines and daytime tiredness provide two different views of sleep health. The CDC’s Sleep Routines and Tiredness Among Children Ages 2–17 Years: United States, 2024 reports that 85.6% of U.S. children ages 2–17 had a regular bedtime most days or every day in 2024.
The reported percentage was 86.1% for girls ages 2–17 and 77.5% for children ages 14–17. Among children ages 2–17 with a disability, 79.6% had a regular bedtime most days or every day. The figure was 88.0% among non-Hispanic Asian children ages 2–17 and 78.6% among children in families below 100% of the federal poverty level.
Daytime tiredness was less commonly reported overall than a regular bedtime: 8.1% of children ages 2–17 complained of being tired during the day most days or every day in 2024. The percentage was 14.6% among children ages 14–17, 22.0% among children ages 2–17 with a disability, and 4.7% among non-Hispanic Asian children ages 2–17.
These child statistics describe reported routines and complaints during 2024. A regular bedtime is not the same as a measured sleep duration, and daytime tiredness is not itself a diagnosis. Keeping those distinctions visible helps place adult, adolescent, and child sleep statistics in their proper context.
