Sleep changes across later life, but aging does not eliminate the need for adequate sleep. The available evidence spans U.S. household surveys, time diaries, worldwide pooled studies, and randomized treatment trials, so percentages and hours must be read with their different definitions and populations in mind.
Key Sleep and Aging Statistics
The following highlights summarize distinct measures from the U.S. and international evidence:
- In 2024, 27.2% of U.S. adults ages 65 and older reported fewer than 7 hours of sleep in a 24-hour period.
- In 2024, 34.5% of U.S. adults ages 50–64 reported fewer than 7 hours of sleep.
- In 2024, 63.5% of U.S. adults ages 65 and older said they woke feeling well-rested most days or every day.
- In 2024, 21.7% of U.S. adults ages 65 and older reported trouble staying asleep most days or every day.
- In 2024, 12.8% of U.S. adults ages 65 and older reported trouble falling asleep most days or every day.
- A 2025 meta-analysis estimated poor sleep quality in 50% of adults ages 60 and older worldwide.
- The same review covered 52 cross-sectional studies and 24,217 adults ages 60 and older.
- The worldwide review estimated obstructive sleep apnea in 46.0% of community-dwelling adults ages 60 and older.
- The worldwide review estimated insomnia in 29.0% of community-dwelling adults ages 60 and older.
- It estimated excessive daytime sleepiness in 19.0% of community-dwelling adults ages 60 and older.
- The worldwide sleep-problem review pooled 995,544 participants from 252 studies in 36 countries.
- A DSM-based review estimated insomnia disorder prevalence at 19.6% among older persons.
- That DSM review included 18,270 participants across 16 studies.
- BLS time diaries recorded 9.76 hours of sleep per day for U.S. adults ages 65–74 in 2024.
- BLS time diaries recorded 10.13 hours per day for U.S. adults ages 75 and older in 2024.
- A treatment network meta-analysis included 53 randomized controlled trials involving 6,832 adults older than 65.

Sleep and Aging Statistics: Duration Across Older Age Groups
The National Institute on Aging says older adults generally need about 7 to 9 hours of sleep per night, the same recommended range as other adults. This is clinical guidance, not a prevalence estimate, and it should not be confused with a measured population average. National Institute on Aging, “Sleep and Older Adults”
In the 2024 U.S. National Health Interview Survey, short sleep meant reporting 0–6 whole hours on average in a 24-hour period. The age pattern was not a simple steady increase:
| U.S. population, 2024 | Reporting fewer than 7 hours | Measure |
|---|---|---|
| Ages 18–34 | 27.2% | Self-reported NHIS survey |
| Ages 35–49 | 33.4% | Self-reported NHIS survey |
| Ages 50–64 | 34.5% | Self-reported NHIS survey |
| Ages 65+ | 27.2% | Self-reported NHIS survey |
Source: CDC/NCHS, “Short Sleep Duration and Sleep Difficulties Among Adults: United States, 2024”. These are nationally representative estimates for the U.S. civilian noninstitutionalized population and are self-reported.
Other 2024 NHIS comparisons show that short sleep affected 30.6% of men and 30.4% of women. By survey-defined race and ethnicity categories, the figures were 40.2% for Black non-Hispanic adults, 27.9% for Asian non-Hispanic adults, 28.9% for White non-Hispanic adults, and 29.0% for Hispanic adults.
Sleep and Aging Data on Quality and Feeling Rested
Duration alone does not describe whether sleep feels restorative. In 2024, 63.5% of U.S. adults ages 65 and older said they woke feeling well-rested most days or every day, compared with 54.5% of adults ages 50–64, 50.1% of adults ages 35–49, and 52.2% of adults ages 18–34. CDC/NCHS, “Short Sleep Duration and Sleep Difficulties Among Adults: United States, 2024”
| U.S. population, 2024 | Woke well-rested most days or every day |
|---|---|
| Ages 18–34 | 52.2% |
| Ages 35–49 | 50.1% |
| Ages 50–64 | 54.5% |
| Ages 65+ | 63.5% |
| All adults | 54.8% |
The same survey found that 58.2% of men and 51.7% of women reported feeling well-rested. The corresponding figures were 61.5% for Asian non-Hispanic adults, 51.4% for Black non-Hispanic adults, 54.3% for White non-Hispanic adults, and 57.6% for Hispanic adults.
A 2025 systematic review and meta-analysis estimated poor sleep quality at 50% among adults ages 60 and older worldwide. It synthesized 52 cross-sectional studies covering 24,217 adults through May 22, 2024, but heterogeneity was very high, with I²=99.60%; 48 studies were rated good quality and 4 moderate quality. Worldwide prevalence of sleep problems in community-dwelling older adults
Country estimates in that PSQI-based review ranged from 14% in China to 96% in Malaysia. These figures reflect included cross-sectional studies, differing settings, and different cutoffs, rather than one standardized global surveillance series.
Insomnia and Sleep Difficulties Among Older Adults
The 2024 NHIS separates difficulty falling asleep from difficulty staying asleep and asks whether each occurred most days or every day in the prior 30 days. These categories are self-reported frequency measures, not DSM insomnia diagnoses, and they should not be combined as mutually exclusive groups. CDC/NCHS, “Short Sleep Duration and Sleep Difficulties Among Adults: United States, 2024”
- Trouble falling asleep affected 12.8% of U.S. adults ages 65 and older, 14.5% of adults ages 50–64, 15.4% of adults ages 35–49, and 18.3% of adults ages 18–34 in 2024.
- Overall, 15.4% of U.S. adults had trouble falling asleep most days or every day in 2024; women reported this more often than men, 18.5% versus 12.2%.
- Trouble staying asleep affected 21.7% of adults ages 65 and older, 22.3% of adults ages 50–64, 16.9% of adults ages 35–49, and 12.7% of adults ages 18–34.
- Overall, 18.1% of U.S. adults had trouble staying asleep most days or every day in 2024; the figures were 21.4% for women and 14.6% for men.
A narrower DSM-based systematic review and meta-analysis estimated insomnia disorder prevalence at 19.6% among older persons, with a 95% confidence interval of 12.3%–28.3%. The estimate came from 16 studies published before June 28, 2023, included 18,270 participants, and had substantial heterogeneity, publication bias, and very low certainty. Epidemiology of insomnia disorder in older persons
Across eight studies in that review, mean participant age ranged from 65.9 to 83.1 years. The male-to-female ratio was 0.89 across the 12 studies that reported sex composition; this describes study composition, not sex-specific risk.
Sleep Apnea and Other Sleep Problems in Aging Populations
A worldwide meta-analysis of community-dwelling older adults defined sleep problems across varied diagnostic methods, instruments, and settings. Covering studies from 1988–2023, it pooled 995,544 participants from 252 studies in 36 countries. Worldwide prevalence of sleep problems in community-dwelling older adults
| Sleep problem | Pooled estimate | Population and period |
|---|---|---|
| Obstructive sleep apnea | 46.0% | Community-dwelling adults 60+, studies 1988–2023 |
| Poor sleep quality | 40.0% | Community-dwelling adults 60+, studies 1988–2023 |
| Other sleep problems | 37.0% | Community-dwelling adults 60+, studies 1988–2023 |
| Insomnia | 29.0% | Community-dwelling adults 60+, studies 1988–2023 |
| Excessive daytime sleepiness | 19.0% | Community-dwelling adults 60+, studies 1988–2023 |
These pooled estimates are not interchangeable with the separate 50% PSQI-only poor-sleep-quality estimate or the 19.6% DSM-specific insomnia estimate. The review’s composite categories, self-reports, diagnostic methods, and underlying definitions varied across studies, so the percentages describe broad evidence summaries rather than one uniform measurement system.
Sleep and Aging Treatment Evidence and Time-Use Measures
Treatment research describes what was studied in trials, not how many older adults receive treatment or which option is universally recommended. A network meta-analysis of insomnia treatments in adults older than 65 included 53 randomized controlled trials searched through May 25, 2019, with 6,832 participants whose average age was 75 years. Efficacy, acceptability, and tolerability of all available treatments for insomnia in the elderly
Of those 53 trials, 43 examined the efficacy of one or more drugs. Trial counts indicate the scope of the evidence base; interventions and outcomes differed, so they are not population treatment-uptake rates.
BLS American Time Use Survey diaries provide a different view of sleep: time spent in the primary activity of sleeping. In 2024, respondents ages 65–74 averaged 9.76 hours per day and respondents ages 75 and older averaged 10.13 hours per day. BLS, “American Time Use Survey News Release — 2024 A01 Results”
| U.S. population, 2024 ATUS | Sleep per day |
|---|---|
| Men ages 65–74 | 9.48 hours |
| Women ages 65–74 | 10.22 hours |
| Men ages 75+ | 9.85 hours |
| Women ages 75+ | 10.42 hours |
ATUS is a diary-based primary-activity estimate, not actigraphy, a clinical sleep measure, or the NHIS question about average sleep in a 24-hour period. The differing methods explain why these hours should be interpreted separately from the short-sleep percentages.
