Sleep by age: the row that applies, and where eight sits
The CDC's nine age rows, the three panels behind them, and what eight hours means in each adult row — a floor at 18–60, a midpoint, a ceiling after 65.
Adults have three rows in this table, and the boundaries land at 60, 61 and 65. Pick the row that applies, then enter the hours you actually get — on average, not last night.
The comparison is against the published band, not against a diagnosis. Duration is one question and the CDC treats quality as a separate one — trouble falling asleep, repeated waking, and feeling tired even after enough hours are its own listed signs that the hours are not the whole story.
One table, three sources. That is why the bands do not tile perfectly, and why the adult rows disagree about what eight means.
| Age | Recommended daily sleep | Panel behind the row |
|---|---|---|
| 0–3 months | 14 –17 hours | National Sleep Foundation |
| 4–12 months | 12 –16 hours | AASM pediatric consensus |
| 1–2 years | 11 –14 hours | AASM pediatric consensus |
| 3–5 years | 10 –13 hours | AASM pediatric consensus |
| 6–12 years | 9 –12 hours | AASM pediatric consensus |
| 13–17 years | 8 –10 hours | AASM pediatric consensus |
| 18–60 years | 7 or more hours | AASM / Sleep Research Society |
| 61–64 years | 7 –9 hours | National Sleep Foundation |
| 65 years and older | 7 –8 hours | National Sleep Foundation |
Eight is not the floor of any of the three adult rows. Seven is. Eight appears inside the numbers the panels published — never as a figure either of them states as a requirement.
| Row | Published | Where eight sits |
|---|---|---|
| 18–60 years | 7 or more hours | above the floor, which is the only requirement in the row |
| 61–64 years | 7–9 hours | exactly the midpoint of the band |
| 65 years and older | 7–8 hours | the top of the band |
The consensus statement behind the 18–60 row is written for healthy adults in that range, and it says itself that individual variability in sleep need is influenced by genetic, behavioral, medical and environmental factors. The sleep foundation makes the same point from the other side: some people function well at the low end of a range and others need the upper limit.
Eight hours is the number everyone repeats, and it is not the floor of any adult row in the federal table. Seven is. That single fact decides whether a seven-hour night counts as a miss or a pass, and the answer moves again at 61 and at 65.
The lookup above returns the row that applies, the panel behind it, and — if you enter your hours — whether they fall inside the published band.
Three rows for adults, and three different jobs for the number eight
The table gives adults 18 to 60 a floor rather than a band: seven or more hours per night on a regular basis. It gives 61 to 64 a band of seven to nine hours, and 65 and older a band of seven to eight. In the first row, eight is simply above a floor. In the second it is the midpoint — seven plus nine, divided by two. In the third it is the ceiling.
None of that is a disagreement about sleep. It is what happens when one table is assembled from three reviews that asked slightly different questions, and the footnotes are what tell you which one you are reading.
What the comparison can and cannot say
- It is about a pattern, not a night. The consensus statement is written “on a regular basis”, and the CDC’s survey asks adults for an average 24-hour period. A single short night is not what those documents describe.
- Duration is one question. The CDC draws a line between duration and quality and lists its own signs of poor quality, so clearing the hours is not the same as sleeping well.
- It is not a diagnosis. The consensus statement is written for healthy adults aged 18 to 60 and says that individual variability is influenced by genetic, behavioral, medical and environmental factors. The sleep foundation makes the same point from the other side: some people function well at the low end of a range and others need every minute of the upper limit.
Where the rows come from
Each row of the CDC’s table carries a numbered footnote, and the footnotes point at three different documents rather than one. That is why the bands do not tile perfectly — the table’s school-age row stops at 12 while the sleep foundation’s own guidance for that group runs to 13 — and why the adult rows disagree about what eight means.
The figures here were last checked against the CDC’s page and the two consensus statements on 16 October 2026. The fuller account — where eight came from, what the survey data counts as short, and how to read your own row — is in How much sleep do adults need?.
Frequently asked questions
- Is eight hours of sleep the recommendation?
- Not as a requirement. In the adult rows of the federal table the only figure stated as a requirement is seven. Eight appears inside the bands the panels published — the midpoint of the 61-to-64 band, and the ceiling of the 65-and-older band — and it is not the floor of any adult row.
- What counts as short sleep?
- The CDC's own definition is self-reporting less than seven hours in a 24-hour period. Seven hours sits at the floor of the 18-to-60 recommendation rather than beneath it, which is why a seven-hour night is not by that definition a short one.
- Why do the age bands not line up across the table?
- Because one table is assembled from three sources. The 18-to-60 row comes from the 2015 joint consensus statement of the American Academy of Sleep Medicine and the Sleep Research Society; the 61-to-64 and 65-and-older rows come from the National Sleep Foundation; and every row from 4 months to 17 years comes from the AASM pediatric consensus statement. The bands are the ones those panels chose.
- Does hitting the hours mean I slept well?
- No. The CDC separates duration from quality, and lists trouble falling asleep, repeatedly waking during the night, and feeling sleepy or tired even after enough sleep as signs of poor quality. Its instruction for regular sleep problems is to talk to a healthcare provider; the common sleep disorders it names are insomnia, restless legs syndrome, narcolepsy and sleep apnea.
- How many adults fall short?
- In 2022 the share reporting less than seven hours ranged from 30 percent of adults in Vermont to 46 percent in Hawaii, and it was highest among men (37 percent), adults aged 45 to 64 (39 percent) and Native Hawaiian or Pacific Islander adults (49 percent). The national share did not change between 2013 and 2022. These are self-reported survey estimates, not measurements.
