Abstract

Sleep patterns change with aging, independent of other factors, and include advanced sleep timing, shortened nocturnal sleep duration, increased frequency of daytime naps, increased number of nocturnal awakenings and time spent awake during the night, and decreased slow wave sleep. Most of these changes seem to occur between young and middle adulthood; sleep parameters remain largely unchanged among healthy older adults. The circadian system and sleep homeostatic mechanisms become less robust with normal aging. The amount and pattern of sleep-related hormone secretion change as well. The causes of sleep disturbances in older adults are multifactorial.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Sleep need decreases with older age.

    “An important consideration in determining accumulated sleep debt is that sleep need itself decreases with older age.”

    From Sleep, testosterone and cortisol balance, and ageing men (2022) · cites this paper as [18]

    The Sleep duration section reports that total sleep time generally decreases with age, but says the decline tends to plateau after about age 60. Changes in sleep homeostasis reports reduced sleep pressure with aging. Neither section establishes that sleep need itself decreases; sleeping less is not necessarily needing less sleep. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The proportion of slow wave sleep and REM sleep decreases while the proportion of stage 1 and 2 sleep increases before age 60, but is stable thereafter.

    “Sleep architecture changes analogously over this age period: the proportion of SWS and REM sleep decreases while the proportion of stage 1 and 2 sleep increases before age 60, but is stable thereafter.”

    From Sleep, testosterone and cortisol balance, and ageing men (2022) · cites this paper as [18]

    The Sleep stages section reports the stated age-related shifts and says they were not significant among healthy adults over 60. But it also reports a small decline in REM sleep through age 75 in another meta-analysis, so the unqualified statement that all four proportions are stable after 60 overstates the source. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Sleep need decreases with age, but only up to 60 years, after which sleep need remains stable.

    “This is because sleep need decreases with age, but only up to 60 years, after which sleep need remains stable.”

    From Sleep, testosterone and cortisol balance, and ageing men (2022) · cites this paper as [18]

    The Sleep duration section reports that total sleep time decreases with age and plateaus after about 60, particularly among healthy older adults. That supports the age pattern, but the paper describes time slept, not a decrease in how much sleep people need. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Total sleep time decreases by 10-12 min for each decade of life from age 20 to 60 years, but does not change thereafter.

    “Meta-analyses of cross-sectional studies of healthy adults show that total sleep time decreases by 10–12 min for each decade of life from age 20 to 60 years, but does not change thereafter [18].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
