Abstract

Background Sleep disturbance is associated with inflammatory disease risk and all-cause mortality. Here, we assess global evidence linking sleep disturbance, sleep duration, and inflammation in adult humans. Methods A systematic search of English language publications was performed, with inclusion of primary research articles that characterized sleep disturbance and/or sleep duration or performed experimental sleep deprivation, and assessed inflammation by levels of circulating markers. Effect sizes (ES) and 95% confidence intervals (CI) were extracted and pooled using a random effect model. Results A total of 72 studies (n>50000) were analyzed with assessment of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor α (TNF). Sleep disturbance was associated with higher levels of CRP (ES 0.12; 95% CI 0.05 – 0.19) and IL-6 (ES 0.20; 95% CI 0.08 – 0.31). Shorter sleep duration, but not the extreme of short sleep, was associated with higher levels of CRP (ES 0.09; 95% CI 0.01 – 0.17) but not IL-6 (ES 0.03; 95% CI −0.09 – 0.14). The extreme of long sleep duration was associated with higher levels of CRP (ES 0.17; 95% CI 0.01 – 0.34) and IL-6 (ES 0.11; 95% CI 0.02 – 0.20). Neither sleep disturbances nor sleep duration was associated with TNF. Neither experimental sleep deprivation nor sleep restriction was associated with CRP, IL-6, or TNF. Some heterogeneity among studies was found, but no evidence of publication bias. Conclusions Sleep disturbance and long sleep duration, but not short sleep duration, are associated with increases in markers of systemic inflammation.

  • Disrupted sleep may activate inflammatory processes, such as elevations in IL-6 and CRP, according to observational and experimental studies.

    “That disrupted sleep may lead to activation of inflammatory processes (e.g., elevations in interleukin-6 [IL-6] and C-reactive protein [CRP]) has received substantial support from observational and experimental studies (Irwin et al., 2016; Irwin & Piber, 2018).”

    From Sleep and suicide: A systematic review and meta-analysis of longitudinal studies (2020) · cites this paper as Irwin et al., 2016

    The Results and Discussion report that sleep disturbance was associated with higher circulating IL-6 and CRP, supporting the observational part of the claim. The Discussion says experimental sleep loss activated cellular inflammatory pathways but did not raise circulating inflammatory markers; thus experimental evidence does not support the cited example of elevated IL-6 and CRP.

  • Elevation of pro-inflammatory cytokines is associated with sleep disruption.

    “their elevation is associated with both sleep disruption (Irwin et al., 2016)”

    From Physiological feelings (2019) · cites this paper as Irwin et al., 2016

  • Sleep has a restorative effect on the immune system, the endocrine system, facilitates recovery of the nervous system and metabolic cost of the waking state, and has an integral role in learning, memory and synaptic plasticity.

    “Sleep has been shown to have a restorative effect on the immune system, the endocrine system, facilitate the recovery of the nervous system and metabolic cost of the waking state and has an integral role in learning, memory and synaptic plasticity, all of which can impact both athletic recovery and performance.”

  • Sleep disturbances and short sleep duration are behavioural risk factors for inflammation and are associated with increased risk of illness and disease.

    “Sleep disturbances and short sleep duration are behavioural risk factors for inflammation, associated with increased risk of illness and disease, which can be modified to promote sleep health.”

    From Sleep and Nutrition Interactions: Implications for Athletes (2019) · cites this paper as [18]

  • Sleep disturbance and extremes of sleep duration affect risk factors of inflammatory disease and contribute to all-cause mortality.

    “Research has demonstrated that sleep disturbance (i.e. insomnia) and extremes of sleep durations affect risk factors of inflammatory disease and contribute to all-cause mortality [18,22].”

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.
