Role of Sleep and Sleep Loss in Hormonal Release and Metabolism

Abstract

Compared to a few decades ago, adults, as well as children, sleep less. Sleeping as little as possible is often seen as an admirable behavior in contemporary society. However, sleep plays a major role in neuroendocrine function and glucose metabolism. Evidence that the curtailment of sleep duration may have adverse health effects has emerged in the past 10 years. Accumulating evidence from both epidemiologic studies and well-controlled laboratory studies indicates that chronic partial sleep loss may increase the risk of obesity and weight gain. The present chapter reviews epidemiologic studies in adults and children and laboratory studies in young adults indicating that sleep restriction results in metabolic and endocrine alterations, including decreased glucose tolerance, decreased insulin sensitivity, increased evening concentrations of cortisol, increased levels of ghrelin, decreased levels of leptin and increased hunger and appetite. Altogether, the evidence points to a possible role of decreased sleep duration in the current epidemic of obesity. Bedtime extension in short sleepers should be explored as a novel behavioral intervention that may prevent weight gain or facilitate weight loss. Avoiding sleep deprivation may help to prevent the development of obesity, particularly in children.

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

  • Well-controlled laboratory studies in healthy adults have shown that repeated partial sleep restriction adversely affects systemic insulin sensitivity and glucose tolerance.

    “well-controlled laboratory studies in healthy adults have shown that repeated partial sleep restriction has adverse effects on systemic insulin sensitivity and glucose tolerance”
  • The finding identifies a molecular mechanism that may be involved in the reduction in total body insulin sensitivity observed in multiple laboratory studies of partial sleep deprivation.

    “To our knowledge, this finding identifies for the first time a molecular mechanism that may be involved in the reduction in total body insulin sensitivity consistently observed in multiple laboratory studies of partial sleep deprivation in healthy adults (11–17), as well as in the participants of our study.”
  • Insufficient sleep decreases plasma leptin levels, increases plasma ghrelin and cortisol levels, alters glucose homeostasis, and activates the orexin system, all of which affect appetite control.

    “Recent studies indicate that insufficient sleep decreases plasma leptin levels, increases plasma ghrelin and cortisol levels, alters glucose homeostasis and activates the orexin system, all of which affect appetite control [104].”

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.
