Abstract

Non‐technical summary: One of the proposed functions of sleep is to conserve energy. We determined the amount of energy conserved by sleep in humans, how much more energy is expended when missing a night of sleep, and how much energy is conserved during recovery sleep. Findings support the hypothesis that a function of sleep is to conserve energy in humans. Sleep deprivation increased energy expenditure indicating that maintaining wakefulness under bed‐rest conditions is energetically costly. Recovery sleep after sleep deprivation reduced energy use compared to baseline sleep suggesting that human metabolic physiology has the capacity to make adjustments to respond to the energetic cost of sleep deprivation. The finding that sleep deprivation increases energy expenditure should not be interpreted that sleep deprivation is a safe or effective strategy for weight loss as other studies have shown that chronic sleep deprivation is associated with impaired cognition and weight gain.

  • When 24-hour energy expenditure was measured in a metabolic chamber, energy expenditure was increased with sleep restriction relative to habitual sleep.

    “However, when 24-hour energy expenditure was measured in a metabolic chamber, which provides a more confined environment, energy expenditure was increased with sleep restriction relative to habitual sleep.59,82,83”
  • Resting energy expenditure, as determined by indirect calorimetry, was lower in healthy volunteers during sleep compared to wakefulness.

    “Indeed, resting EE, as determined by indirect calorimetry, was lower in healthy volunteers during sleep compared to wakefulness.43”
  • Mean 24-hour plasma cortisol often remains unchanged by sleep deprivation, but circadian cortisol pattern changes.

    “Mean 24-h levels of plasma cortisol often remain unchanged by sleep deprivation,43,95,96,99,106,109,123 but the circadian cortisol-pattern changes, as described above.”
  • One night of total sleep deprivation increases energy expenditure during the night, but reduces next-day resting and postprandial energy expenditure by 5% and 20%, leading to positive energy balance.

    “Two groups found that one night of total sleep deprivation increased EE during the night, whereas the following day, resting and postprandial EE were reduced by 5% and 20%, respectively, overall leading to a positive energy balance43,100”
  • One night of total sleep deprivation in 7 healthy participants increased energy expenditure by 32% during the night of TSD and then decreased by 4% during the recovery night when compared to baseline.

    “One night of TSD in 7 healthy participants increased EE by 32% during the night of TSD and then decreased by 4% during the recovery night when compared to baseline [58].”

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.
