Automatic summary · not editorially reviewedThe description states that ghrelin rises in the first half of a normal night and falls toward morning, that this rise is smaller on nights spent awake, and that higher ghrelin at sleep onset has been correlated with a higher growth hormone peak. [1]
During normal sleep, ghrelin secretion rises in the first half of the night and declines toward morning. [1]
The nighttime ghrelin rise is diminished on nights spent awake, which the description links more strongly to sleeping itself than to the body clock. [1]
Higher ghrelin at sleep onset has been correlated with a higher growth hormone peak, suggesting ghrelin may facilitate deep non-REM sleep. [1]
Ghrelin rise during normal sleep
According to the description, ghrelin secretion rises in the first half of the night during normal sleep and declines toward morning. The description presents this as a change in nighttime secretion, not as a finding about daytime levels or about hunger itself. [1]
Smaller rise on nights spent awake
The description says the nighttime ghrelin rise is diminished on nights spent awake. Because this rise is smaller then, the description states the nighttime increase is more strongly linked to the act of sleeping itself than to the internal body clock. This is a described association, not proof of cause. [1]
Correlation with growth hormone peak
The description reports an observed correlation: higher ghrelin levels at the onset of sleep correspond to a higher peak in growth hormone secretion. It says this suggests ghrelin may facilitate deep non-REM sleep, described as the deepest sleep stage. The wording is suggestive, so this remains a possible role rather than an established effect. [1]
