Eight subjects, frequent sampling through an indwelling catheter so as not to wake them, and electroencephalographic staging of sleep. The pulse appeared reliably in the first slow-wave period and recurred in smaller form with later ones. Shifting sleep to the daytime shifted the pulse, showing the link was to sleep rather than to the clock.
It was among the first demonstrations that a hormone was gated by sleep stage.
Pharmacological enhancement of slow-wave sleep increases the pulse; suppression reduces it. The releasing hormone itself promotes slow-wave sleep in some studies, suggesting a shared hypothalamic mechanism. With ageing, slow-wave sleep and the nocturnal pulse diminish in parallel, and the proportion of daily secretion occurring in sleep falls. These are correlations with a plausible mechanism, not fully resolved causation.
The Tesamorelin pages on this site cite the sleep literature for the releasing-hormone analogue.
Because the timing of secretion is part of the established physiology of the hormone in the pack. This page describes it; it recommends nothing.
