ACTH exhibits a circadian secretion rhythm, regulated by light and dark cycles.

The ACTH concentration reaches its peak upon waking and decreases throughout the day, reaching a minimum concentration around midnight.

Other factors such as pain, fever, and hypoglycemia also stimulate ACTH secretion.

ACTH secretion is used to evaluate the functionality of the hypothalamic-pituitary-adrenal axis.
