Quizplus · Accepted Answer

Diurnal variation in secretion occurs with glucocorticoids and is related to the sleep-awake cycle. It is a normal physiological process where the levels of glucocorticoids, such as cortisol, are highest in the morning and lowest at night. This pattern is regulated by the circadian rhythm and is important for maintaining normal bodily functions. While stress can affect cortisol secretion, it is not the only factor involved in the diurnal variation.
