Awakening not associated with an increased rate of cortisol secretion | Proceedings of the Royal Society B: Biological Sciences Cortisol is released upon activation of the hypothalamic–pituitary–adrenal axis, varies across the day, possesses an underlying diurnal rhythm and is responsive to stressors. The endogenous circadian peak of cortisol occurs in the morning, and increases ...

🚨 Fresh from the press! "Awakening not associated with an increased rate of cortisol secretion", where together with @tjupton.bsky.social and members of the #ULTRADIAN consortium we call for caution when using the #CAR in human studies. royalsocietypublishing.org/doi/10.1098/...

Awakening not associated with an increased rate of cortisol secretion

Extremely pleased to announce our analysis out today with @ederzavala.bsky.social and other members of #ULTRADIAN
