How does the body keep cortisol levels in the blood right?
The body regulates cortisol levels in the blood using a negative feedback mechanism where the pituitary gland and adrenal glands communicate with each other. When cortisol levels are high, the pituitary gland reduces the production of corticotropin-releasing hormone (CRH) and adrenocorticotropic hormone (ACTH), which lowers cortisol levels.
