Cortisol, the stress hormone

Cortisol is fundamental for our body and may cause an ambulance if its values are too high or too low.

Cortisol is a steroid hormone produced by cells located on the zona fasciculata adrenal gland in response to the Adrenocorticotropic hormone ACTH.

Cortisol is often referred to as the “stress hormone” because it increases during psychophysical stressful situations, for example: after a prolonged and intense physical activity, surgery, sudden temperature changes or long periods without food.

During physical activity, cortisol levels increase only to stabilize during post workout recovery. This brief hormone spike strengthens the immune system, memory, it regulates appetite, sexual health, it stimulates weight loss, etc…
