In brief: Stress hormone

Cortisol is a naturally occurring hormone secreted everyday.
It has multiple roles. It is described as a stress hormone, secreted at higher levels during physical stresses. It's a steroid class hormone. So too much of it, whether your body is secreting it in appropriately or you are ingesting it, can cause sleep disturbances.
