Stress hormones
Stress hormones are substances such as cortisol and adrenaline that help the body mobilize energy when faced with a challenge or threat.
Definition
During the stress response, the body activates biological systems that increase its readiness to act. Adrenaline supports rapid mobilization, and cortisol helps regulate energy availability and the body's reactions over time. Short-term stress can be adaptive, but chronic arousal can burden sleep, immunity, mood and cognitive functioning.

Common misunderstanding
It is a mistake to demonize cortisol as something exclusively bad. Stress hormones are needed, but the problem is lack of regeneration and chronic overload.
