   Why is the stress response important?

   • The stress response has an important evolutionary basis. It helped our ancestors, who faced numerous physical threats, to stay safe. In these times, the main threats faced were physical in nature and short-lived (such as predators or other environmental dangers). Today, our threats are less physical and more associated with our way of life.
