Your stress response is the collection of physiological changes that occur when you face a perceived threat—when you face situations where you feel the demands outweigh your resources to successfully cope. (These situations are known as stressors.)
When your stress response is triggered, a series of changes occur within your body. They include:
- A quickening of your pulse
- A burst of adrenaline
- Redirection of blood away from extremities and instead to major organs
- The release of cortisol and other hormones, which bring other short- and long-term changes.
