How stress affects us
The stress response in the body, often referred to as the “fight/flight/freeze” response, is a physical response to a stressor. Stress is often in response to a person’s perceived ability to cope with a situation. This physical response shuts down many systems in the body eg digestion, and reproduction, and it heightens others. For example, the immune response is put on high alert, in readiness to deal with an injury, the heart/breathing rate and blood pressure increase, glucose is released into the blood, and all these automatic responses, prepare the body physically and mentally to respond to the stressor, eg run away or fight.
