See the below image for the Stress and nervous system explained diagram. This causes increased heart rate, blood pressure rises, and our bodies experience all of the intense physiological symptoms of stress. These two parts of the nervous system are the cornerstones of the stress response in the body and mind. The sympathetic nervous system tells us to go” and aids in the fight or flight” response.
How Stress and the Nervous System Are Linked When we are confronted with a stressful experience, the amygdala part of the brain sends a distress signal to the hypothalamus, which activates the nervous system and adrenal glands. These glands respond by pumping adrenaline into the bloodstream.
Our sympathetic nervous system has a direct role in our physical response to stress and generates what is known as our fight or flight response. This is a natural evolutionary response that was designed to protect us from danger by encouraging us to flee the danger or fight – fight or flight.
