Strong emotions such as fear or anger typically are associated with a stress response.
Hormones play the same role in both emotion and stress.
The initial hormonal response involves the release of epinephrine and norepinephrine, triggered by sympathetic nervous system activation.
This produces a state of arousal and alertness.
Physiological changes include pupil dilation; increased heart rate, respiration, and blood pressure; increased blood sugar; and slowing of digestive processes.
If the source of stress and strong emotion is not ended, the HPA axis may be activated.
In this case, the hypothalamus will send signals to the pituitary gland.
The pituitary gland will, in turn, signal the adrenal cortex to release cortisol and other stress hormones.
Cortisol further elevates blood sugar and protects the body from inflammation.
Although useful in the short term, continued elevation of cortisol can contribute to hypertension, immune disorders, weight gain, other physical ailments, and emotional problems.
