Stress responses in us today often developed over many years and are inherited. For example, in response to stress, the pituitary gland and other systems within the body release hormones and trigger other responses to muster the body's defenses. Endorphins and other recently discovered morphine-like substances from the brain are part of a chemical cascade which is activated in response to physical and emotional stress. These chemicals also signal the brain to experience pleasure and provide relief from pain. Endorphins not only serve to diminish pain and anxiety, they also have wide spread effects on other functions and hormones.
Endorphins play a role in regulating temperature, intestinal function, and appetite.
They also moderate the effects of sexual and growth hormones and thyroid function, as well as play a role in the stress-relieving effect of exercise.
