Then the moment ends. The danger passes. Your body begins to change again. In the secondary, or resistant, stage of stress, your body beings to calm down and compose itself after all of the furore caused by the release of so many chemicals. The resistance stage is usually reached when whatever caused the alarm is identified and dealt with. And then, if whatever caused the initial stress is resolved, all of the reactions disappear, and everything is once again in order within the body's complex response system.
If whatever caused the initial stress continues, however, the body's ability to adapt to the stress becomes exhausted. It shuts down.
