People who suffer from chronic exhausting levels-- and who haven't learned how to do certain things to mitigate this -- are subjecting themselves to a literal overdose of extremely powerful hormones (usually referred to as "stress hormones") that are normally only intended for very brief periods of time in emergency situations. This is sometimes known as the "fight or flight response." Subjecting the body to this response on a constant basis is not a good thing. The way the body triggers these hormones is through what medical professionals called the parasympathetic response. And while some forms of tension are actually good for us, it is generally the rule that long-term exposure to stress has nothing to recommend it in the least. Recent studies have shown that people put under constant tension tend not to be able to learn things the same way that people who aren't constantly being bombarded by these hormones can learn. For the most part, the human body has evolved to the point where it can handle around a half minute of exposure to stress hormones with no serious side effects. Anything longer than that, though, and long-term issues can begin to develop. This is a direct result of our inability to escape the fight or flight response. We, as thinking creatures, evolved with certain faculties that enabled us to know when to stand and fight or when to get up and flee. In prehistoric times, we ran from a predator cat such as a saber tooth and the stress response would soon be over. However, in this day and age, we are bombarded with at seemingly every point. We have bosses who just won't let up or we are stuck in huge traffic jams that never seem to end. |
