Again I have tried all I can think of to get my answer. Ask.com Google, search function on CF....
However, I have not recieved a no BS conclusion. Basically what I have been able to deduce is that it is how our body reacts to stimulus from outside factors ie. sickness, work, stress. Well that is cool and nice but what the heck does that mean? Why is it important and why should I care? What is the benefit to me and how can I maximize my exposure?

I have seen it in a number of posts and just trying to be educated about it.

Thanks

PS. Before I post I generally spend a lot of time trying to answer my own questions before I seek outside help.

The endocrine system regulates homeostasis. It is a complex process, mainly involving hormones and positive/negative feedback to keep your body in tune. Basically, when stimulus X is applied (either internally- an infection, some organ going out of whack, etc- or externally- injuries, stress etc-) the endocrine system produces and releases hormones into your bloodstream, switching on and off cell/other system processes, in turn changing your body's internal makeup to a small degree (and hopefully overcoming the obstacle of the stimulus).

I am a little rusty on my bio, however, so sorry for vagueness/minor discrepancies...

Not that I have an intelligent answer to this, I just think it's amazing to know what I don't know until someone else asks. Thanks for the question (and answers!). :-)

Skylar, that's an excellent explanation.

I would only add that the nervous and endocrine systems work together to maintain homeostasis, but along different time frames. The nervous system is the first response team. Input/output often occurs faster than you can think, and when the stimulus is removed you return to pre-input status very quickly. The endocrine system also reacts, but slower, and its effects last for hours due to the release of hormones into the bloodstream. They take a while to filter back out.

For example, almost getting into a car accident. Your nervous system reacts immediately and reflexively, hopefully in time for you to avoid danger. At the same time, the endocrine system releases adrenaline, which is why a half hour later you're safe in your house but you still feel twitchy and jacked up.

From a practical point of view, avoiding situations where you're placed in stress w/o a physical outlet will help long term with blood pressure and other health problems. Feeling the stress and anticipation of a heavy squat, or Fight Gone Bad, AND THEN taking all your aggression out on the exercise promotes favorable hormone release and its consequent use by the body. Hormones are extremely powerful and if we do what we can to control/influence their release into the bloodstream, it will have a broad range of healthful effects.
