Here's a link to an article on neurally mediated syncope. "Syncope" means fainting. This is obviously *not* what is going on here, but the mechanisms are similar. You can read about orthostatic intolerance, too.

This site provides a lot of detail but doesn't describe what goes in neurally mediated hypotension, where you don't pass out, and the effects can be delayed and long-lasting. It can feel like hypoglycemia because you aren't getting enough blood, period, to your brain. I used to feel dazed, weak, and foggy for hours after exercise.
Norepinephrine, the hormone that is supposed to signal the blood vessels to contract and raise blood pressure, is the same as the neurotransmitter norepinephrine that may be implicated in depression.
