Why do we stay up so late, when we are so tired? On one hand, there are probably as many individual answers as there are insomniacs. But on the other hand, it could be simply adrenaline addiction. Physiologically speaking, there is a potential payoff to staying up late, if we wait for that time of night when we feel so tired, yet so wired... it can finally give way to a mellow feeling (not unlike being "high" on a drug).

I do know this. When evening comes, the epinephrine or adrenaline levels start to drop off, while the melatonin and seratonin increase... making us feel sleepy, but if you stay up beyond sleepy you get a second wind, of sorts, which is the body kicking in adrenaline to keep you going... since you insist on staying up... here you go, the payoff! Now you have a melatonin, serotonin, epinephrine cocktail of sorts!

Hmmm... which makes you wonder? What does adrenaline do to give you that rush? For one thing, it releases sugar into the bloodstream. Have you ever wondered why people who are withdrawing from addiction to heroin or alcohol crave sugar like crazy? Well, don't our brains use sugar (glucose) as fuel?

And while we're at it... what about the possible connection between insomnia and parasites. Could it be that parasites have adapted to their environment (US!) so as to make us want to stay up? Perhaps by making us crave sugar, or adrenaline? Anyway, it makes you wonder... a tired person with an equally tired immune system would make for an almost perfect environment for parasites to exist virtually undisturbed, without quite killing the host. I know it sounds like a Sci-Fi plot, "the Parasite Zombies" or something, but It makes you think when you consider that there is a fungal parasite, for example, that infects beetles in the tropical rain forest, and as it grows, it gives them tunnel vision, until they desperately climb toward the light.... higher and higher into the jungle canopy... craving the light... until they reach the top and the fungus kills them, so it can send out its spores, successfully distributing them far and wide to the jungle floor far below. Yes... that's it - as good an answer as any - we must be adrenaline addicted zombies following orders from our parasites!

That'll give you a reason to stay up!
