Random Research: Caffeine

Today was my first second (I can even procrastinate finishing blogposts!) day of study for exams. It was the first second of many, many days, leading up to the 16th of November, the day of my last exam. Between now and then, I will hardly have a day's rest, not only because of exams and cramming (as outlined a few posts previously), but also because November is already knocking on my door, and my NaNoWriMo novel is SO not ready to be written yet! I mean, I don't even have character names yet! I now have names for my most important characters, but the whole project is still more of a plothole than anything.

You guys know what this means, right? It means that, in order to keep my head above the water, I'm going to need LOTS AND LOTS OF CAFFEINE. Everyone who's ever done NaNoWriMo (or gone to university in general, I'm guessing) is very, very familiar with this solution. That, and sugar, but I'd like to focus on caffeine for now. And because for some reason, I seem to get the best ideas when I'm supposed to be doing something else, like studying for my philosophy exam -- actually, specifically when studying for my philosophy exam, because I'd rather be doing about a gazillion things than studying for it -- I decided that it was finally time to satisfy my curiosity about caffeine. And then, figuring that you guys are probably either also nerds or geeks and/or doing NaNo and/or going to university, I thought I'd share.

 Caffeine, or, between friends, 3,7-dihydro-1,3,4-trimethyl-1Hpurine-2,6-dione, is a psychoactive drug, meaning that it mainly affects your central nervous system and through that, your brain, altering your behaviour and state of mind. Apart from that ridiculously long IUPAC name, doesn't sound like a whole lot of new information, does it? The interesting bit of information follows: apparently, caffeine is able to do this to our brains, because it is very similar to a chemical that is already present in our bodies: adenosine.

Adenosine accumulates in your brain after long periods of concentration or alertness, and that is interpreted in our brain as a signal to rest or sleep in order to give your poor, hard-worked neurons some time to relax. But no, that really important thing is on tomorrow, you can't afford to lose any time on pesky rest right now! So you go and make yourself a biiiiig cup of coffee, the caffeine molecules swimming around in your cup, and, before long, in your brain, blocking the receptors that usually detect adenosine, keeping you alert and focused for juuust a little bit longer.

Sounds like a pretty sweet deal, doesn't it? Fortunately, too, caffeine doesn't appear to have that many adverse side-effects: though it is claimed to be a diuretic, thereby leading to dehydration, the generally accepted view is that this is not true, and that any such effect caused by caffeine is similar to that of water. Previously, it had also been thought to increase blood pressure, but recent studies have shown no such connection. There's a whole list of risks and benefits of caffeine listed on wikipedia, if you're interested -- I only glanced at the list, but I didn't see anything there that was blatantly contradicted by the rest of my research; still, take it with a grain of salt. I guess the fact that it appears relatively harmless makes sense: I wouldn't think that anything ultimately harmful to humans could be used as widely as caffeine is, what with the knowledge we have of biochemistry today.

So, the only thing you really have to worry about in your reckless coffee consumption is addiction. Like any other drug, caffeine is addictive, and, when used extensively will eventually cause withdrawal symptoms like headaches, muscle pain, irritation, and so on and so forth. One site I visited also claimed that caffeine consumption can turn into a vicious cycle: though its effects diminish over time, as with alcohol, there will be a measure left in your body, and that might disrupt your deep sleep pattern, leading to restless sleep, which, then, leads to more excessive caffeine intake.

That's all I've got for now, folks! Hope none of you get caught in the vicious caffeine cycle in the vicious month that is called November (I know I'm about six days off the start of November, but it's appropriate, ok?); and if you are, well, at least it's delicious, delicious coffee, right?
