Consequences of Caffeine

 Every morning people wake up to a nice and hot cup of coffee, including me, and every morning I am reminded of 17 years ago, when I would sit on my great-grandfather’s lap sipping his coffee and dunking delicious vanilla wafers in his coffee. With school in full swing, it seems that after each passing day it gets a little harder to wake up, so we all drink coffee. But why? Why has coffee become the go-to picker-upper in the mornings? Obviously this is a rhetorical question because everybody knows that the one ingredient, the one “miracle-worker” for the morning blues, is caffeine.

An article by Discovery Fit and Health adequately describes the mechanical process of how caffeine keeps you awake. In short, caffeine tricks the brain into accepting it by looking and acting like another molecule, adenosine. A natural build up in adenosine leads to drowsiness, but caffeine fools the brain into accepting it instead of adenosine, slowing down the brains reaction to sleepiness. Sounds complicated! What I found interesting about this was the process of “tricking” the brain. To me, fooling your body into thinking something else doesn’t seem natural, and as my gut told me, it truly is unnatural.

Initially, coffee was identified with adults because young children seem to already have enough energy to go around. But with the advent of more “exotic” or “special” types of coffee produced by corporate chains, caffeine has been spreading to younger and younger people. In a recent study by the Swiss National Science Foundation some possible side effects of caffeine for young adults have been identified. The study was based on the fact that, in both humans and rats, the greatest maturation of the brain occurs during childhood and is highest during puberty. Thus the group studied the effects of caffeine on rats during their growth period. In conclusion, they found that the rats that were given caffeine begin a deep sleep period, which is characteristic of puberty, much later than the control group (given water). Overall, the addition of caffeine to the diet of the rats during their pubescent period greatly delayed the development of their brains. The caffeine that is supposed to wake you up actually slowed the growth period down, not good!

 Now rats are far from human, so don’t freak out! I mean we have all heard the comparison, “are you a man or a mouse?” Although on the other hand, rats do have several biological similarities to humans, so there is slight cause to be worried. They may be small and they may be less developed, but their biological processes and organs all have several similarities. Take what you will out of the information; caffeine has NOT been proven to be absolutely harmful to humans, yet. And so I and every other dreary individual will continue the morning routine, summing it up with a steaming cup of coffee, for now.

  1. Charlie,

    Thanks for the blog post. It seems caffeine has been popular as a performance enhancing drug within hockey (and many other sports!) for quite some time.

    I'm noticing a pattern for "What's Ur Rxn?" blog posts: the introductions are all catchy. I like it!

    I was unaware that caffeine is a substitute for adenosine in the brain. Thanks for sharing that. I learned something new here. Did you compare the chemical structures of the two to see how similar they are? If caffeine is binding to a receptor, it seems like it must be close enough in structure to mimic the adenosine.

    One other thought: On my screen, the links aren't in a different color, so I didn't know right away that you actually included them. It was only when I went to move my mouse and it accidentally caught a link that changed color that I found them. I'm not sure if it's a setting, but it would be helpful for your readers to see the links distinctly.

    Thanks again for the post.

    If you have time, I'd request that you visit my students' blogs also. We're early in our process of blogging, but they are linked from the "Student Blogs" page of http://aisbchemblog.wordpress.com. I'm sure my students would appreciate some comments.

    Thanks again for your blog post.

    Mr. T
