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.

Charlie,
ReplyDeleteThanks 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
Thanks for the info on caffeine. I shared the following videos with my students and wanted to pass it along.
