The Kick Behind Caffeine

The Kick Behind Caffeine - Reviewed by Kidzworld on Dec 27, 2006

Even if you're just drinking coffee or pop because you like the taste, the caffeine will still kick in and perk you up. Read on to find out how caffeine can make people bounce off walls.

Whether you drink coffee or not most of us put caffeine in our body. Some of us do it cuz we want the energy rush. Whether we eat or drink caffeine to stay awake or just because we like the flavor, the effect is still the same. What is it about caffeine that gives us that extra boost of energy?

When we sleep a chemical in our brain called adenosine clings to receptors and slows down all activity happening in there. Like the drugs cocaine and speed, caffeine is able to fool the adenosine receptors by looking like the cells it is blocking, the adenosine. The caffeine completely takes over where receptors would normally cling. This makes it hard for the receptors to do their job.

That's not all that happens. Caffeine causes blood vessels in the brain to tighten which means not a lot of oxygen can get into the bloodstream. This is why you can't get a good nights sleep if you drink coffee at night - caffeine blocks what you need to have a deep sleep.

Still with me? Keep reading to find out where that energy comes from. All this activity in the brain alerts the pituitary gland (a small oval in the brain that controls growth, metabolism and maturity.) This gland thinks there's an emergency and releases adrenaline. What you get are cold hands, tense muscles, an excited feeling and an increase in heart rate.

If that doesn't convince you to go pour a cup of coffee or crack open a Jolt cola, you might want to know this. Caffeine also increases dopamine levels (transmitters for your nervous system) just like heroine and cocaine. This excites the part of your brain that controls pleasure and helps the drug become addictive.

Did you know that the pop with the most caffeine in it is Afri-Cola followed by Jolt? Mountain Dew has more caffeine in it than Coca-Cola, except in Canada where the Dew doesn't do caffeine. Coca-Cola, which has more caffeine than Pepsi, has the same amount as Diet Coca-Cola.

1 I've never learned this much about Caffeine before! Wow! Caffeine sure is the thing you want when you want to watch a scary movie at night! I'm gonna drink lots of coffee, being able to stay up late on New Year's Eve!

How long can you go without a Coke? Do you start going into withdrawl symptoms after 24 hours without one? If your fingers stop shaking enough, drop us a comment below

What Gives You a Boost of Energy?

  • Caffeine does the trick for me.
  • 23 sugar cubes is usually enough.
  • A chocolate bar.
  • A raw egg and milk shake.

It's very interesting what you can find outside or inside, for example, a coffee shop or restaurant.I also am really into drawing animals, especially my three cats. No problem. (: If you have any questions, feel free to ask, I'll be glad to help. That's very interesting. I don't know many people who use mostly watercolours. Finding inspiration from the simplest things is a part of what makes drawing, and any type of art, fun.  I can't draw animals for the life of me, haha. I'm working on it though. Do you find the textures easy? Fur seems a bit complicated.
