The Kick Behind Caffeine

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

Ouija Board and the Ideomotor Response (Source: Wikipedia) Following its commercial introduction by businessman Elijah Bond on July 1, 1890, the Ouija board was regarded as a parlor game unrelated to the occult until American Spiritualist Pearl Curran popularized its use as a divining tool during World War I. Spiritualists believed that the dead were able to contact the living and reportedly used a talking board very similar to a modern Ouija board at their camps in Ohio in 1886 to ostensibly enable faster communication with spirits. Paranormal and supernatural beliefs associated with Ouija have been harshly criticized by the scientific community, since they are characterized as pseudoscience. The action of the board can be parsimoniously explained by unconscious movements of those controlling the pointer, a psychophysiological phenomenon known as the ideomotor effect Ideomotor phenomenon is a psychological phenomenon wherein a subject makes motions unconsciously. The phrase is most commonly used in reference to the process whereby a thought or mental image brings about a seemingly "reflexive" or automatic muscular reaction, often of minuscule degree, and potentially outside of the awareness of the subject. As in reflexive responses to pain, the body sometimes reacts reflexively with an ideomotor effect to ideas alone without the person consciously deciding to take action. The effects of automatic writing, dowsing, facilitated communication, and Ouija boards have been attributed to the phenomenon. Mystics have often attributed these effects to paranormal or supernatural force. Many subjects are unconvinced that their actions are originating solely from within themselves. Scientific tests by the English scientist Michael Faraday, Manchester surgeon James Braid, the French chemist Michel Eugène Chevreul, and the American psychologists William James and Ray Hyman have demonstrated that many phenomena attributed to spiritual or paranormal forces, or to mysterious "energies," are actually due to ideomotor action. Furthermore, these tests demonstrate that "honest, intelligent people can unconsciously engage in muscular activity that is consistent with their expectations".[9] They also show that suggestions that can guide behavior can be given by subtle clues (Hyman 1977).
