Caffeine Addicts Get No Additional Perk, Only a Return To Baseline

Dthief writes "Bristol University researchers found that coffee drinkers develop a tolerance to both the anxiety-producing and the stimulating effects of caffeine, meaning that it only brings them back to baseline levels of alertness, not above them. 'Although frequent consumers feel alerted by caffeine, especially by their morning tea, coffee, or other caffeine-containing drink, evidence suggests that this is actually merely the reversal of the fatiguing effects of acute caffeine withdrawal,' wrote the scientists, led by Peter Rogers of Bristol's department of experimental psychology."

      I don't actually have anything against coffee, but I don't drink it because I can wake up on my own, and I don't find its taste compelling enough to drink all the time. I think the comparison between alcohol and caffeine probably has more to do with the reasons people have for drinking it.

      Drinking coffee to wake up every morning will probably lead to dependence. Drinking coffee because it tastes good, at somewhat irregular times, probably won't. Similarly, drinking beer just because it's delicious(*) and the light buzz is pleasant probably won't lead to dependence, but drinking to make yourself happier or to "escape" in any way probably will. It's much easier to become dependent on something that you, you know, depend on.

    And if you stop drinking coffee your body will adapt to waking up on its own with no need for it. I used to drink tons of soda (even more caffeine than coffee) and always had to have a can in the morning to wake up, I stopped drinking it (well aside from about 2 cans worth a week) and suddenly it was significantly easier to get up in the morning, to the point where, going to sleep at the same time, I was waking up an hour earlier and feeling much better.

    Caffeine is not a good way to start your day off, no matter what folgers may say. It's a useful drug for maintaining alertness every once in a while but used daily it reduces your overall alertness, which is bad.

    This study asked people to 'rate their levels of alertness' after being given either caffeine or a placebo. The people who normally consumed caffeine rated their alertness levels the same after receiving caffeine as the non-caffeine users rated their alertness levels after receiving a placebo.

    Now this could mean a couple of things. One meaning could be what the study authors said; that caffeine addicts need their caffeine to be at the same level of alertness that non-caffeine users need. OR it could mean that the non-caffeine users aren't used to the higher levels of alertness that caffeine gives you, and therefore don't use the same scale to rate their alertness that caffeine users do. A caffeine user may think that the 'normal' (non-caffeinated) level of alertness is actually low (because they are used to being more alert from caffeine) even though they have the same 'actual' level of alertness. In other words, non-caffeinated people might not realize how un-alert they are.

    A much better test would be to actually TEST their alertness, instead of relying on a subjective self-assessment. Make them do tasks that require alertness, and measure the differences. You might get different results.

All were asked to rate their personal levels of anxiety, alertness and headache before and after being given either the caffeine or the placebo. They were also asked to carry out a series of computer tasks to test for their levels of memory, attentiveness and vigilance.

  18. Same with sugar rush in kids by SmallFurryCreature · · Score: 5, Interesting

    US TV shows can't resist putting in the effects of sugar on kids. And nobody ever noticed that anywhere else in the world. Maybe because IT IS NOT TRUE. Yes you can energy from sugar but the human body has plenty of sugar all the time on a normal diet. It isn't going to hyper because you add more fuel to it, you just get fatter because the body can now store fat for later instead of burning it as it should.

    Clinical trials have shown that kids have no sugar rush UNLESS the parent who thinks kids get a sugar rush are present and then the kids do indeed become hyper active. So over-sensitive parents cause hyper-active children. Not sugar. (That parents infleuence the actions of they child is well known, simple experiment: put a baby who can crawl on a surface and let it crawl over a gap covered by a glass plate. The baby will have no reaction of its own to the height below it. If the mother shows delight then the baby will show it, and cross happily. If the mother shows horror, the baby will react in fear trying to determine what danger it is in. This is how we learn, how all animals with parents learn. But we can learn wrong if the input is wrong. Over-protective parents cause over-sensitive children. Yes, sometimes kids just need to walk it off and funnily enough, they do. Watch a child playing on its own. It falls, nobody panics, it continues.)

    Same with coffee. Some writer probably thought it was funny and now everyone believes sitcom rules apply to the real world. Yes, cafine is different from sugar in that it is a drug and does have an effect but you need to be the kind who drinks energy drinks as if they were water, with no water. Not just a cup of coffee. Even half a dozen.

    It think part of it is that people act the way they think they are supposed to act. And yes, that would be very intresting to study more because it might have a serious effect on health care. For instance the use of medication when it ain't needed. If you think you need a pill for everything, you will need a pill for everything and indeed get a pill for everything. The US is the most medicated nation on the planet and yet they aren't any healthier. What is all the non-needed drugs doing? Not just to health but to the health care costs? If media is causing people to think they have to behave in a bad way, perhaps it can be reversed as well. Less pill swallowing for every ailment in popular media content could perhaps translate to lower medicine costs?
