    Drinking beer at the wrong time also reduces brainpower. Mmmm, beer...

      And another link at the same site tells us that Beer 'may be good for you'.
      So there you have it.

      Water: bad

  2. Chewing gum effect in reverse by Stormie · · Score: 4

    Dr Rogers thinks that the temperature of the drinks might explain part of the effect. The body has to divert resources to deal with the local cooling effect in the gut.

    When I was at uni, I read in the newspaper one day that a study had shown improved mental performance from people who were chewing gum. The theory was that while you were merrily chewing away, the exercise your jaw was getting required extra blood to be pumped to your head. Some of this ended up in your brain, and it performed better, all pumped up with nice fresh oxygenated blood.

    (OK, that's a horrible pseudoscience explanation, but I'm no biologist, I'm a programmer!)

    Anyway, from that day on I always took a pack of gum into exams, to chew while I worked. Dunno if it helped, but at least psychologically it probably did. :-) Is this a similar effect in reverse? All the blood rushes to your stomach to warm it up after your glass of ice-cold water, and leaves your brain starved? Nice one.

      What helps more is to write cheats on the chewing gum wrapper!

    water has been known to reduce brain power (as have most cold beverages), coffee on the other hand does nothing for your brain power short of being mildly carcinogenic. tea on the other hand (especially green tea) has been proven many times to heighten brain activity, stimulate your mind, as well as mildly reproducing brain cells. pretty amazing being as how tea is basically warm water after having tea leaves added to it.

      its been proven that coffee tends to speed up reaction time a bit for a fairly short period of time, only to lead to a crash (regular old caffeine high). tea on the other hand tends to raise mental stimulation considerably for longer periods of time, without any form of crash, mostly due to the significantly lower amounts of caffiene in tea.

      oh yea, that boston thing, it was about a tax on tea, as a result, most countries still dont tax loose tea sales.
