I don’t buy it. “Caffeine addicts get no perk”
Posted On June 7, 2010
British scientists report that caffeine consumers actually “get no perk” from their morning joe. I don’t buy it.
It is true, as they say, that we develop a tolerance to caffeine over time. But they’re saying that “Although frequent consumers feel alerted by caffeine, evidence suggests that this is actually merely the reversal of the fatiguing effects of acute caffeine withdrawal”
In other words, when you wake up groggy, have your morning cup, and feel more alert, you’re not actually feeling more alert. Huh?
Here’s how they came to this counterintuitive bit of silliness. They got caffeine users to go off it for 16 hrs. They then gave them a caffeine pill, or a placebo.
THEN … they had the individuals themselves rate how alert they felt like they were, and compared that to the “alertness” of non-consumers. These two, completely different, self-reported guestimates turned out to be similar. And THAT’s how they came up with the conclusion that you read in the title: Caffeine addiction is such a downer that regular coffee drinkers may get no real pick-me-up from their morning cup.
You can’t even compare two different sets of subjective data like this. So don’t doubt your senses, you caffeine fiends. The increase in alertness you feel, is not a mirage.
