Another good news for coffee lovers like me: Caffeine found to boost positivity
If you are a coffee lover like me, you might just have to add another reason to your long list of reasons for drinking that taste of heaven in a cup.
A new research done by researchers from Ruhr University in Germany found out that caffeine may boost positivity and save one from the claws of negativity that abounds in this world.
Sixty-six subjects were part of the study, half of which took a lactose placebo pill and the other half took tablets containing 200 milligrams of caffeine, equivalent to about two or three cups of coffee, thirty minutes before the test. The test comprised of making the subjects identify whether or not a string of letters flashing across a computer screen were real words or not.
The subjects who took in the caffeine pill were able to spot positive words such as "happy" more accurately than the negative or neutral words.
Looks like this ability of caffeine to boost positivity further supports a study published last year in the Archives of Internal Medicine, which included 50,000 women who are drinkers of two or more cups of coffee daily. The study found out that those subjects who drink two or more cups of coffee a day are less likely to get depressed.
According to the health website, LiveScience, prior studies have shown caffeine probably stimulates the central nervous system by increasing activity of the brain chemical dopamine, which is linked with rewards, creativity, impulsivity and addiction. Since caffeine seemed to boost the positivity advantage, these findings suggest the root of the positivity advantage may rest in dopamine.
