When we consume caffeine, our ability to recognize words with positive connotations increases, according to a neuroscientific study published in the journal PLOS ONE . Specifically, the researchers' work reveals that consuming 200 milligrams of caffeine – the equivalent of 2 or 3 cups of coffee – increases receptivity to positive emotionally charged language (such as "happy", "party" within half an hour). , "hero" or "weekend"), but has no effect on emotionally negative or neutral terms. The authors, from Ruhr University (Germany), suggest that it is due to the fact that caffeine enhances the transmission of dopaminergic stimuli in the brain regions responsible for processing language, located in the left hemisphere.
Caffeine had previously been shown to improve results in simple cognitive tasks, but this is the first time that its consumption has been linked to changes in the perception of emotions.
