Coffee is one of the most popular bevarges in the world .There are good reasons to drink coffee and there are a few reasons not to. You may be surpised to know that it is not necessary to drink it you can also get benefit by just looking at it.   The study, published in the journal Consciousness and Cognition, looks at an effect called priming, through which exposure to even subtle cues can influence our thoughts and behaviour.

Sam Maglio, Associate Professor at the University of Toronto in Canada, said, ‘People often encounter coffee-related cues, or think about coffee without actually ingesting it," Maglio said. The team used a mix of participants from Western and Eastern cultures "to see if there was an association between coffee and arousal such that if we simply exposed people to coffee-related cues, their physiological arousal would increase, as it would if they had actually drank coffee.”

They found that participants exposed to coffee-related cues perceived time as shorter and thought in more concrete, precise terms.

Maglio said, "People who experience physiological arousal -- again, in this case as the result of priming and not drinking coffee itself -- see the world in more specific, detailed terms,"

 "However, the study noted that the association between coffee and arousal is not as strong in less coffee-dominated cultures.
