Coffee is the most consumed drink in the world, after water, and this is even true in Britain, a nation renowned for its tea drinkers. With this in mind, it is no surprise that most of us use it to get through the work day; one of the most well known effects of coffee is its ability to increase your alertness, concentration and energy levels. But what is the truth behind this? Does caffeine have a positive effect on your concentration levels at work?

Productivity At Work

Research was conducted by Stong Vend, a London based coffee vending specialist company, into the effects caffeine on productivity at work. The research turned up some surprising results. They conducted the research on a digital agency called Cyber-Duck, whose employees were big coffee drinkers. The participants were not allowed to drink coffee for one week, and completed daily surveys answering questions about their mood, concentration levels, motivation and overall performance. After the week of no coffee drinking, a week of normal coffee drinking ensued and the participants again answered the same questions. The research found that the work force was a huge 19% more productive when drinking coffee, meaning that regular coffee consumption in the office increases the mood, motivation and overall productivity of the staff.

Reduction In Workplace Accidents

This may surprise you(!), but a 2005 study found that caffeine actually reduces the amount of workplace accidents. The study of 1555 white collar workers involved monitoring the levels of caffeine that individuals consumed, and dividing them into groups based on whether their intake was high, medium or low. The study found that there were less cognitive failures for those who drank medium to high amounts of caffeine.

Caffeine May Improve Your Work Relationships

Now here we are not just talking about the time you stand around chatting when you’re making a cup of coffee, but about a physiological effect of caffeine. A study was conducted where participants were asked to play the Mixed Motive Game (a game that emulates social interaction by forcing players to reach their aims by either competing or cooperating against  other players. A common example is the prisoner’s dilemma). The participants didn’t know whether they had consumed caffeine or not. The study found that the caffeine consumers showed more signs of social support and empathy, than the non-caffeine consumers.
