How Can Business Teams Boost their Performance with Coffee? by Jennifer Dawson

The number of Americans drinking coffee is at its highest level in six years. A recent survey carried out by the National Coffee Association indicated that 64% of Americans aged 18 or over said they had had a cup of coffee the day before they were surveyed, while only 62% reported the same last year. Gourmet coffee is particularly big among millennials, yet most people still make their own brew at home. If you are a coffee drinker yourself and you like to have at least one top-up at work, here’s the good news: coffee can boost your team’s concentration and memory in many more ways than you imagined, plus deliver health benefits such as protection against Type 2 diabetes, heart disease, and many types of cancer.

Coffee Boosts Work Alertness

A 2018 study by scientists at Ohio University found that work groups received more positive reviews for their performance after enjoying a cup of caffeinated coffee. Not only were people more communicative after a cup of ‘black gold’, but they were also more on-topic. The lead researcher of the study, A Singh, noted: “We found that increased alertness was what led to the positive results for team performance. Not surprisingly, people who drank caffeinated coffee tended to be more alert.” Coffee can also improve attitude in teams. Singh notes that workers who are more alert see themselves and others as being more contributive to the tasks at hand, which results in increased positivity.

Getting the Right Algorithm

A fascinating 2018 study published by the American Academy of Sleep Medicine found that a specific algorithm can be the key to optimizing alertness with caffeine. By determining the exact time and quantity of caffeine that should be drunk, alertness can be boosted by 64%. Did the scientists share their complex algorithm? Sadly, the answer is no, but fear not; you can at least get the flavour right. There is an online brew calculator that will guarantee the ideal ratio of ground coffee to water for your taste. All it takes is a little experimentation; once you hit on the winning combination, you can always count on the perfect cup of coffee to start the day.


The Effect of Caffeine on Memory

Studies have also shown that caffeine can enhance the memory. One double blind trial, carried out at John Hopkins University, found that participants performed better on memory tests after consuming a 200 milligram caffeine tablet five minutes after studying a series of images. Caffeine consumption is also linked to longevity, and many have protective effects against diseases involving cognitive decline (including Alzheimer’s disease).

There have been many studies carried out on caffeine and coffee and thankfully for coffee lovers, most indicate a plethora of possible benefits: everything from improvements in chronic pain to advantages in sports performance, cognitive tasks, and more. We also know that coffee can make us more alert, thus boosting work performance and enhancing one’s interest in other members of one’s team.
