I’ve written before about the benefits of moderate caffeine and coffee consumption. A new review of studies looking at the effect of caffeine intake on shift workers (14% of Americans) show that it will cut down on work related errors and increase productivity.
Depending on the study design, the workers received caffeine through coffee, energy drinks, food, or pills. In most studies, the workers completed neuropsychological tests to gauge their memory, attention, reasoning, and perception skills. Several studies compared the results of neuropsychological testing in participants given caffeine versus a placebo.
The study authors say that, compared to doing nothing at all, the caffeine helped shift workers improve their cognitive performance and reduced job-related errors. None of the studies reviewed assessed the effects of caffeine on work-related injuries.
