It is well recognised that drinking coffee contributes to increased wakefulness and alertness. Most of the study of the benefits of coffee consumption and mental performance is centered on caffeine. There is convincing evidence that moderate caffeine intake helps to improve alertness and concentration. A 75mg serving of caffeine leads to both increased attention and alertness, according to the European Food Safety Authority (EFSA). A typical cup of coffee contains about 100mg caffeine, the coffee we roast and ship to you is about twice these levels. There is evidence indicating potential benefits of coffee & caffeine in situations requiring increased alertness (night shifts at work, studying for extended hours, long-distance driving).Some studies suggest that caffeine abstinence could improve sleep — in context of sleep quality and the time it takes to fall asleep. However, there are large differences between individuals and more research in this area is needed.Brain mapping technology has determined caffeine is not linked to brain circuitry connected to dependence and as a result caffeine does not fulfil the criteria to be described as a drug of dependence. Despite sudden ending of caffeine consumption may induce withdrawal symptoms in a small number of individuals, these are generally not very severe, are of short duration, and can be avoided by gradually reducing caffeine intake.
