The caffeine in coffee acts as a mild stimulant to the central nervous system.

Coffee is enjoyed by millions of people around the world and is one of the most extensively researched components in the diet. New studies are regularly being added to the already large body of scientific research. Taken overall, the research indicates that moderate coffee consumption (typically 3-5 cups per day) fits well with a healthy balanced diet and active lifestyle.

Decaffeination removes nearly all the caffeine from the beans. It is carried out while the beans are still ‘green’, before they are roasted. Under European law decaffeinated coffee must contain 0.1%, or less, caffeine in roasted coffee beans, and up to 0.3%, or less, in soluble/instant coffee.

There is convincing evidence that moderate caffeine intake helps to improve alertness and attention (concentration). The European Food Safety Authority (EFSA) recently concluded that a cause and effect relationship has been established between a 75mg serving of caffeine – the amount found in approximately one regular cup of coffee – and both increased attention and alertness.
Brain mapping technology indicates that caffeine is not linked to the brain circuit of dependence.
Abrupt cessation of caffeine consumption may induce withdrawal symptoms in a subset of the population however, these are not generally very severe, are of short duration, and can be avoided by progressive reduction of caffeine intake.
There are some indications that caffeine abstinence could improve sleep, both time taken to fall asleep and sleep quality, though human sensitivity to the effects of caffeine on sleep is variable and genetic differences are known to play a role.
There is some evidence to suggest potential benefits of coffee and caffeine in situations which require increased alertness, e.g. night shifts and jet lag.
