Energy drinks do not make youngsters smarter, study finds

The researchers gave three groups of fourth year pupils a large glass of energy drink, fruit squash or water. Flavourings were added to disguise the taste of the energy drink and the squash. Afterwards, the subjects were asked to complete a number of written tests that rely on attention and concentration, learning and memory, verbal and numerical reasoning, numerical aptitude and vocabulary.

The results showed that the energy drink had no beneficial effect whatsoever. The authors – three of whom were still at school at the time – warn that the caffeine in the energy drink can cause headaches and insomnia. In addition, intensive consumption of energy drinks can increase the risk of drug use. The journal Pediatrics previously warned about the health risks to young people.

Dr Wilhelm states "Our research shows that, in terms of school performance, there are no grounds to suggest possible benefits to young people that would justify these risks." If you are in need of a study boost, Dr Wilhelm and his fellow researchers advise you to drink coffee or, if you don't like coffee, "to imagine that you've just drunk an energy drink – the effect is probably just as powerful."
