Consumption of energy drinks which contain huge amounts of sugar and caffeine by has been linked to headaches, palpitations as well as triggering bad behaviours in the classroom and school yard, under-16s.

It comes after researchers at Fuse, the Centre for Translational Research in Public Health, based at Teesside University, United Kingdom, found that energy drinks were being sold to children for less money than water or fizzy drinks.

A single 500ml can of popular brands on the market can contain around 160mg of caffeine, while the European Food Safety Authority recommends an intake of no more than 105mg caffeine per day for an average 11-year-old.
