They can lead to difficulty sleeping, headaches, difficulty concentrating, anxiety, and irregular heartbeat. Depending on the amount of stimulant in the beverage, over use can cause toxicity and even death. There is even the risk for physical dependence and addiction to the stimulants in these beverages. Therefore energy drinks are never recommended for children or adolescents and should never be consumed by them.
