In a period of four years, emergency room visits tied to energy drinks doubled, with teens and young adults accounting for more than half of the visits, CBS reported this month. According to the article, one drink might contain the caffeine equivalent of 5 cups of coffee, so it’s no wonder that emergency room physicians are seeing “a clear uptick in the number of patients suffering from irregular heartbeats, anxiety and heart attacks who said they had recently downed an energy drink.” Two senators are calling for the FDA to study the issue, after reports of energy drinks leading to “insomnia, nervousness, headache, fast heartbeat and seizures….” The top three energy drink brands (in case you aren’t aware of what your child could be consuming) are Red Bull, Monster, and Rock Star.
