> Is there actually any evidence that caffeine is bad for kids It's complicated as there can be beneficial effects as well. The issue is likely with the dosage as typical tea drinking hasn't seemed to cause any issues and us brits have been drinking tea for a long time. I've heard anecdotes of extreme coffee drinking (multiple espressos over a short time) causing heart palpitations, but that's not common as excessive coffee tends to make people jittery (c.f. Futurama episode where Fry drinks 100 coffees). Energy drinks have high levels of caffeine and high levels of sugar and tend to be chugged, so they're likely to excessive doses. Found this review is likely relevant and in my view, the sleep disruption is a red flag for a healthy lifestyle: https://pmc.ncbi.nlm.nih.gov/articles/PMC7177467/ https://pmc.ncbi.nlm.nih.gov/articles/PMC7177467/
