We might remember on National Coffee Day that the American Academy of Pediatrics recommends that children and teens avoid coffee and energy drinks, since caffeine can cause them to have sleep problems, high blood pressure, and a rapid heart rate.

Teenagers and young adults spend billions on heavily caffeinated drinks with names like Monster, Red Bull, Amp and Full Throttle. However, the caffeine in these products may be having more of an impact than just trouble getting sleep.
