Effects of Caffeine
In November 2010, the University of Texas Medical School at Houston reported that energy drinks contain more caffeine than a strong cup of coffee, and that the caffeine combined with other ingredients (sometimes not reported correctly on labels) such as guarana, taurine, other herbs, vitamins and minerals may interact. Energy drinks consumed with alcohol may affect heart rates, blood pressure and even mental states. The caffeine content of energy drinks range from 80–300 mg per 16-oz serving whereas a 16-oz cup of coffee can contain 70–200 mg.
Health experts say caffeine prevents sleepiness and delays the feeling of drunkenness normally experienced when drinking alcohol, causing some people to continue drinking after they normally would have stopped. Both caffeine and alcohol are diuretics, so mixing energy drinks with alcohol can cause severe dehydration, possibly leading to vomiting, nausea, and other health problems in the long term.
