Energy drinks come in highly colored cans that are enticing to teens who use them to wake up in the morning and endure all night study sessions. These drinks are used to jump start people in the morning and revive them from the afternoon slump. The carbonated drinks contain 40 - 80 milligrams of caffeine. One of the most popular energy drinks on the market is Red Bull.

Caffeine gives a rush that provokes feelings of energy. Some energy drinks tout the ability of their drinks to stimulate the mind. According to some resources, caffeine can overly excite the brain to where people cannot concentrate. Do the makers of energy drinks do not understand that large amounts of caffeine stress the body? It increases the heart rate and what might happen to someone with an undiagnosed heart condition is revved up with several drinks? The problem with athletes drinking several cans before a game is that they tend to chug them down because they are cold and taste good. They hit the system all at once along with the adrenaline of competition.

Some young adults mix energy drinks with alcohol to get a quick buzz. For some time, people have thought that pouring caffeinated coffee into a drunk is sobering. Not true. It stands to reason if you do this, you end up with a wide awake drunk. In addition to the sugar and caffeine in energy drinks they contain large amounts of acids. These acids damage the tooth enamel. The young adults who use energy drinks heavily do not realize that they are actually impaired in their thinking and concentration. People who are sensitive to caffeine should probably avoid energy drinks.
