“Improve your concentration! Feel more energetic Perfonn better!" promise the advertisements for many of the popular enegy drinks. But do these beverages really live up to these promises? Well, they seem to, at least temporariIy. These drinks are basically a mixture of caffeine an sugar. Caffeine is a míld stimulant that can create alertness and energy levels. Altbough amounts differ among manufacturersc energy’ drinks generally contain about fue same amount of caffeine as a cup of coffee. As a comparison cola has about half the amount.Most energy drinks also have quite a large clase of sugar, which is another source of quick energy. In addition some of the drinks also contain some vitamins, and extracts from plants that are believed to have some health benefits.
So with little new to offer, how have fuese beverages become the favourite drinks for millions of young people, whether before exams or while out partying? The answer is probably because of the young vigous image promoted in advertising campaigns directed mainly at people under thirty. This image is further emphasised through youth-oriented sports and music events sponsored by some of the major manufacturers, by which they link their names to achievement and enjoyment. And finally, there’s fue trendy packaging, which is often colourful and in some cases resembles beer cans.
There are a few things that energy-drink fans should keep in mmd. First, do not mix the drinks with alcohol. According to some recent research, the combination could cause heart problems. And, if you drink them before or during physÍcal activity, such as running or dancing, be sure also to drink a lot of water, as high amounts of caffeine cause the body to lose more fluid than normal. Finally, remember that energy drinks provide only a temporaly increase in energy. If you’re aiming for long-lasting high energy levels and increased concentration, a healthy diet, plenty of exercise and enough sleep are more etfective than energy in a can.
