Energy drinks: Do they really give you energy?

Energy drinks may give you a temporary energy boost. The "boost" typically comes from the large amount of sugar and caffeine these drinks contain.

Although the various sugars used to sweeten energy drinks can briefly increase energy, consuming large quantities of sugar is likely to cause weight gain. Caffeine is a stimulant, which also can temporarily perk you up. But too much caffeine can cause adverse side effects, such as nervousness, irritability, increased heart rate and blood pressure, and insomnia.

Energy drinks are not necessarily bad for your health. But you shouldn't see them as some "natural" energy boost — the boost they give is from caffeine. Some of the claims made by manufacturers of energy drinks — such as "improves performance and increases concentration" — can be misleading.

Consider a better way to boost your energy: Get adequate sleep, exercise regularly and eat a healthy diet. These strategies not only will increase your energy in the short run, but also will help you maintain your overall physical and mental fitness in the long run.
