Energy drinks: Do they really boost energy?
Can energy drinks really boost a person's energy?

Answer
from Katherine Zeratsky, R.D., L.D.

Most energy drinks contain large amounts of caffeine, which can provide a temporary energy boost. Some energy drinks contain sugar and other substances. The boost is short-lived, however, and may be accompanied by other problems.

For example, energy drinks that contain sugar may contribute to weight gain — and too much caffeine can lead to:

* Nervousness
* Irritability
* Insomnia
* Rapid heart beat
* Increased blood pressure

Mixing energy drinks with alcohol may be even more problematic. Energy drinks can blunt the feeling of intoxication, which may lead to heavier drinking and alcohol-related injuries.

For most people, occasional energy drinks are fine. If you're consistently fatigued or rundown, however, consider a better — and healthier — way to boost your energy. Get adequate sleep, include physical activity in your daily routine and eat a healthy diet. If these strategies don't seem to help, consult your doctor. Sometimes fatigue is a sign of an underlying medical condition, such as hypothyroidism or anemia.
