Fuel for Workouts? continued...
"If you take an energy drink before exercise, it could increase your blood pressure, overstimulate your heart or nervous system, resulting in a number of potential side effects on your body," she says. "You might think there would be no risk to drinking an energy drink, but some of these products have powerful, drug-like effects and should not be underestimated."
If you want to try an energy drink, she recommends trying a small amount the first time with a meal to see how your body reacts to it. She advises avoiding physical exertion during this trial period.
Need a Boost?
When you need a boost -- whether to study for a test, prepare for a workout, or just get past an afternoon slump -- there are healthier ways than energy drinks, the experts say. Among the energy-boosters they recommend are a healthy diet, physical activity, and a good night's sleep.
And when you need a quick fix? "Energy drinks sound like they would be better than a latte, but a coffee drink made with skim or soy milk is a much better choice because we know more about the effects of caffeine," says Sass.
They recommend no more than 2-3 servings a day of caffeinated beverages, preferably served along with food. If you find caffeine overly stimulating, try decaf or half-caffeinated beverages.
Other energizing beverages include sports drinks, fruit juices, water, low-fat milk, and good, old- fashioned water. "Drink more water," suggests Farrell. "Being dehydrated can lead to fatigue."
Also make sure you're getting enough carbohydrates. Fresh and dried fruit, vegetables, cereal, low-fat yogurt, and whole-grain breads are just a few of the many nourishing foods that can give you energy.
Eat meals every few hours, don't skip meals, and take a good look at your eating and sleeping habits, suggests Farrell.
If you're feeling run down, Sass suggests taking a look at the reasons why you are so tired instead of trying to fix it with energy drinks.
