Can Energy Drinks boost a person’s energy?

December 13, 2015 | By | Reply

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.

Energy drinks that contain sugar may contribute to weight gain — and too much caffeine, sometime 5 times more than a cup of coffee, can lead to:

  • Nervousness
  • Irritability
  • Insomnia
  • Rapid heartbeat
  • Increased blood pressure

Here’s what you can expect after drinking an energy drink:

  • After 10 minutes: The caffeine first enters your bloodstream. Your heart rate and blood pressure start to rise.
  • In 15 to 45 minutes: The caffeine level peaks in your bloodstream. The stimulant starts to affect you, improving not only concentration, but also how alert you are.
  • In 30 to 50 minutes: All of the caffeine is fully absorbed by your body. Your liver also responds by absorbing more sugar.
  • In one hour: Your body starts to experience a sugar crash and the effects of the caffeine begin to die down. You’ll start to feel tired and low-energy.
  • In five to six hours: This is the half-life of the caffeine. In other words, it takes this much time for your body to reduce the content of caffeine in your bloodstream by 50 percent. Women on birth control pills require double the length for their body to reduce it.
  • In 12 hours: The time that it takes most people to fully remove caffeine from their bloodstream, depending on their age and activity level.
  • In 12 to 24 hours: Withdrawal symptoms kick in, including headaches, irritability, and constipation.
  • Seven to 12 days: Studies have shown this to be the time frame for your body to become tolerant to regular caffeine intake, making you feel the effects less.

Can Energy Drinks really boost a person's energy?

“That doesn’t even include concerns about all the sugar and calories in energy drinks, . A 12-ounce can of Red Bull contains 110 calories and 27 grams of sugar. Energy drinks are fine in moderation and as part of a balanced diet,” the studies conclude.

Occasional energy drinks are fine, but try to limit yourself to about 16 ounces (500 milliliters) a day.
