Have you ever felt so tired after staying up for a night that even coffee doesn’t give you the energy that you need? You may have an energy drink, but the benefits of drinking one are heavily outweighed by the risks.
In the past years, more and more studies have found the deadly effects of energy drinks on our bodies. The sugar,
caffeine and energy supplements ( 添 加 物 ) in energy drinks make up a deadly mixture of ingredients that can affect your heart function and send you to the hospital!
A study by the University of Bonn, Germany found that frequent consumption of energy drinks can greatly change the way our heart functions. The study went on to say that consuming energy drinks often causes significantly increased heart
contractions (收缩) in adults, which has the potential of putting you at risk for irregular heartbeats.
It is possible that many people are unaware of the alarming side effects of energy drinks because of the way they are labeled. Most energy drinks contain between 80 milligrams to over 350 milligrams of caffeine, sugar and energy supplements. When an energy drink is marketed as a diet supplement it may be distributed without a “nutrition facts” label, which would show the harmful supplements that are in the drink. However, even if energy drinks are Food and Drug Administration (FDA) approved, they don’t have to show the number of supplements.
Energy drinks may be widely available but they aren’t the healthiest or safest choice for your body. To stay naturally energized, get organized and stay on top of your work so that you aren’t having to stay up all night to complete assigned tasks. If you’d like a natural energy boost you could make time for a short workout, which will give you all of the energy you need!
