Effects Of Energy Drinks On Health

Energy Slumps

The body gets energy from sugar, caffeine provides alertness (or at least a delayed fatigue response), and B12 also increases energy levels. However, once you consume energy drinks, you're likely to experience energy slumps for several reasons. First, when your body burns through the sugar surplus from the drink, the insulin and sudden lack of sugar cause a sugar crash. Second, caffeine stimulates a mild to moderate production of adrenaline. The adrenaline response creates an even more rapid energy burn, and after it's depleted, you will crash because adrenaline burns through the body's supply of energy more completely than would happen otherwise. The chronic lack of sleep associated with consuming too many energy drinks also adds up and lowers overall energy levels.

Effects On The Heart

Energy drinks have been shown to have harmful effects on the heart. Although caffeine in excessive doses can cause problems, most energy drinks contain other ingredients that are not FDA-approved and have been shown to induce heart arrhythmia. Taurine and proprietary blends frequently included in these drinks are not necessarily safe for human consumption because they cause such negative effects. Ingredients such as taurine can stimulate the production of adrenaline and in turn an episode of the body going into a fight-or-flight response. This creates an increased strain on the heart because of the increased demand for oxygen in the bloodstream.
