While parents recoil at the thought of young teens having coffee with breakfast, permitting energy drinks causes excess caffeine consumption and leads to a host of additional health issues. It is essential to understand that the instant alertness from an energy drink comes from excess amounts of caffeine and sugar. An eight-ounce cup of coffee contains 100 milligrams of caffeine, as does eight ounces of the average energy drink. However, the average energy drink is 16 to 24 ounces and contains 200 to 300 milligrams of caffeine per can.
When the caffeine content in the energy drink is combined with sugar (an average of 15 teaspoons, or one-third cup, per 16-ounce serving), trace B vitamins, and carnitine (an amino acid purportedly pumps up endurance and promotes fat burning. Most people only need extra carnitine if deficient (which is rare), and more than 3 grams a day can lead to stomach upset and possibly seizures. The combination of ingredients in energy drinks can lead to high blood pressure, depression, and cardiac arrhythmia. As of 2014, 34 deaths and 56 serious health events linked directly to energy drink consumption have been reported by the Food and Drug Administration. This may seem like a small number, but consider the unreported cases of high blood pressure complications, anxiety, cardio arrhythmia, and depression that have roots in overconsumption of energy drinks.

High blood pressure affects the ability of the arteries to open and close. When your blood pressure rises, the muscles in the artery wall respond by pushing back harder. This enlarges the arterial walls and makes the arteries thicker. Thicker arteries reduce the amount of blood that can pass through them. Over time, high blood pressure leads to heart failure, kidney failure, stroke, dementia, and more. For a complete list, click here.
Depression associated with energy drink consumption is caused by a rise in the brain chemical norepinephrine. As norepinephrine increases, negative feelings, distrust, and the desire to fight or flee from unpleasant situations increase. In addition, anxiety rises. “In previous research, we found that energy drink consumption increased blood pressure in healthy young adults,” explained first author and Mayo Clinic cardiology fellow Anna Svatikova. “We now show that the increases in blood pressure are accompanied by increases in norepinephrine, a stress hormone chemical, and this could predispose an increased risk of cardiac events — even in healthy people.”
Heart rhythm problems (heart arrhythmias) occur when the electrical impulses that coordinate your heartbeats do not work correctly, causing your heart to beat too fast, too slow, or irregularly. The excess caffeine and sugar in energy drinks can contribute to abnormal heart rhythms.
Ask yourself if the energy drink is really worth the risk. There are so many healthier ways to increase and sustain your energy. Practice getting 7-8 hours of sleep each night, and improve your diet by including lean protein and smart carbs like almonds, cheese, and Greek yogurt. While working, at home, or on the job, take a short walk (5-10 minutes) every 1.5 hours. Take naps when you can (there is nothing like a 20-minute power nap.
Get creative, boost your energy, and improve your overall health by ditching instant energy and focusing on renewable, sustainable energy.
