Drinking caffeine is not a problem — but why avoid energy drinks?
Energy drinks contain a lot of caffeine. Many people consume caffeine daily, but the amounts found in energy drinks are dangerously high.
Figures show that some energy drinks contain up to 500 mg of caffeine per can. By comparison, a cup of coffee contains between 77 and 150 mg. Everyone knows that you shouldn’t overdo it with coffee, yet the aggressive marketing of energy drinks tries to convince us that energy drinks are an essential part of life.
Caffeine is a diuretic, increases body temperature, nervousness, anxiety, insomnia, irritability, and disrupts heart rhythm. Scientifically, there is little evidence for any performance-enhancing effects. It may temporarily increase alertness, but mainly in cases of sleep deprivation. Lastly, caffeine can be addictive and may contribute to maintaining other addictions.
