Most popular energy drinks act as a sharp stimulus for an exhausted nervous system. They do not provide real energy but merely force the internal environment to urgently expend emergency reserves. Massive portions of synthetic caffeine combined with a huge amount of refined sugar cause a sharp spike in stress hormones.
This process leads to a short-term burst of vitality for a couple of hours, after which a deep crash inevitably follows: lethargy, irritability, decreased concentration, and an overwhelming desire for another serving. Regular use of such stimulants overloads the cardiovascular system and leads to chronic fatigue.
