Energy Drink
Energy drinks are beverages whose producers advertise that they "boost energy". These advertisements usually do not emphasize energy derived from the sugar and caffeine they contain but rather increased energy release due to a variety of stimulants and vitamins
Many people rely on energy drinks and medications to keep them awake longer. When you cheat your body of the sleep it needs, your health will suffer. Your risk for stroke, diabetes, weight gain, heart attack and pre-mature aging increases.
A variety of physiological and psychological effects have been attributed to energy drinks and their ingredients. Two studies reported significant improvements in mental and cognitive performances as well as increased subjective alertness. Excess consumption of energy drinks may induce mild to moderate euphoria primarily caused by stimulant properties of caffeine and may also induce agitation, anxiety, irritability and insomnia.
During repeated cycling tests in young healthy adults an energy drink significantly increased upper body muscle endurance. It has been suggested that reversal of caffeine withdrawal is a major component of the effects of caffeine on mood and performance.
