Energy drinks are those consisting of sugar and stimulant substances such as caffeine. Therefore, these drinks are used for energy boost up in routine life. However, these can be harmful if not used in a balanced proportion. The ingredients of energy drinks may have potential side effects as well.
How stimulants work?
Stimulants in energy drinks such as caffeine hijacks and mimic the natural brain function and hormonal release. The stimulant molecules attach to the adenosine receptors in brain, pushing them off. This results in feeling of mental alertness. Some researcher hypothesizes that combining a stimulant such as caffeine with electricity will allow to escape and remodel the natural sleep pattern in humans.
Taking an energy drink make you feel active. The stimulants in them activates the brain cells that send message to pituitary gland. This results in substantial amounts of stress hormones including cortisol and adrenaline. Consequently, the body responds the same way as in some imminent danger and one feels more active.
