Substances that are able to impart vivacity and increase efficiency, have enjoyed success in man since the earliest times. Most often they were contained in various plants and their parts: in Asia these were the leaves of a tea tree, in America - fruits of guarana, in Africa - grains of coffee. Europe happily borrowed the traditions of consumption of the first "power engineers", simultaneously developing their own methods.
In the era of high technology, a series of new "elixirs of vivacity" - the so-called energy drinks, combining efficiency, ease of use and balance of the composition, in any case, so say the companies producing them. Let's see how their statements correspond to reality.
Benefit and harm of power engineers
Most advertising companies position energy sources as a source of cheerfulness, the use of which makes it possible to do almost impossible. However, this is not entirely true - energy drinks, like other stimulants, simply open up access to the hidden reserves of the body, reserved for a rainy day. However, it is worth giving power engineers the due, they act much faster than tea or coffee , and the effect of using them lasts about 4-5 hours, unlike 2-3 after a cup of strong coffee. The truth and side effects from their use will be much more powerful, because we take energy away from our own body, and for this we will not thank you. Therefore, before "robbing" the body, evaluate how necessary it is, because the emotional and physical recovery inevitably leads to a reckoning that at best will result in fatigue and mild depression, and at worst in problems with the cardiovascular system, chronic headaches and sleep disturbances. Therefore, despite the effectiveness of these drinks, frequent use of power engineers can cause significant harm to health.
As one of the pluses of power engineers is often called - the convenience of their use. With this it is difficult to argue - a small jar of such a drink can be taken both on the road and into the reading room. They do not need to be prepared for the use process, it is convenient to store. In terms of convenience, energy drinks are clearly ahead of traditional stimulants.
As for the balance of the composition - this, at least, is a very controversial issue. First, their main component is caffeine - it is in the energy sector from 100 to 350 mg / l, while that without harm to health, a healthy adult can consume no more than 250 mg of this substance per day. That is, an overdose of caffeine to you can provide only a couple of cans of especially energetic energy specialists, and it is not only that it is harmful to health, but it is also expressed by very unpleasant symptoms:
- tremor of extremities;
- increased pressure;
- nausea;
- confusion of consciousness;
- tachycardia.
In addition, in addition to useful additives (vitamins, amino acids ) in most energo-workers there are dyes, as a rule, artificial flavors also not natural, but also preservatives.
Proceeding from all written above, drinking energy should be cautious, realizing what possible harm can be obtained from their use.
