Caffeine and the central nervous system.

What is the reason for the increase in human activity after consuming caffeine? Caffeine has the ability to replace adenosine - a substance that acts as a rejuvenator of the nervous system and thus protects the body from overloads. However, this is only a visible substitute. In fact, the same effect as adenosine, caffeine does not have, thus giving the body the ability to work without restrictions. But you understand that at this pace our body and nervous system are not able to work endlessly, consuming their resources. Therefore, the body synthesizes a new portion of adenosine, causing you the appearance of fatigue and, accordingly, the desire to drink more caffeine to overcome this fatigue. It is from here that originates from the dependence on coffee, which is so much talked about in the media.

Caffeine and heart.

Forcing our cells to work more actively, caffeine causes a stressful situation in the body. And at such times the body begins to produce adrenaline. Surely you know about what adrenaline is and imagine the principle of its work in the body. It is because of it that the use of caffeine, or containing a large amount of caffeine guarana, forces the heart to beat harder, expands the pupils, and also improves the reaction speed and enhances sweating. By the way, it is guarana that is often added to the power industry. Caffeine contained in it, works a more even background and for a longer period of time.

Caffeine and fat burning.

The appearance of caffeine in the body speeds up the overall metabolism, causing the number of fatty acids from the subcutaneous fat to increase in the blood. However, do not forget that the transportation of these fatty acids to the cells where they are utilized occurs only with the help of l carnitine. So if you plan to use caffeine fat burner, then you should buy l carnitine to really feel the desired effect.

So, let's sum up:

1. Athletes should consume caffeinated drinks only before training. If you need to raise the general tone of the body on a normal day, then after the action of the energy it is necessary to give the body a rest to restore the balance of energy and adenosine.
2. Think about the fact that each time increasing the dose of caffeine, you are as if borrowing from the body some amount of energy that will need to be returned in full, and not try to drive yourself into a vicious circle of endless increase in the level of consumed caffeine. Because In the end, you can get insomnia, chronic fatigue and irritability.
3. Do not buy energy with guarana if you have heart disease, a vegetative system, or the central nervous system.
