Why do you need to drink coffee
It turns out that this ritual is not just one of the inexplicable rules of coffee etiquette, it is a fully justified action, which entails certain consequences. Such consequences should be known to people who rely on the invigorating effect of coffee.
The coffee bean consists of two parts: the shell, which contains caffeine, and the inside, which contains the so-called alkaloid theobromine.
When we drink whole-grain coffee, caffeine and theobromine enter our body at the same time, but they begin to act in turn. First, caffeine comes into action, which gives you a charge of energy, you begin to feel a surge of strength and energy.
This happens due to the fact that the vessels in all organs of your body, except the kidneys, begin to narrow. In the kidneys, the vessels, on the contrary, expand, due to which the pressure rises, and you want to go to the toilet. In all other organs, the pressure decreases, from which comes a feeling of cheerfulness. But it does not last very long, after about 25 minutes the effect of caffeine on the body ends.
Following caffeine, theobromine, which has a completely opposite effect, reacts with the body. Instead of charging you with energy, it promotes relaxation. About half an hour after you drank a cup of coffee, you feel tired, you feel like sleeping again. Many also have discomfort in the kidney area.
If you drink coffee and bake your health, after each sip of this drink you should take a sip of water to avoid disruption of blood flow in the kidneys.
Water also weakens the effect of caffeine, so if you start drinking coffee with it, you will notice that the heart will not beat like a rabid one.
Interesting fact about instant coffee
There is almost no caffeine in instant coffee, it is made from the inside of a coffee bean that contains theobromine. The outer shell of the coffee beans is used to make medicines and energy products. Therefore, instant coffee-based coffee drinks are not invigorating, but rather sleepy.
After instant coffee you will feel tired for about an hour. To reduce this period of time, doctors recommend drinking this coffee with water. And even better - drink strong black tea instead of coffee. There is enough caffeine in it, but theobromine is completely absent.
The love of coffee is special, it is very difficult to refuse this drink. If you are a real coffee lover, do not stop pampering yourself with your favorite coffee drinks, just drink them with water to minimize their impact on your health.
