Why do I need to drink coffee with water
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. People who are counting on the invigorating effect of coffee need to know about such consequences.
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 enters into action, which gives you a boost 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 use the toilet. In all other organs, the pressure decreases, from which a feeling of vigor comes. But this does not last very long, after about 25 minutes the effect of caffeine on the body ends.
Following caffeine, theobromine, which has the exact opposite effect, reacts with the body. Instead of energizing you, it promotes relaxation. About half an hour after you have a cup of coffee, a feeling of tiredness comes, you want to sleep again. Also, many have unpleasant sensations in the kidney area.
If you drink coffee and care about your health, after each sip of this drink you should take a sip of water to avoid impaired blood flow in the kidneys.
Water also weakens the effect of caffeine, so if you start to drink coffee with it, you will notice that the heart will not beat like mad.
An interesting fact about instant coffee
There is practically no caffeine in instant coffee; it is made from the inside of coffee beans, which contains theobromine. The outer shell of coffee beans goes to the manufacture of medicines and energy. Therefore, coffee drinks based on instant coffee do not invigorate, but are driven into sleep.
After instant coffee you will feel tired for about an hour. To reduce this period of time, doctors recommend drinking such coffee with water. Better yet, 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.
