Probably, each of us knows that since ancient times coffee was accepted to be served along with water. Our ancestors washed down all the coffee drinks with water. But now, almost nobody follows this tradition, but in vain ...
Why coffee should be washed down 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 that entails certain consequences. Such consequences must be known to people counting on the invigorating effect of coffee.
Coffee beans consist of two parts: the casing containing caffeine, and the inner part, in which there is the so-called theobromine alkaloid.
When we drink whole-grain coffee, caffeine and theobromine enter our body at the same time, but they start to act in turn. First comes into effect caffeine, which gives you a charge of vivacity, you begin to feel a surge of strength and energy.
This is 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 goes down, which gives the feeling of cheerfulness. But it does not last long, in about 25 minutes, the effect of caffeine on the body ends.
Following caffeine in the reaction with the body comes theobromine, which has absolutely the opposite effect. Instead of charging you with energy, it helps to relax. Approximately half an hour after you have drunk a cup of coffee, a feeling of fatigue comes, you again want to sleep. Also, many have unpleasant sensations in the kidney area.
If you drink coffee and are concerned for your health, after every sip of this drink you should take a sip of water to avoid disturbance of blood flow in the kidneys.
Also, water weakens the effect of caffeine, so if you start drinking it with coffee, notice that the heart will not beat like mad.
An interesting fact about instant coffee
In soluble coffee, there is virtually no caffeine, it is made from the inside of the coffee beans, which contains theobromine. The outer shell of coffee beans is used for the manufacture of medicines and power engineers. Therefore, coffee drinks based on instant coffee are not invigorating, but are driven into sleep.
After an instant coffee, you will feel tired for about an hour. To reduce this time, doctors recommend drinking such coffee with water. Better yet, drink strong black tea instead of coffee. Caffeine in it is enough, but the theobromine is completely absent.
Love of coffee is special, it's very difficult to give up this drink. If you are a real cocktail, do not stop pampering yourself with your favorite coffee drinks, just wash them with water to minimize their impact on your health.
