Although around 2000 studies are carried out every year on everything to do with coffee, the small coffee bean has not yet been fully researched. Their chemical composition is extremely complex and their effect on the human body depends on many different factors. What is certain is the stimulating effect of caffeine on the circulatory system. The blood vessels dilate, the heart rate increases, and the blood flow to all orange improves. Caffeine also affects our breathing. This is accelerated and the bronchial vessels widen.
But the effect people appreciate most about coffee is that on our brain. Here, too, the caffeine leads to better blood circulation. This makes you feel more lively, your ability to concentrate increases, and even your ability to concentrate increases. And that explains why most coffee drinkers do not want to go without their favorite drink, especially in the morning. However, the effect is not immediately apparent. The coffee only stimulates the organism after a good half an hour.
Coffee can also be a small digestive aid. Drunk after eating, it stimulates the production of gastric acid and bile secretion - the stomach and intestinal tract get going.
However, you don't need to be afraid that you will become addicted to it after enjoying a long coffee. The black bean does not contain any addictive substances - however, you can subjectively perceive your own drinking habits and preferences as addiction.
However, a thoroughly positive picture cannot be drawn, especially when coffee is drunk in large quantities. This can lead to palpitations, high blood pressure or tremors, sometimes also to anxiety attacks. Those who are sensitive to caffeine suffer from sleep disorders above all. The acidity of the coffee can cause stomach problems. People with high blood pressure, pregnant women and nursing mothers should be more reluctant to consume it.
