Why coffee is so stimulating

Coffee in a cup

Most Germans decide daily for their cup of coffee - after all, we drink 73 million cups a day for Germans. Each cup of coffee contains 100 mg of caffeine. When we enjoy the hot beverage in moderation, coffee has very positive effects.

In the 17th and 18th centuries, coffee slowly but surely prevailed in Europe. First coffee was drunk for breakfast, later more and more with the other meals. The popularity of coffee is based mainly on its stimulating effect. This effect of coffee can be attributed essentially to the caffeine and chlorogenic acids contained.

Caffeine content in coffee

A coffee bean contains between 0.8% and 2.5% caffeine. The caffeine content in coffee is also determined by the contact time of the water with the powder. In the usual amount - no more than four cups a day - there is no health risk. Despite all efforts, it has not yet been possible to establish a complete balance of all components of the coffee, because its chemical composition is extremely complex and depends on a variety of factors.

Secured is the stimulating effect for the circulation. The blood vessels are dilated, the heart rate is increased and the circulation of all organs is improved. Caffeine also affects our respiratory center - it accelerates breathing and expands the bronchial vessels. Caffeine also acts as a diuretic and leads to increased urination (diuretic effect). In general, one can say - coffee boosts the entire metabolism. In addition, it increases the calorie consumption, but is no problem for the figure with zero calories.

Coffee makes you happy

The coffee bean has an amazing effect on our gray cell: the brain circulation is increased - and thus the concentration. The speed of reaction and receptiveness of our brains are also increasing. Coffee is a "wake-up" - after a cup of coffee we are again more attentive and concentrated than before. Coffee makes you more creative, intelligent and enduring, which does not necessarily mean that it robs us of sleep. So, some of two cups get better in the late afternoon, while others make only one cup drowsy.

The big advantage: there is no caffeine addiction in the sense of an addiction. The stimulating effect is about 30 to 45 minutes after drinking coffee. Recent studies have shown that the best effect is to consume the caffeine in small doses throughout the day rather than in a large cup in the morning.
