Basic knowledge of Coffee Why can coffee wake people up?

The secret is caffeine. Modern medicine has proved that it can stimulate the central nervous system, accelerate the speed at which people perceive the surrounding environment, and improve people's response and understanding ability. it can indeed bring spiritual pleasure, which is different from alcoholic pleasure. It is continuous, rising, steady, and does not have the attenuating effect of reaching the peak of pleasure like alcohol. Since the 17th century, Europe has entered an era of rationalism, which is not only reflected in philosophy, but also in all aspects of daily life, which is an important feature of civic spirit. In the Middle Ages, ordinary people mainly sold physical labor outdoors in exchange for food and clothing. after entering the civil society, the nature of the work of workers began to change in the 17th century, in addition to simple manual labor, there has also been more and more technical and intellectual labor. The ideal state of work is expected to be as punctual and accurate as clocks and machines, fatigue and laziness, which were common in medieval times, were declared blasphemous and illegal, such as the inevitable failures of the body as a tool. Coffee, like motor oil, can dispel emotions that interfere with work in the body's machine, keep the brain awake, and maximize the enforcement of Puritan ethics in the individual's body.

The citizen class, especially artists, is different from farmers and pure manual workers. They often work indoors and sit mainly when they work, a feature that remains unchanged today. The significance of this postural change seems to be underestimated. First, it makes it possible for labor to cross the physiological boundaries of manual labor, making it possible to work as long as possible, which is tantamount to stipulating that people's drinks must be anti-alcoholic; second, the indoor environment allows labor to ignore weather factors, ensuring continuity to the greatest extent, while providing hot water, utensils and even space necessary for drinking coffee. Under such working conditions and Puritan ethics, it seems immoral not to drink coffee.
