Two elements that are good for brain health-caffeine and coffee aroma
A small cup of black coffee can quickly awaken the brain, in the wonderful aroma of coffee, brain fatigue immediately reduced, from the original chaotic state into a clear sky, refreshing and pleasant. After the entrance of a cup of espresso or hand-brewed coffee, it can not only meet our taste needs, but also relieve brain fatigue, promote nerve excitement and improve brain work efficiency. Maybe this is one of the reasons why coffee has become a worldwide drink. So, what ingredients in coffee can have such a magical effect?
Coffee and caffeine.
The caffeine in coffee can relieve fatigue, promote nerve excitement, and thus improve mood. Of course, the time at which these effects of caffeine begin to take effect after coffee is drunk and how long it lasts in the human body varies from person to person. Therefore, some people are highly sensitive to coffee, while others drink 5 cups of coffee a day, 7 cups of coffee, 8 cups of coffee and even countless cups of coffee a day. According to the study, it is found that caffeine begins to take effect about 10 minutes after intake, and the duration of action in the body is 2 Murray for 3 hours. Relatively speaking, the effect and time of action in males is higher than that in females. Another new study shows that decaf can also have an effect, but for a short time.
Coffee and coffee smell.
Drinks containing caffeine include black tea, green tea, cocoa and other drinks, but the most well-known one is coffee. Why? This has something to do with the strong aftertaste left in the brain after drinking coffee.
The aroma of coffee is so strong that even people who don't drink coffee like to feel it. Recently, in some shopping malls, professional coffee shops have begun to appear in the hotel lobby, in which a very important role is to attract customers through the aroma of coffee.
Caffeine, which can relieve fatigue, contains a variety of flowers and substances such as ether, carbonic acid, ammonia and more than 20 trace elements, which interact with each other to produce a strong coffee aroma and charming flavor. A Japanese university has measured blood volume to study the effect of coffee on the brain. The results show that the amount of blood in the right part of the brain that regulates pleasure increases when people smell coffee. Even if you don't drink coffee, you can increase your sensitivity to pleasure by just smelling it, thereby increasing your mood and concentration.
Of course, we can also smell the aroma of instant coffee when making instant coffee, but it is not the original aroma of coffee but the addition of essence and cream, so instant coffee is not only not good for people but also harmful to health. If you compare instant coffee with freshly roasted coffee, you can easily tell the difference between their aroma, just as the difference between fresh fruit and fruity aromatics is as obvious. In addition, in order to attract customers with the smell of coffee, but there are not so many fresh coffee beans, some hotels, cafes and other places keep spraying coffee-scented air fresheners, which can be used as air fresheners, but it is not advisable to confuse customers' sense of smell.
