Instant coffee is not recommended to you personally Although you drink 300ML of instant coffee, its caffeine content is high. Because instant coffee is generally made from Luo basta coffee beans, Robusta coffee beans are cheaper than better Arabica coffee beans, but the caffeine content is about 3%~4%, which is relatively high, so its economy is self-evident for instant coffee merchants. The content of good Arabica coffee beans is generally around 1.5%. The former is refreshing, but there are many additives. The latter is also refreshing and more beneficial to the body. In my coffee shop, Robusta coffee beans are not used in principle, because letting customers consume too much caffeine at one time will make people who want to taste coffee but are not addicted to it feel uncomfortable and uncomfortable, and they will soon become dependent on coffee after drinking more than a few times. In fact, to put it bluntly, the function of the human body has produced a dependence on caffeine.
It is best to drink freshly roasted, ground and brewed coffee. Coffee has a refreshing effect. I suggest you make a cup of breakfast in the morning, drink it before class at noon, and drink it before self-study at around 7 pm. And I suggest you serve 120~ 180ml arabica coffee at a time. Drinking coffee too late at night will make your sleep quality very bad. If the quality of sleep is not good, the learning efficiency of the next day will not be much higher. After a long time, it will easily become a vicious circle. Hehe, everyone has been there ~
You need your body to learn ~
I wish you good health and academic success.
