The main function of coffee is refreshing. That's because coffee contains caffeine that stimulates the central nervous system, so it will make people excited. A small amount of caffeine is really beneficial to relieve muscle fatigue and has diuretic effect. But as long as it is excessive, it will have adverse effects on the body.

I heard from a friend that a child was often sleepy when he was in high school. However, due to the pressure of studying in high school, she doesn't have enough rest time, so she will drink coffee to refresh herself. She is so persistent that she drinks it every day. Later, I heard that the child was a little addicted. As long as she doesn't drink it at that time of day, she will feel uncomfortable. The truth of this matter needs further study, but it is not impossible. After all, coffee does have addictive substances.

But coffee is not without its merits. It is really good to drink it in small quantities.

Working hard one day and sleeping late will lead to poor spirits the next day. If the work task is heavy the next day, you can have some coffee to refresh your mind, relieve fatigue and ensure your work energy.

Appropriate amount of coffee can play a role in saving, and can improve liver function, diuresis and dehumidification, and relieve constipation. Therefore, as long as it is well controlled, coffee can also be helpful to the body.

Existence is reasonable, and the environment of coffee shops is generally good. During tea time, white-collar workers can talk about work in the coffee shop. Quiet but not tense environment is conducive to talking about work or relaxing, or couples have nothing to do, you can go to the coffee shop to talk. Occasionally melodious music atmosphere is most suitable for dating.

Therefore, it is best to drink coffee often and only when necessary.
