Coffee is a popular drink that has benefits such as refreshing the mind and improving work efficiency, but it is also a double-edged sword. Excessive coffee consumption may lead to side effects such as insomnia and palpitations.

When enjoying the benefits of coffee, you should drink it in moderation and avoid over-dependence.

In the busy modern life, coffee has become an indispensable partner for many people. It can not only refresh the mind, but also serve as a medium for social occasions. Does this drink that has been with us for many years really have only benefits? No, the impact of drinking coffee is like a double-edged sword, which brings both benefits and side effects. Let's take a deeper look at the benefits and side effects of drinking coffee.
