Coffee, a double-edged sword for the body

Coffee is a double-edged sword. It can refresh the mind, but it can also have a negative impact on physical health. Drinking coffee in moderation can stimulate the nervous system and improve work efficiency, but excessive drinking can lead to insomnia, anxiety and other problems. Caffeine may also affect the cardiovascular system and increase the risk of heart disease and high blood pressure. Coffee also contains a variety of antioxidants, and drinking it in moderation can help prevent certain diseases. Drinking coffee rationally and mastering the principle of moderation is the key to enjoying the benefits of coffee while avoiding health risks.

In busy modern life, coffee has become an indispensable partner for many people. A cup of coffee a day seems to have become the norm in urban life, but have you ever really understood the advantages and disadvantages of this dark drink?
