Drinking coffee often has certain benefits, but we should pay attention to controlling the amount. Because coffee contains a certain amount of caffeine, it can stimulate the central nervous system, thus achieving the effect of relieving fatigue and refreshing. But drinking coffee often can produce a slight sense of dependence. For example, if the patient is temporarily stopped, it may cause slight fatigue and inattention, and may also affect the appetite and cause a decrease in appetite. Coffee can be drunk when staying up late, working overtime or being overtired. Usually, try to drink less or not.

Coffee can help us to refresh ourselves, improve nerve function and even have certain antioxidant effect. Studies abroad have found that one or two cups of coffee a day can help us improve our immune function and work efficiency, but many people like to add sugar and coffee partners when drinking coffee, which may lead us to consume too much sugar and trans fatty acids, thus affecting our health.

In addition, drinking too much coffee, such as more than six cups a day, may bring excessive nerve excitement, affect sleep and be harmful to health. Drinking too much coffee will also inhibit the absorption of calcium and easily lead to osteoporosis, so one or two cups of coffee a day is the best choice.
