Recently, Professor A. P. Smith of the University of Bristol (University of Bristol) in the United Kingdom published his ten-year talk about the imagination of coffee on the brain, especially its effect on discrimination and mood. Measure their discrimination and alertness for 30 minutes before and after drinking coffee. Smith found that after drinking a cup of coffee, they become more alert and more focused. Professor Smith said that coffee can really refresh you, especially if you don't get enough sleep, if a cold makes you sleep badly, or insomnia, and you have to concentrate on your work or exams during the day, then drinking a cup of coffee will certainly boost your alertness and tide you over. And coffee will stay in the body for three to five hours, so coffee has a long-term refreshing effect. Further experiments have found that the average person can absorb 300 milligrams of caffeine (about three cups of brewed coffee) a day and have a positive imagination for a person's alertness and mood. However, more than 400 milligrams (four cups) of caffeine will bring side effects, such as mood deterioration, irritability, aggression and causing trouble.
