Find it hard to stay focused? Try some mocha coffee.

Psychological researchers at the University of Georgia and Clarkson University in the United States recruited volunteers to drink cocoa, caffeinated cocoa, non-cocoa coffee and placebo drinks that contain neither cocoa nor caffeine for a year. The experiment was conducted in a random, double-blind way, that is, neither the researchers nor the subjects knew what kind of drink the subjects would be given. After drinking a hot drink, the subjects were also tested on their cognitive function and emotional level. The results showed that subjects who drank a mixture of cocoa and caffeine performed best.

Coffee is refreshing, Reqiao relieves anxiety, and drinking them together can help prolong attention span, the researchers reported in the Journal of Biomedical Center Nutrition.

"this is an interesting study," said Ali Blarney, a professor at Clarkson University who participated in the study. The test results clearly show that the combination of cocoa and caffeine is a good choice for students and others who need to concentrate for a long time.
