Drinking a cup of coffee and chocolate brewed together may improve your attention span, according to a new study.
According to researchers from Clarkson University in New York and the University of Georgia, coffee and chocolate is set to improve your attention span and help you fight the lethargy that comes along with late hours.
Caffeine is the most widely used drug in the world and most people don’t even realize it’s a drug. The reason it wakes you up and makes you feel more alert and focused is because it stimulates your central nervous system.
Study show that the combination of coffee and chocolate can increase mental focus and concentration.
Caffeine blocks the action of adenosine, a molecule which directs our brain to feel tired.
“Cocoa increases cerebral blood flow, which increases cognition and attention. Caffeine alone can increase anxiety. This particular project found that cocoa lessens caffeine’s anxiety-producing effects, a good reason to drink mocha lattes!” said Ali Boolani of Clarkson University in the US.
Participants were made to consume brewed cocoa, cocoa with caffeine, caffeine without cocoa, and a placebo with neither caffeine nor cocoa.
They were then asked to do tests to evaluate both cognitive tasks and mood. Participants were asked to watch as letters flashed across a screen and note when an ‘X’ appeared after an ‘A.’ They also had to point out when odd numbers appeared sequentially and they were required to do subtraction.
“The results of the tests are definitely promising and show that cocoa and caffeine are good choices for students and anyone else who needs to improve sustained attention,” said Boolani.
The study was published in the journal BMC Nutrition.
