Does gum improve concentration? After being very curious about this topic, I decided to do some research about it. According to Scientific American, “The researchers say that gum increases the flow of oxygen to regions of the brain responsible for attention. More oxygen can keep people alert and improve their reflexes. Research also shows that you won’t get the same effect by just pretending to chew gum.” They also say, “Those chewing gum also maintained focus longer during the exercise.” These statements prove that chewing gum helps people remain concentrated within any situation. So if your having a troubled time focusing, throw a piece of gum in your mouth.
