Benefits of chewing gum
A new study used brain scans to see which areas of the brain were active as study participants responded to on-screen performance tests. Some of the participants were chewing gum while others were not.
Japanese researchers report chewing appeared to boost thinking and alertness. Reaction times among the gum chewers were up to 10 percent faster.
The researchers suggest it’s because the act of chewing leads to improvements in blood flow to the brain.
