Results revealed that gum chewers experienced significantly higher levels of alertness and lower levels of state anxiety, stress, and salivary cortisol. The chewing gum condition was also associated with better performance on the multitasking activities. Improved cerebral blood flow during gum chewing was cited as a possible explanation for these findings.
