Tuesday, February 8th, 2011


A Swinburne University researcher and the Wrigley Science Institute have found that gum chewing can lower stress levels and improve performance. For the study, participants performed a battery of multitasking activities while chewing gum. Among the findings? Gum chewing . . .

  • Relieved anxiety. During mildly stressful activity, chewing gum was found to reduce anxiety in gum-chewers by 17 percent when compared to nongum-chewers. During moderately stressful activities, the reduction rate was 10 percent.
  • Increased alertness. During mild stress activities, gum-chewers were 19 percent more alert than nongum-chewers. During moderate stress, gum-chewers were 8 percent more alert.
  • Reduced stress. Salivary cortisol (a physiological stress marker) levels were 16 percent lower in gum-chewers during mildly stressful activities; during moderately stressful activities, the difference was 12 percent.
  • Improved performance. Gum-chewers improved mean performance by 109 percent during mildly stressful activities, and 67 percent during moderately stressful activities, when compared to nongum-chewers.
