New research finds chewing gum may help reduce stress

Study to be presented at the 2008 10th International Congress of Behavioral Medicine

WHAT: "An investigation into the effects of gum chewing on mood and cortisol levels during psychological stress," to be presented at the 2008 10th International Congress of Behavioral Medicine, found that chewing gum helped relieve anxiety, improve alertness and reduce stress among individuals in a laboratory setting.* The study examined whether chewing gum is capable of reducing induced anxiety and/or acute psychological stress while participants performed a battery of 'multi-tasking' activities. The use of chewing gum was associated with higher alertness, reduced anxiety and stress, and improvement in overall performance on multi-tasking activities.

WHO: Andrew Scholey, Ph.D., professor of Behavioral and Brain Sciences, Swinburne University in Melbourne, Australia led the research study and can discuss the effect of chewing gum on stress relief and focus and concentration.

Gilbert Leveille, Ph.D., executive director, Wrigley Science Institute, will also be available to discuss research on the benefits of chewing gum related to stress relief and alertness and concentration in addition to other areas including weight management and oral health.

WHEN: Study to be presented orally on Saturday, August 30 at Rissho University in Tokyo, Japan at the 10th International Congress of Behavioral Medicine.

STUDY BACKGROUND:

In the 40-person study of gum chewers averaging an age of 22 years old, performed on the Defined Intensity Stressor Simulation (DISS), a multi-tasking platform which reliably induces stress and also includes performance measures, while chewing and not chewing gum. Anxiety, alertness and stress levels were measured before and after participants completed the DISS.
