10 Minutes: Chew a Stick of Gum

Researchers from Australia and England found that in moments of stress, gum chewers felt less anxious and had 18 percent less cortisol (the stress hormone) in their saliva. "Chewing increases blood flow to the brain—which may make us feel more alert—and it may also distract us from stressors," says study coauthor Andrew Scholey, PhD, director of the Centre for Human Psychopharmacology at Swinburne University.
