Chewing gum may improve focus and reduce stress by activating specific brain regions

Chewing gum activates brain regions linked to attention and stress regulation, potentially explaining its long-held use for focus and calm. A recent review of brain imaging studies found chewing alters activity in areas associated with alertness and emotional control, offering a biological basis for its perceived benefits. While the effects are often brief and limited to mild stress, research suggests gum chewing can modulate brain function beyond simple motor control.
