Chewing Gum Improves A Person's Mood

Chewing gum produces a number of benefits that are generally observed and not context-dependent.

Chewing gum was associated with greater alertness and a more positive mood.

Reaction times were quicker in the gum condition, and this effect became bigger as the task became more difficult.

Chewing gum also improved selective and sustained attention.

Heart rate and cortisol levels were higher when chewing which confirms the alerting effect of chewing gum.
