Quietly, chewing gum has moved from being a casual habit to a behavior of scientific interest, especially in high-pressure situations such as competitive sports. In studying performance patterns, researchers have found that the simple, rhythmic act of chewing can influence cognitive function, attention levels, and emotional stability-explaining why so many athletes are seen chewing gum during matches.
Chewing gum diminishes stress and controls cortisol.
Studies investigating chewing and stress responses indicate that rhythmic jaw movements may stimulate brain regions related to relaxation and arousal, a phenomenon resembling the body's response during feeding, whereby it primes the brain to understand that this activity is a sign of safety.

This, in turn, tends to lower cortisol, which is the main stress hormone and, in so doing, improves mood and promotes physiological steadiness.
Increased blood flow to the areas of the brain responsible for concentration further heightens mental clarity. Flavored gum offers a sense of sensory grounding, helping people remain centered when they feel stressed or are engaging in long periods of mental focus. Many individuals who use gum in their studying or employment feel much more composed and better able to concentrate on activities that require prolonged concentration.
Why athletes chew gum during matches?
A new video posted by Gurjit Kaur, a fitness coach, on Instagram reignited public interest in the phenomenon of gum chewing among athletes. Her explanation thus corroborated previous behavioural research identifying the habit of chewing as maintaining an alert yet composed mental state during fast-paced games.
A study published in the Scientific Journal of Sport and Performance notes that chewing can moderate performance disruptions caused by stress because of a number of benefits for players:
Lower levels of cortisol help in enabling athletes to be calm in uncertain or highly demanding situations.
Improved cerebral blood flow supports quicker reactions and faster processing of on-field cues.
Steady levels of arousal avoid dips in focus during long or intense matches.
Controlled chewing is associated with slight gains in reaction speed and cognitive endurance.
Many professional athletes also chew gum as a behavioral anchor, a steadying rhythm that can keep them level when the pressure spikes.
A simple habit with measurable impact
Growing interest in chewing gum reflects a broader shift toward adopting small daily habits that support mental clarity and emotional wellbeing. For many, it is a gentle substitute for caffeine or stress-induced snacking that is easy to carry around, quick to use, and effective across various settings.

The steady rhythm of chewing is a way to maintain engagement, reduce tension, and think more clearly over long periods of time when working or engaging in physical activities. For many, it has now become a subtle yet surefire way to keep focused, composed, and mentally razor-sharp.
