Chew gum to boost your alertness and concentration and to reduce your daily stress levels during repetitive or intense tasks.

The concept of chewing to remain alert and better manage mental pressure is a surprisingly well-documented subject. For example, a meta-analysis of 21 studies published by Miquel and his team (2019) highlighted a significant statistical link between chewing and improved sustained attention. Regarding serenity, a randomized controlled trial (RCT) led by Andrew Scholey (2009) revealed that chewing gum reduced cortisol (the stress hormone) during demanding cognitive activities. Furthermore, another meta-analysis of controlled trials (2022) confirms that regular chewing contributes to an overall decrease in daily anxiety and tension. Although this action does not replace proper recovery, it mechanically stimulates blood flow to brain areas associated with alertness. It is therefore a simple habit, widely validated by research, for providing a boost to one's performance.
