Does Chewing Gum While Running Help

As a runner, I’ve often wondered about the potential benefits of chewing gum while running. Does it actually help, or is it just a myth? Let’s dive into this topic and explore the potential impact of chewing gum on a run.

The Potential Benefits

There are a few proposed benefits of chewing gum while running. Firstly, it is said to increase saliva production, which can help keep your mouth from becoming dry during a run. Additionally, some believe that the act of chewing gum can help alleviate feelings of nausea or stomach discomfort while running. It’s also suggested that chewing gum might provide a psychological boost by keeping your mind and mouth occupied, especially during long or grueling runs.

Scientific Evidence

While many runners swear by the benefits of chewing gum while running, the scientific evidence is somewhat limited. Some studies have shown that chewing gum can lead to increased saliva production, but whether this has a significant impact on hydration during a run is still up for debate. There’s also limited research on the potential psychological benefits of chewing gum while running, so it’s difficult to say for certain whether it provides a tangible mental boost.

Possible Drawbacks

On the flip side, there are a few potential drawbacks to consider. Chewing gum while running may lead to jaw fatigue, especially during longer runs. Additionally, some runners find that the act of chewing can be distracting or uncomfortable, especially when trying to maintain a steady breathing rhythm.

My Personal Experience

After experimenting with chewing gum during my own runs, I’ve found that it can be a hit or miss. On shorter runs, I’ve noticed that it does help keep my mouth from getting too dry, and it can provide a welcome distraction. However, on longer runs, I’ve experienced jaw fatigue and found that it’s more of a hindrance than a help. That being said, individual experiences may vary, and some runners may find that chewing gum significantly enhances their running experience.


At the end of the day, whether chewing gum while running helps is largely a matter of personal preference and individual experience. Some runners may find it beneficial for managing saliva production and providing a mental distraction, while others may find it distracting or uncomfortable. If you’re curious about the potential benefits, I’d recommend giving it a try during a few training runs to see how it feels for you. Ultimately, the impact of chewing gum while running is a personal and subjective matter.
