Several studies suggests that chewing gum helps individuals maintain their focus during long tasks. The effects differs depending on short term stress (studying for an exam) or long term stress (having a stressful semester). The benefits of the gum are strongest after working on a task for a long time. Researchers have measured brain waves and found that chewing gum alters certain patterns associated with staying alert. The brain action potential P300, linked to paying attention, occurs faster after chewing gum. Brain scans indicate increased activity in areas responsible for alertness and decision-making when chewing gum and doing attention task simultaneously.
Research has shown that chewing gum increases blood flow to the brain, which improve cognitive performance and memory. The muscles in our jaw and face are activated when chewing gum, which sends signals to the brain that trigger increased blood flow to the head. This surge in blow flow brings a fresh supply of oxygen and nutrients to the brain, enhancing its overall function. Additionally, the act of chewing gum stimulates the production of saliva, which contains enzymes that break down food particles and aid in digestion. This process supports the body's nutritional needs and maintains optimal brain function.
The repetitive motion of chewing also stimulates the production of certain neurotransmitters, such as dopamine and serotonin, which are associated with improve mood and focus. It can also serve as a distraction from anxious thoughts or situations, allowing individuals to focus on the task at hand.
Scientists have tested the theory of whether the physical act of chewing causes these effects by using gum without flavor or smell. The results suggest that the act of chewing is important. The rate at which the gum is being chewed was also tested. However, chewing more vigorously or increasing resistance does not create stronger effects on memory. Although, since chewing gum can stimulate arousal, such as increasing the heart rate, during attention tasks, it is more plausible that chewing more vigorously could have a greater effect on attention. Overall, research indicates stronger benefits of chewing gum to aid with long-term, ongoing stress rather than immediate, short-term stress.

Great post, Alex! I remember in elementary school, my teacher had us chew gum for every test that we took. I loved test day because I got to chew gum, but yet again, there were some loud smackers in that class that made it hard for me to concentrate. I did not know that it stimulates the production of neurotransmitters and that the action potentials for attention occur faster! I did hear some bad outcomes for chewing gum for a prolonged amount of time (https://www.health.harvard.edu/staying-healthy/is-constant-gum-chewing-a-bad-idea), which include a possible TMJ or cavity formation.
ReplyDeleteDo you think there should be a 'time limit' for chewing gum? But also a real question, do you think they have some cherry gum so that I can put it in my cherry lunchbox?
Hi Alex this was a great breakdown! I like how you highlighted both the physiological and cognitive mechanisms behind chewing gums effects. It's interesting that something as simple as chewing gum can influence brain activity, from increasing blood flow and oxygen to speeding up the P300 response associated with attention. The distinction you made between short term and long term stress was interesting as well. I know you mentioned flavorless and gum without any scent but I wonder if there's a difference between like mint or sweet flavored gum and how it would impact focus or alertness?
