Ronald Reagan, the 40th President of the United States, was a prominent political leader who led the end of the Cold War, revitalized the American economy, and displayed clear communicative leadership. As the head of a global superpower tasked with bearing the immense weight of national crises and crucial decisions, what was his secret to cognitive relaxation? 🍬
On Reagan’s Oval Office desk and boardroom tables, there was always a glass jar filled with colorful ‘Jelly Belly’ jellybeans. During tense US-Soviet summits or urgent national affairs meetings, whenever he felt cognitive rigidity setting in, he silently popped a small candy from the jar into his mouth. Slowly chewing the sweet piece momentarily slowed his cognitive pace and supplied glucose to his brain, relieving his heavy mental pressure.
Today’s post introduces the science behind President Reagan’s jellybean cognitive relaxation routine, showing how taste stimulation replenishes prefrontal cortex glucose and reduces stress.

1. Mastication and Sensory Substitution for Calming the Amygdala
Repetitive mastication (chewing) activates the trigeminal nerve in the brain, inhibiting the amygdala, which governs fear and stress. This stabilizes the pulse and rapidly lowers cortisol secretion.
At the same time, when a strong addictive craving strikes—such as the urge to smoke or binge on sweets—introducing a safe alternative sensory stimulus (like chewing jellybeans) into the mouth provides oral sensory substitution. This calms and stabilizes the brain’s dopamine reward circuit, helping to disrupt harmful automatic behaviors.
2. 3-Step Practical Routine for Modern Professionals
Prepare Alternative Chewing Items
Before cravings or stressful situations arise, prepare alternative items with chewy or crunchy textures in advance, such as sugar-free gum, sugar-free gummies, or a pack of nuts.
Perform Sensory-Focused Mastication
At the peak of anxiety or craving, place the chewing item in your mouth and slowly begin chewing, focusing on the movement and tension of jaw muscles and saliva secretion.
2-Minute Relaxation & Breath Tuning
Maintain chewing for 2 minutes while taking deep breaths. Relax bodily tension so the brain can process the stimulus and regain emotional composure.
3. Be Mindful of Sugar Intake for Dental Health
Eating too many jellybeans like Reagan did can harm health through tooth decay or excessive sugar intake. It is recommended to use sugar-free gum, sugar-free gummies, or nuts (almonds, walnuts) as alternatives to safely enjoy only the relaxation effect of chewing.
📌 Frequently Asked Questions (FAQ)
How long do I need to chew for mastication to effectively reduce stress? ▼
Neurophysiological research shows that cortisol levels begin to decrease and brainwaves start shifting to relaxing alpha waves about 2 to 3 minutes after chewing begins. Therefore, maintaining calm focus on chewing for at least 2 to 3 minutes is key to seeing benefits.
Is there a scientific mechanism behind mastication helping to suppress smoking urges or binge eating? ▼
Yes. When experiencing strong cravings (cigarettes, food), the brain craves a rapid surge of dopamine. Providing an oral chewing alternative allows the brain to partially satisfy its reward desire (via bypass dopamine release), helping control sharp impulse spikes. Behavioral science calls this 'alternative behavior formation'.
