The Science Behind Cognitive Health and Nightly Habits
We’ve all seen the viral ads: a picture of a senior chewing a mysterious green leaf with the promise that their memory will “come back strong” in just days. But is there any truth to the idea that what we do—or chew—before bed can impact our brain?
While there is no “magic leaf,” modern neuroscience suggests that the relationship between our mouth, our stomach, and our sleep is vital for keeping our minds sharp.
1. The Surprising Link Between Chewing and the Brain
Believe it or not, the act of chewing (mastication) is actually linked to brain health. Research published in the Journal of American Geriatrics Society suggests that the physical act of chewing increases blood flow to the hippocampus—the part of the brain responsible for memory and learning.
- The Reality: Simply chewing a leaf once won’t fix dementia. However, maintaining good oral health and the ability to chew effectively helps keep the brain’s “memory center” stimulated.
