Your brain-nerves run on electricity. That’s how we think.
They are insulated with a fatty substance called myelin. That prevents “short circuits.”
Aging eats up the insulation. This causes Dementia or MS.
A fun activity stops this “short circuit” process — a new study published by the National Academy of Sciences proves it.
The researchers behind this new study wanted to see whether there was a relationship between cardiovascular fitness (how well your body uses oxygen during exercise) and the health of the brain’s white matter, which includes myelin.
They studied 125 adults, ranging from 22 to 94 years old, measuring their VO2 max—an indicator of cardiovascular fitness—and using a special MRI technique to assess myelin levels in the brain.
Here are the key findings:
-
1. Higher fitness levels were linked to better myelination, especially in parts of the brain most prone to early degeneration, like the frontal lobes and other major white matter fiber tracts.
2. This link was strongest in middle-aged and older adults, suggesting that staying fit as you age could be especially important for your brain health.
3. In participants with lower VO2 max scores, myelin levels declined more rapidly with age, while those with higher fitness levels experienced less decline.
The researchers didn’t just find that higher fitness correlates with better brain health in a straight line; they also found that this relationship gets stronger as we age. In other words, the more fit you are, the more likely you are to protect your brain from degeneration as you grow older.
Something interesting: I’ve helped more than a thousand clients to stop or reverse Alzheimer’s and other types of dementia.
My approach kinda bypasses this study. Instead of improving cardio fitness to deliver more oxygen, my method directly increases oxygen levels in the brain. To stop dementia, we use simple techniques you can learn here…
You can also reverse MS. The MS approach is a little different, though. It focuses on diet and lifestyle changes (explained in detail here)…
