Headline: Is Your Back Pain Actually a Brain Problem? | The Brain-Body Connection
How is your back and your brain related?
It’s a question Dr. Jeff Cumro gets asked constantly, and the answer is more fascinating than you might think! In today’s video, we’re diving into the "neurology of the spine" to explain why movement is literally food for your brain.
In this video, you’ll learn:
• Why 90% of your brain's nutrition comes from spinal movement (The Roger Sperry Study).
• How your brain's balance centers dictate your posture (and why people hunch over grocery carts).
• The real reason "sitting is the new smoking" (it’s not just about calories!).
• A simple posture test to see how your spine controls your stress response.
