Neuroscientist Warns: Sitting Is Shrinking Your Brain (And Exercise Doesn’t Cancel It)

Описание: Are your innocent daily habits silently shrinking your brain? As a neuroscientist, I'm exposing 5 common behaviors—from "doomscrolling" to chronic sitting—that lead to measurable brain atrophy and cognitive decline. 👇 Watch this before your next scroll.

🧠 In This Video: We often think of memory loss and brain fog as inevitable parts of aging. But groundbreaking research in 2026 reveals that everyday habits are physically thinning our gray matter and blocking neurogenesis (the growth of new brain cells).

In this episode of House Call, Dr. Dan Monti breaks down the neuroscience behind "Digital Dementia," the toxic impact of Ultra-Processed Foods (UPFs), and why "hustle culture" is flooding your brain with cortisol. You will learn how to protect your hippocampus, boost BDNF levels, and activate your glymphatic system for a healthier, sharper mind.

We dive deep into the latest medical studies from Vanderbilt, UCSF, and the Mayo Clinic to show you exactly how these habits affect your neurology—and more importantly, how to reverse the damage.

🔍 Key Neuroscience Topics Covered:

🟡 The "Digital Dementia" Epidemic: How social media fragmentation and doomscrolling thin the prefrontal cortex, leading to symptoms similar to cognitive decline.

🟡 Sedentary Aging: Why sitting for long periods (even if you exercise!) reduces blood flow to the medial temporal lobes and lowers BDNF.

🟡 The Cortisol Trap: How chronic stress and high cortisol levels shrink the brain's memory center.

🟡 The Gut-Brain Axis: The link between convenience foods, systemic inflammation & neurodegeneration.

🟡 Sleep & Detox: Understanding the brain's nightly "rinse cycle" via the Glymphatic System.
