Did you know chronic stress can physically damage your brain?
Here’s the simple reason why:
➡️ Cortisol overstimulates hippocampus neurons
➡️ Overfiring neurons burn excessive energy
➡️ This creates oxidative stress inside brain cells
➡️ Over time, neurons degenerate and die
Neuron loss = neurodegeneration.
And neurodegeneration is what we see in dementia, Alzheimer’s, and Parkinson’s.
The goal isn’t eliminating cortisol—it’s preventing chronic overactivation that exhausts brain cells.
