Brain Fog Starts in Your Feet (Scientifically Proven) : 1476

Dave Asprey shares his 15-year struggle with severe brain fog and how he discovered the root cause wasn't in his brain but in his feet. He explains the science linking weak calf muscles, reduced blood flow to the brain, and modern cushioned shoes that block essential sensory signals from the feet. This sensory deprivation keeps the nervous system in a survival state that tanks executive function. He outlines the barefoot walking and foot-strengthening protocols that lifted his fog and restored his mental clarity.
