May 31, 2026 · 8m

Summary

Dave Asprey argues that brain fog often stems from poor circulation and sensory deprivation caused by modern footwear, not just mental fatigue. He explains how weak calf muscles and cushioned shoes restrict blood flow to the brain and disrupt nervous system balance. By walking barefoot and strengthening feet, listeners can restore oxygen supply and sensory feedback, significantly improving cognitive clarity and focus.
