#595 The Fasting Mind: How Silence Heals the Brain
Jul 10, 2026 · 12m
Summary
Dr. Robert Puff argues that constant mental input exhausts the brain, preventing emotional resilience, drawing a parallel between physical intermittent fasting and "mental fasting" to clear emotional waste. He explains how silence allows the mind to process stress, citing Carl Jung’s retreats and Blaise Pascal’s insights on solitude. Practical tips include a screen-free morning, silent commutes, and phone-free walks to restore mental clarity.
