Conversations, Not Crosswords: The Brain’s Top Health Hack
Neurologist Dr. Douglas Scharre says the brain benefits most from social interaction—talking, reading, and quick mental processing—because it strengthens neural connections and builds cognitive reserve that helps guard against dementia; while activities like puzzles help, passive TV/phone time can be harmful. He advises a holistic brain-health plan: quality sleep, metabolic health (blood pressure, diabetes, cholesterol) management, stress reduction, a Mediterranean-style diet, and a balanced mix of aerobic, strength, flexibility, and balance exercises, with regular tracking of diet, sleep, and activity to catch issues early.
