This podcast interviews exercise physiologist Stacy Sims, PhD, about hydration for athletic performance. The discussion covers the science of hydration, debunking common myths like the 8-glass-a-day recommendation and the dehydrating effects of coffee. Sims emphasizes individualizing hydration strategies based on factors like sweat rate, exercise intensity, and menstrual cycle phase, suggesting using thirst, weight, urine color, and urine specific gravity to assess hydration. She advocates for adding small amounts of sodium and glucose to water, especially before and during intense exercise, to optimize fluid absorption. Listeners gain practical advice on improving hydration for better athletic performance and overall well-being.
