In this episode, Dina and Bob dig into sweat rate — what it is, how to measure it, and why it matters more than most athletes realize. Bob shares data from a recent sweat rate test during a long run (and felt the consequences). From there, the conversation branches into sex differences in sweat rate, hormone-related shifts across the menstrual cycle, and how testosterone and aging can change the hydration equation.

Topics include:

• What is sweat rate?
• The wide range of how much athletes sweat 
• How to calculate your sweat rate with a simple at-home test
• Hormones, aging, and heat adaptation—why your hydration needs might shift over time
• The cognitive and physical impacts of dehydration
• Why understanding your data is the key to better performance
