Fuelin Sessions Heat Acclimation, Hydration, and Hormones: A Female Physiology Deep Dive with Dr. Lindsey Hunt
Sep 25, 2025
Dr. Lindsey Hunt, a senior sports scientist with expertise in environmental physiology at Precision Fuel and Hydration, delves into heat acclimation tailored for athletes, especially women. She distinguishes between acclimatization and acclimation, outlines ideal protocols, and emphasizes safety in heat training. Key insights include how menstrual cycles can influence training intensity and hydration needs. Additionally, she discusses effective methods like sauna use and hot water immersion for achieving heat adaptation, advocating for individualized strategies in preparation.

Episode notes
Prioritize Active Heat Acclimation
- Do active heat acclimation when possible: ~60 minutes per day for ~10 sessions to get robust adaptations.
- Train at low-to-moderate intensity and progressively overload within those heat sessions.
Start With Expert-Supervised Sessions
- Use a facility or expert initially for safety and to learn proper heat-session pacing and monitoring.
- Then apply those lessons to at-home heat training if needed.
Use HR, RPE And Power To Guide Intensity
- Target ~75–80% HRmax in ~38–40°C with moderate humidity, adjusting intensity by environment.
- Use RPE, power and heart-rate responses to guide real-time intensity adjustments.
