Episode notes
Heat Raises Heart Rate and Strain
- Exercising in heat raises heart rate and perceived exertion due to heat stress and cardiovascular strain.
- Heat reduces the body's maximum oxygen uptake (VO2 max), impairing performance endurance.
Hydrate Smart for Heat
- Stay well hydrated before and during exercise to maintain vasodilation and sweating.
- Consider hyperhydration with sodium or glycerol to retain fluids and reduce heat strain.
Use Heat Acclimation for Adaptation
- Use heat acclimation over 10-14 days to adapt by lowering resting core temperature and increasing sweating.
- This reduces cardiovascular strain and improves performance and comfort in hot conditions.
