Episode notes
Key Environmental Factors for Heat Stress
- Temperature, humidity, solar radiation, and wind speed largely determine heat stress on athletes.
- Sweat evaporation is critical; if sweat doesn't evaporate, the body just dehydrates without cooling effectively.
Wear Moisture-Wicking Clothes
- Choose clothing that wicks sweat to aid evaporation but avoid saturation of the fabric.
- Saturated clothing impairs sweat evaporation, reducing cooling effectiveness.
Hydration's Impact on Heat Regulation
- Hydration is crucial as dehydration impairs sweat and skin blood flow, reducing heat loss.
- Dehydration increases heart rate and hampers cardiovascular function during exercise.
