What should be considered to prevent heat injuries?

Hydration is crucial in preventing heat injuries during physical activity, especially in warm or humid environments. When exercising, the body loses fluids through sweating, which is essential for regulating body temperature. Failure to replenish these lost fluids can lead to dehydration, heat exhaustion, or even heat stroke. Drinking water before, during, and after exercise helps maintain optimal hydration levels, ensuring that the body's thermoregulation and performance are not compromised.

While warming up indoors can be beneficial in certain contexts, it does not directly address the risks of heat injuries that can occur during subsequent outdoor activities. Wearing heavy clothing can actually increase the risk of overheating, as it prevents heat dissipation. Similarly, exercising in hot environments without proper hydration can exacerbate the likelihood of heat injuries. Therefore, thorough hydration stands out as the most effective preventive measure against heat-related issues.
