Which of the following practices is recommended to prevent heat stress during exercise?

Staying well-hydrated is a crucial practice for preventing heat stress during exercise. When engaging in physical activity, especially in hot and humid conditions, the body loses fluids through sweat. Adequate hydration helps regulate body temperature, maintain blood volume, and support overall cardiovascular function.

When you are properly hydrated, your body can effectively cool itself through perspiration, which is essential for thermoregulation. This cooling mechanism can help prevent the negative effects of heat stress, such as heat exhaustion or heat stroke, which can occur when the body is unable to dissipate heat effectively due to dehydration.

Maintaining hydration before, during, and after exercise is important for sustaining performance and protecting health, especially in conditions that may lead to increased sweating and fluid loss. Therefore, prioritizing hydration is one of the best protective measures against heat-related illnesses during physical activity.
