What is a recommended practice to prevent heat-related emergencies among swimmers?

Monitoring water intake during practice is essential in preventing heat-related emergencies among swimmers. When athletes engage in physical activity, especially in warm conditions, they lose fluids through sweat. If these fluids are not replenished, it can lead to dehydration, which significantly increases the risk of heat-related illnesses, such as heat exhaustion and heat stroke.

By ensuring that swimmers have regular opportunities to hydrate, coaches can help maintain optimal hydration levels, which supports overall performance and safety. It's important for athletes to drink water before, during, and after their workout sessions to effectively replace lost fluids. This practice fosters a safe training environment and minimizes the risks associated with exercising in high temperatures.

In contrast, encouraging athletes to practice in the hottest part of the day, limiting water breaks, and having them wear heavy clothing can all exacerbate the risk of heat-related issues, as these actions would hinder the athletes' ability to cool down and maintain hydration.
