What proactive measure should lifeguards encourage to prevent heat-related illnesses?

Reminding swimmers to drink plenty of water is a vital proactive measure lifeguards can encourage to prevent heat-related illnesses. Adequate hydration helps regulate body temperature and replaces fluids lost through sweat. When individuals become dehydrated, they are at a higher risk of heat exhaustion and heat stroke, especially during hot weather or prolonged activity in the sun. By emphasizing the importance of drinking water, lifeguards promote the health and safety of swimmers, ensuring they remain hydrated and can enjoy their time in the water without the risk of heat-related issues.

While other measures like taking breaks, avoiding peak sun hours, and establishing shaded areas also contribute to preventing heat-related illnesses, hydration is an immediate and crucial component of maintaining health and comfort for all participants at the pool.
