During hot weather workouts, proper hydration is essential to maintain performance and prevent heat-related illnesses. Increased temperatures cause enhanced sweating, leading to potential water and electrolyte loss, which can result in dehydration and decreased physical capacity. Staying adequately hydrated helps regulate body temperature, supports cardiovascular function, and maintains endurance. Individuals should aim to drink water before, during, and after exercise, ensuring they replenish lost fluids. Awareness of hydration needs in hot conditions is vital for optimal health and safety during physical activity.
