Which of the following could have helped prevent Chris's symptoms of dizziness and lightheadedness?

Having water available at practice is essential for preventing symptoms like dizziness and lightheadedness, which can be signs of dehydration or overheating. Adequate hydration helps maintain fluid balance in the body, ensuring that blood volume and pressure are sufficient to support normal physiological functions. When athletes do not drink enough water, they risk dehydration, leading to decreased cardiovascular performance, increased heart rate, and potential heat-related illnesses, all of which can contribute to feelings of dizziness.

By ensuring that water is readily available during practice, athletes can hydrate as needed, reducing the risk of dehydration-induced symptoms. This is particularly important in environments where sweating may lead to significant fluid loss, which can happen in various climates and during prolonged physical activity. Access to water not only supports overall performance but also helps maintain homeostasis by enabling the body to regulate temperature and maintain adequate blood circulation.
