Why do teens need salt?

Teens need salt, primarily for its sodium content, which is essential for maintaining proper fluid balance, nerve function, and muscle contractions. During adolescence, their bodies are growing rapidly, and sodium plays a crucial role in supporting these physiological processes. Additionally, active teens may lose sodium through sweat during physical activities, making it important to replenish it for overall health and performance. However, it's essential to consume salt in moderation, as excessive intake can lead to health issues.
