Hydration plays a crucial role in preventing cramps during exercise by maintaining proper fluid balance in the body. When dehydrated, the body struggles to regulate muscle function and can lead to conditions like cramps and spasms. Adequate hydration ensures that muscles receive the necessary nutrients and oxygen while facilitating the removal of waste products during physical activity. It is essential to drink fluids before, during, and after exercise to replace lost fluids and electrolytes. This practice can significantly reduce the risk of muscle cramps, enhancing overall performance and recovery.
