Measuring hydration levels can be accomplished through various methods, with urine color and frequency being practical indicators. Clear or light-colored urine generally signals proper hydration, while dark urine may indicate dehydration. Monitoring thirst levels is also crucial; feeling thirsty suggests the need for fluid intake. Additionally, weighing oneself before and after exercise can help determine fluid losses, guiding rehydration efforts. For athletes, using electrolyte-rich drinks for recovery can be beneficial. Staying vigilant about hydration supports optimal performance and overall health.
