A common sign of dehydration is increased thirst, often accompanied by dark yellow urine. Other symptoms may include dizziness, dry mouth, fatigue, and reduced urine output. In cases of severe dehydration, individuals may experience confusion or fainting. Regularly drinking fluids, especially in hot weather or during intense exercise, is crucial for maintaining hydration levels. Monitoring urine color can serve as a practical indicator of hydration status. Adequate hydration plays a vital role in maintaining physical performance, regulating body temperature, and supporting overall health.
