A common misconception about hydration is that one should drink large amounts of water beyond the body's needs, regardless of activity or climate conditions. In fact, hydration requirements vary based on factors like activity level, climate, and individual physiology. The overall guideline is to drink when thirsty and ensure adequate fluid intake during intense exercise or hot weather rather than overhydrating in typical situations. Drinking fluids that contain electrolytes can be particularly beneficial during prolonged physical activities. It’s important to listen to your body’s cues for hydration.
