After activity, which hydration guideline is correct?

After activity, which hydration guideline is correct?

• A. 24 ounces for every pound lost
• B. 24 ounces per hour
• C. 24 ounces total only
• D. 48 ounces for every two pounds lost

Answer: (A)

Matching fluid intake to sweat loss after activity is the key idea. The guideline of about 24 ounces of fluid for every pound you lost during exercise directly ties hydration to how much you sweated, helping you return to your pre-exercise weight and restore your body's fluid balance within a few hours. This approach is practical because sweat rates vary with intensity, duration, and individual differences, so replacing what you actually lost is more effective than a fixed amount. If you simply drink a fixed amount, you might under-hydrate after a tough session or risk overhydration after a shorter one. The option that suggests 24 ounces per hour doesn’t account for how much you actually sweated, which can lead to under- or over-hydration. Saying only 24 ounces in total is typically not enough after substantial sweating. The alternative phrasing of 48 ounces for every two pounds lost is the same as 24 ounces per pound, but the standard, straightforward guidance coaches emphasize is the per-pound rule, making that one the clearest and most reliable choice.
