Consejos y buenas prácticas
- The 30 mL/kg baseline is widely cited — for a 70 kg adult that's ~2.1 L/day before activity/climate adjustments.
- Food contributes ~20% of typical water intake; the calculator focuses on drinking water.
- Pregnancy, breastfeeding, and certain medications change requirements significantly — consult a clinician for those.
- Caffeine and alcohol both have diuretic effects; the rule-of-thumb is to drink an equal volume of water alongside.
- Thirst is a lagging indicator — by the time you're thirsty you're already mildly dehydrated. Sip throughout the day.
