In detail: Water Intake Calculator for 50kg
A 50kg body needs roughly 1.75 litres of fluid intake per day — but "fluid intake" includes everything: tea, coffee, soft drinks, and the ~20% of your intake that typically comes from food. Plain water is a subset, not the whole target.
At this bodyweight, over-hydration is a real thing — drinking much more than 1.75L/day of plain water doesn't produce additional benefit and can stress your kidneys if consistent.
Context matters: hot weather, exercise, breastfeeding, or illness can raise the target by 20–50%. The simplest check is urine colour — pale straw is ideal, darker than that suggests you're behind.
