How much water should I actually drink in a day?

Roughly 30 ml per kilogram of body weight is a reasonable starting point — about 2.1 litres for a 70 kg adult — and more in a North Indian summer or if you are physically active. Thirst is a decent guide for most healthy people. Pale straw-coloured urine is a better one than any fixed number.

The familiar eight-glasses rule has no strong origin and no strong evidence. It is not harmful, it is just arbitrary, and it ignores body size, climate and activity — three things that vary enormously.

What changes the number

  • A Panchkula summer can double sweat losses compared with December
  • Exercise, particularly anything that leaves you visibly sweating
  • Tea and coffee do count towards intake, despite the common claim otherwise — the diuretic effect is modest
  • High-protein diets and some medications increase requirement

When more is not better

Drinking far beyond thirst is not virtuous and, in rare cases, is dangerous. If you have kidney disease, heart failure, or are on diuretics, your fluid intake is a medical question with a specific answer, and your physician should give it.
