Daily water needs vary substantially among people and circumstances.

The Claim

Every person should drink 2 liters of water per day.

Verified by Lenz ·

The Short Version

A fixed two-liter drinking target does not apply to everyone. Authoritative recommendations vary by sex, age, activity, climate, health, and other circumstances, and many intake figures include water obtained from food and all beverages. Two liters may be suitable for some adults, but the evidence does not support it as a universal daily requirement.

Caveats

  • Guideline figures often refer to total water from food and beverages, not plain water alone.
  • Water needs change with age, sex, activity, climate, pregnancy, illness, and diet.
  • Two liters may suit some adults but should not be treated as an exact universal requirement.
