What is Daily Water Intake?

Daily Water Intake refers to the total amount of fluid your body needs each day to stay properly hydrated. Water is essential for every function in your body — from regulating temperature to transporting nutrients and removing waste.

  • ✓ Supports digestion, absorption and nutrient transport
  • ✓ Maintains body temperature and joint lubrication
  • ✓ Helps with weight management and appetite control
  • ✓ Crucial for energy, focus and overall health

Daily Water Limits by Age

There is no strict "upper limit" for water intake for healthy people, but drinking too much too quickly can cause water intoxication (hyponatremia). Safe daily amounts vary by age, activity, climate, and health. Below are general guidelines from health authorities (IOM, EFSA, WHO).

  • ✓ Infants (0–6 months): 0.7–1 L/day (mostly from milk)
  • ✓ Children (4–8 years): 1.2–1.7 L/day
  • ✓ Teens (9–13 years): 1.6–2.4 L/day
  • ✓ Adults (14+ years): 2–3.7 L/day (men usually higher)
  • ✓ Safe upper limit: ~0.8–1 L per hour max, never force excess

Common Questions

Water intake questions come up a lot. Here are the most common ones answered clearly — so you can hydrate smartly with your Horizons calculator.

How much water should I really drink per day?

General rule: **30–40 ml per kg** of body weight. For a 70 kg person that's 2.1–2.8 liters. Add more if active, hot weather, or pregnant/breastfeeding.

Is it bad to drink too much water?

Yes — overhydration (hyponatremia) can happen if you force >1 L per hour or drink far beyond thirst. Healthy kidneys handle 0.8–1 L/hour max safely.

Does coffee/tea count toward my water goal?

Yes — most caffeinated drinks contribute to hydration (in moderation). They’re not dehydrating unless you drink extreme amounts.

How do I know if I’m drinking enough?

Best signs: pale yellow urine, no thirst, good energy. Dark urine or dry mouth = drink more. Thirst is a late signal — don’t wait for it.

Should kids or elderly drink the same amount?

No — kids need less (1.2–2.4 L depending on age), elderly often need reminders (reduced thirst sensation). Activity/climate still adds extra.
