Proper hydration is essential for health. This calculator estimates your daily water needs based on weight, physical activity, and environmental factors.
Using the Daily Water Intake Calculator is straightforward:
General recommendation: 1.5-2 liters (8 cups) for adults. Actual needs vary by weight, activity, and climate. This calculator provides personalized recommendations.
Base intake = weight(kg) x 30-35ml. Add 300-500ml per 30 min of exercise, 15-20% more in hot/humid climates, and 700-900ml for breastfeeding.
Yes. Food provides about 600-800ml of water daily. So actual drinking need = total need - food water. This calculator accounts for that.
Yes, excessive water in a short time can cause hyponatremia (water intoxication). Symptoms include headache, nausea, confusion. Drink 150-250ml at a time.
Easiest method: check urine color. Pale yellow = hydrated, dark yellow = need water, colorless = may be overhydrated. Normal adults urinate 4-7 times daily.
