How Water Intake Is Calculated
The base formula uses 35ml per kg of body weight โ the WHO standard. This is then multiplied by activity factor (1.0 to 1.6) and climate factor (1.0 to 1.3 for Indian summers). Pregnancy adds 300ml/day and breastfeeding adds 700ml/day per medical guidelines.
Frequently Asked Questions
How much water should I drink per day in India?
For an average Indian adult (70kg, moderately active, hot climate): approximately 3.0โ3.5 litres per day. During summer, this increases to 3.5โ4L. The exact amount depends on weight, activity, and weather.
Does the 8 glasses rule apply for Indians?
The "8 glasses = 2L" rule is for temperate climates. For India โ especially Gujarat, Rajasthan, Maharashtra summers โ you need 10โ14 glasses (2.5โ3.5L) due to heat and sweating. This calculator uses India-specific climate factors.
How much extra water during workout?
Drink 500ml to 750ml extra per hour of moderate exercise. For intense workouts, add 750ml to 1000ml per hour. This calculator automatically adds workout water based on your session duration.
How much water should pregnant women drink?
Pregnant women need approximately 300ml more than their base requirement. Breastfeeding mothers need an additional 700ml per day. Both are included in this calculator's adjustments.
What are signs of dehydration?
Dark yellow urine, dry mouth, headache, fatigue, dizziness, and reduced urine frequency are common signs. In Indian summers, dehydration can occur quickly โ check urine colour regularly. Pale yellow = well hydrated.
Does tea or coffee count as water intake?
Partially. Unsweetened tea and coffee contribute about 80% of their volume toward hydration. Sodas and alcohol do not count โ they increase dehydration. Plain water, coconut water, and buttermilk (chaas) are best.
