Frequently asked questions
How much water should I drink in Indian summer?
Add 500ml-1L to your base requirement during Indian summers (March-June). If exercising, add another 500ml-1L per hour of activity.
Is 8 glasses of water per day accurate?
The "8 glasses" rule is a simplified guideline. ICMR recommends 35ml/kg body weight as baseline. A 70kg person needs ~2.4L/day from all sources.
