Find exactly how much water your body needs daily based on your weight, activity, and India's climate.
Each 💧 = one 250ml glass
This includes all fluid intake (water, dal, chaas, juice, etc.). About 20% of daily water comes from food. Adjust based on urine colour — pale yellow is ideal.
India's climate — particularly the long summer season, high humidity in coastal cities, and extreme temperatures in the Indo-Gangetic plains — makes dehydration a serious daily concern. At 35°C with 70% humidity, your body can lose up to 1–1.5 litres of water per hour through sweat during physical activity.
Chronic mild dehydration (losing just 1–2% of body water) reduces cognitive performance, causes fatigue, headaches, and poor concentration — symptoms many Indians attribute to "heat" rather than dehydration. Most adults need significantly more than the commonly cited "8 glasses a day," especially during Indian summers.
Visibility drives behaviour. A 1-litre bottle on your desk means you'll drink 40% more than if water is in another room. Refill it twice and you're done.
Your body loses 400–500 ml overnight through breathing. Drinking 2 glasses first thing rehydrates you and kickstarts digestion — a habit recommended in Ayurveda and modern nutrition alike.
Plain water during intense heat can dilute sodium. A glass of nimbu pani with a pinch of black salt replaces both water and electrolytes — far better than packaged sports drinks.
Cucumber, tomatoes, watermelon, dahi, chaas, dal, and sabzi all contribute to hydration. Eating a balanced Indian thali provides 400–600 ml of water equivalent.
A phone alarm every hour from 8 AM to 8 PM — just 12 alarms — if each triggers one sip-to-glass, hits your daily target almost automatically.
Pale straw yellow = well hydrated. Dark yellow or amber = dehydrated. Colourless = overhydrated. The urine colour test is the simplest, most accurate real-time hydration check.
