How Much Water Should You Drink a Day?

Staying hydrated is crucial for energy, digestion, skin health, and weight management. The amount of water your body needs daily depends on your age, weight, activity level, and climate.

A general guideline is to drink about 30–40 ml of water per kg of body weight. That’s roughly 8–12 cups for the average adult.

Weight (kg) Recommended Water (liters) Equivalent in Cups (approx.)
50 kg 1.5 – 2.0 L 6–8 cups
70 kg 2.1 – 2.8 L 8–11 cups
90 kg 2.7 – 3.6 L 11–14 cups

Note: Your actual water needs may vary based on factors such as exercise, hot weather, or medical conditions. Aim to drink consistently throughout the day, and remember that water-rich foods count too!
