Water Intake Calculator
Calculate your daily water intake needs based on your weight, activity level, and climate. Stay hydrated for optimal health and performance.
Why is Hydration Important?
Proper hydration is essential for every bodily function, from temperature regulation to nutrient transport. Water makes up about 60% of your body weight and is crucial for maintaining health and performance.
Daily Water Needs: Your water intake should be based on your body weight, activity level, climate conditions, and overall health status. The general recommendation is 30-35ml per kg of body weight.
Hydration Benefits:
- • Regulates body temperature
- • Transports nutrients and oxygen
- • Lubricates joints and tissues
- • Aids digestion and metabolism
- • Improves cognitive function
- • Enhances physical performance
Factors Affecting Water Needs:
- Body Weight: More weight = more water needed
- Activity Level: Exercise increases water loss
- Climate: Hot weather increases needs
- Diet: High protein/salt increases needs
- Health Status: Illness may increase needs

Frequently Asked Questions About Hydration
Why is proper hydration important?
Proper hydration is essential for every bodily function, from temperature regulation to nutrient transport. Water makes up about 60% of your body weight and is crucial for maintaining health and performance. Even mild dehydration can affect cognitive function, physical performance, and overall well-being.
How much water should I drink per day?
Your daily water needs depend on your body weight, activity level, climate, and overall health. The general recommendation is 30-35ml per kg of body weight. For example, a 70kg person needs about 2.1-2.5 liters daily. Active individuals and those in hot climates need more to replace lost fluids through sweat.
How do I know if I'm drinking enough water?
Monitor your urine color - pale yellow indicates good hydration, while dark yellow suggests you need more water. Other signs of adequate hydration include clear skin, good energy levels, and regular bathroom visits. Thirst is actually a late sign of dehydration, so don't wait until you're thirsty to drink water.
Should I drink water during exercise?
Yes, drink water before, during, and after exercise. For workouts under 60 minutes, water is usually sufficient. For longer or more intense sessions, consider electrolyte replacement drinks. Drink 500ml 2-3 hours before exercise, 250ml 15-20 minutes before, and continue drinking during your workout to replace lost fluids.
Can I drink too much water?
Yes, overhydration (water intoxication) is possible but rare. It occurs when you drink more water than your kidneys can process, diluting your blood sodium levels. This is most common during endurance events. For most people, drinking water throughout the day based on thirst and urine color is safe and effective.
What about other beverages like coffee and tea?
Coffee and tea do contribute to your daily fluid intake, but they also have diuretic effects. While they're not dehydrating as once thought, they shouldn't replace water entirely. Aim to get most of your fluids from water, and limit caffeine intake, especially in the evening.
How does climate affect my water needs?
Hot and humid climates increase water needs due to increased sweating and faster fluid loss. In hot weather, you may need 1-2 liters more water daily. High altitude also increases water needs due to increased respiration and potential altitude sickness. Always adjust your intake based on your environment.
