Tips for Staying Hydrated
  • Carry a reusable water bottle with you throughout the day
  • Set reminders to drink water regularly
  • Drink a glass of water before each meal
  • Eat water-rich foods like fruits and vegetables
  • Flavor water with fruits or herbs if you find plain water boring
  • Monitor your urine color - pale yellow indicates good hydration
Note: While this calculator provides a good estimate, individual water needs can vary. Listen to your body's thirst signals and adjust your intake accordingly. Consult with a healthcare professional for personalized advice.
About Water Intake

Water is essential for nearly every bodily function, including:

  • Regulating body temperature
  • Lubricating joints
  • Delivering nutrients to cells
  • Flushing out waste and toxins
  • Supporting brain function
  • Maintaining blood pressure
Signs of Dehydration:
  • Thirst
  • Dark yellow urine
  • Fatigue
  • Headache
  • Dry mouth and lips
  • Dizziness
  • Reduced urination
Important: Severe dehydration can be life-threatening. Seek medical attention if you experience extreme thirst, confusion, rapid heartbeat, or no urination for 8+ hours.
Water Intake Factors
Weight

Larger bodies require more water. A common guideline is 30-35 ml per kg of body weight.

Activity Level

Exercise increases water loss through sweat. For every 30 minutes of moderate exercise, you may need an additional 250-500 ml of water.

Climate

Hot and humid environments cause increased sweating and water loss. You may need 500-1000 ml extra water in hot conditions.

Pregnancy & Breastfeeding

Pregnant women need additional water for the developing baby and increased blood volume. Breastfeeding mothers need extra water to produce milk.

Caffeine & Alcohol

Both have diuretic effects, increasing urination and potentially leading to dehydration if not balanced with additional water intake.

Health Conditions

Certain conditions like fever, vomiting, diarrhea, or kidney stones may increase water needs. Consult a healthcare provider for specific recommendations.
