Understanding Your Hydration Needs
The "8 glasses a day" rule is a myth. Your actual water needs depend on various factors including age, weight, activity level, and climate.
How to Calculate Your Daily Water Intake
A general formula: Drink 30-35ml of water per kg of body weight. For a 70kg person, that's approximately 2.1-2.5 liters daily.
Factors Affecting Water Needs
- Exercise: Add 400-800ml for every hour of physical activity
- Climate: Hot and humid weather increases water loss
- Health Conditions: Fever, diarrhea, or vomiting require extra fluids
- Pregnancy & Breastfeeding: Increased needs for mothers
Signs You're Drinking Enough Water
Your urine should be pale yellow. Dark urine indicates dehydration.
Best Hydration Practices
- Start your day with 2 glasses of water
- Drink water before you feel thirsty
- Keep a water bottle handy
- Drink more during exercise
- Include water-rich foods in your diet
