Factors Affecting Your Water Needs

Not everyone needs the same amount of water. Your ideal intake depends on several factors:

Larger individuals typically need more water than smaller ones. A common recommendation is to drink 0.5-1 ounce of water per pound of body weight.

The more you move, the more you need to drink. Intense exercise can significantly increase your hydration needs.

3. Climate

Hot or humid weather causes increased sweating and water loss. Living at high altitudes can also increase water requirements.

4. Health Status

Certain medical conditions and medications may increase your water needs. Fever, vomiting, or diarrhea can cause rapid dehydration.

5. Pregnancy or Breastfeeding

Women who are pregnant or breastfeeding need additional fluids to stay hydrated.

Signs You May Need More Water

• Dry mouth or lips
• Fatigue or dizziness
• Headaches
• Infrequent urination
• Strong-smelling urine
