Why Proper Hydration Matters
Water is essential for nearly every bodily function. Adequate hydration helps maintain healthy skin, supports kidney function, regulates body temperature, aids digestion, and can even improve cognitive performance. Even mild dehydration can cause headaches, fatigue, and difficulty concentrating.
Signs of Dehydration to Watch For:

Frequently Asked Questions About Water Intake
Does coffee and tea count toward my daily water intake?
While caffeine has mild diuretic properties, moderate consumption of coffee and tea still contributes to your overall fluid intake. However, water should remain your primary hydration source.
Can you drink too much water?
Yes, though rare, overhydration (hyponatremia) can occur when you drink excessive amounts of water in a short time, diluting sodium levels in your blood. This is most common among endurance athletes.
Do I need to drink more water when exercising?
Absolutely. The American Council on Exercise recommends drinking 17-20 ounces of water 2-3 hours before exercise, 8 ounces during warm-up, 7-10 ounces every 10-20 minutes during exercise, and 8 ounces within 30 minutes after exercise.
How does altitude affect hydration needs?
At higher altitudes, your body loses more water through respiration as you breathe faster and deeper. If you're at high elevation, increase your water intake by 1-2 cups per day.
