Frequently Asked Questions
How much water should I drink daily?
A common guideline is half your body weight in ounces (e.g., 150 lbs = 75 oz). However, this varies based on activity level, climate, and individual factors. Use this calculator for a personalized recommendation.
Does coffee count toward hydration?
Coffee and tea do contribute to hydration, but caffeine is a mild diuretic. For every cup of coffee, you may need an extra 4-6 oz of water. This calculator accounts for caffeine intake.
What are signs of dehydration?
Early signs include thirst, dark urine, fatigue, and headache. More severe symptoms include dizziness, confusion, and rapid heartbeat. If your urine is pale yellow, you're well hydrated.
How does exercise affect water needs?
You lose water through sweat during exercise. Aim to drink 4-8oz every 15-20 minutes during workouts. Weigh yourself before and after exercise—drink 16-24oz for every pound lost.
