FAQ
Q: How much water should I drink?
A: A common guideline is to drink half your body weight in ounces. Active individuals need more to replace fluids lost through sweat.
Q: Does exercise affect water needs?
A: Yes. More exercise means more sweat and greater fluid loss. Adjust your intake accordingly on workout days.
Q: Can I drink too much water?
A: While rare, overhydration (hyponatremia) can be dangerous. Listen to your body and drink when thirsty.
