Frequently Asked Questions
Why does my water intake depend on weight?
Your body size affects how much water you need. Larger bodies typically require more fluids to stay hydrated.
Do I need more water when exercising or in hot weather?
Yes. Physical activity and high temperatures increase fluid loss through sweat, so your water needs go up accordingly.
Can I drink too much water?
Yes, excessive water intake can lead to a rare condition called hyponatremia, where sodium levels in the blood become dangerously low.
Does food contribute to daily hydration?
Yes, many foods—especially fruits and vegetables—contain water and can contribute to your overall hydration needs.
