💧 Understanding Fluid Balance
Water Inputs
Fluids come from drinking water, other beverages (tea, coffee, juice), and water-rich foods (fruits, vegetables, soups).
Water Outputs
The body loses water through urine, sweat (especially during exercise), breathing, and digestion.
Why Balance Matters
Maintaining equilibrium is crucial for temperature regulation, joint lubrication, nutrient transport, and organ function.

Myth: Coffee Dehydrates You
• Fact: While caffeine is a mild diuretic, the fluid in coffee/tea still contributes to hydration.
• Moderate consumption doesn't cause dehydration.

Frequently Asked Questions
Q: How much water should I drink daily?
A: General recommendations are about 35ml per kg of body weight (0.5-1 ounce per pound). However, needs vary based on activity level, climate, health status, and individual factors. Our calculator provides personalized recommendations.
Q: Do I need more water when exercising?
A: Yes, you need additional water during exercise to replace fluids lost through sweat. Generally, add 12-16 oz (355-473ml) for every 30 minutes of moderate to intense exercise.
Q: Does coffee and tea count toward water intake?
A: Yes, all fluids contribute to hydration, including coffee, tea, and other beverages. However, water is the best choice as it's calorie-free and doesn't contain caffeine or added sugars.
Q: What are signs of proper hydration?
A: Signs of good hydration include pale yellow urine, regular urination, moist mouth and lips, good skin elasticity, and stable energy levels. Dark yellow urine often indicates dehydration.
Q: Can you drink too much water?
A: Yes, drinking excessive amounts of water can lead to water intoxication or hyponatremia (low sodium levels). Follow recommended amounts and listen to your body's thirst signals.
Q: Should I drink electrolytes?
A: For most people, a balanced diet provides enough electrolytes. However, during intense exercise lasting over an hour, or in very hot climates, electrolyte drinks can help replace salts lost through sweat.
