How Much Water Should You Drink Daily?
This estimates daily water needs based on weight, activity, and climate — more personalized than the generic "8 glasses" rule.
The Base Calculation
About 30-35 ml per kg of body weight, adjusted upward for activity and hot/humid climates.
Signs You Need More Water
Thirst, dark urine, fatigue, and headaches can signal dehydration. Exercise and illness increase needs.
Frequently Asked Questions
Is 8 glasses/day accurate?
It's a reasonable general guideline, but individual needs vary based on size, activity, and climate.
Can you drink too much water?
Yes, though uncommon; very large amounts quickly can be dangerous (hyponatremia).
Does caffeine dehydrate you?
It has a mild diuretic effect but moderate consumption still contributes to fluid intake.
