Chapter 01 — Health & Wellness
How much water should I drink per day?
Roughly 2–3 liters total fluid for most adults, including what's in food and coffee. The old '8 glasses' rule is a guideline, not a prescription — thirst and pale-yellow urine are better signals.
Follow-up questions
Does coffee dehydrate you?
No. The diuretic effect is mild and the water in the cup more than compensates.
Can you drink too much water?
Yes — hyponatremia, when sodium drops dangerously, usually only in endurance athletes or compulsive drinkers.
Do I need electrolytes?
Only if you sweat heavily, have a stomach bug, or drink very large volumes quickly. Most people get enough from food.
Do coffee and tea count toward hydration?
Yes. The diuretic effect of normal caffeine intake is smaller than the fluid the drink provides.
