How much water should I drink per day?

The commonly cited 8 glasses (64oz) is a rough baseline. Your actual needs depend on body weight, activity level, climate, and caffeine intake. A common formula is half your body weight in ounces as a starting point, adjusted for activity and environment.

Does coffee count toward my daily water intake?

At moderate consumption (1–3 cups per day), coffee contributes to your fluid intake despite its mild diuretic effect. However, heavy caffeine consumption requires additional water to offset the net fluid loss.

How do I know if I'm drinking enough water?

The most reliable indicator is urine color — pale yellow means well hydrated, dark yellow means you need more water. Other signs of adequate hydration include rarely feeling thirsty and urinating regularly throughout the day.

Should I drink more water when working at a desk?

Desk workers often underdrink because sedentary work doesn't trigger thirst as readily as physical activity. Setting regular drinking reminders or using a tool like DeskSip can help maintain consistent intake during work hours.
