Water is essential for body functions: regulating temperature, transporting nutrients, supporting the kidneys, and hydrating the skin. But the right amount is not a single number for everyone.

1. Why is water important?
Water makes up a large percentage of body weight and is involved in most vital functions. Even mild dehydration can cause headaches, fatigue, difficulty concentrating, or decreased physical performance. Good hydration also helps prevent kidney stones and constipation, but it is not a cure for everything.
2. How much water do you need?
General recommendations vary between organizations and individuals. Many adults need about 1.5 to 2 liters of fluids daily, but this includes water found in food and other beverages, not just plain water. You may need more or less depending on your weight, activity, weather, and health status.
Instead of chasing an ideal number, watch the color of your urine: light yellow to clear is often a sign of good hydration, while dark yellow may indicate a need for more. Thirst is also a useful indicator, but it diminishes with age or being busy.
3. Factors that increase your need for water
- Heat and humidity: Sweating increases fluid loss.
- Exercise: Especially long or intense workouts.
- Altitude: Dry air at high altitudes increases loss.
- Pregnancy and breastfeeding: Women need additional amounts as recommended by the doctor.
- Illness: Fever, vomiting, and diarrhea may cause rapid dehydration.
- Some medications: Diuretics and some other medications.
In these cases, you may need to increase fluids or replenish salts, but do not drink water excessively at once. Balance is important.
4. Signs of dehydration
- Severe thirst or dry mouth.
- Dark and low urine.
- Headache or dizziness.
- Unusual fatigue or difficulty concentrating.
- Dry skin or few tears (especially in children).
If the symptoms are severe, or appear in a child or elderly person, seek medical care. Severe dehydration is an emergency.
5. Build a drinking routine intelligently
Relying on 'I’ll drink when I remember' usually doesn’t work. Link drinking to existing habits:
- A glass of water after waking up.
- A glass with each meal.
- A glass before and after exercise.
- A glass at every break between tasks.
- Keep a visible water bottle on your desk.
If you forget, use a gentle reminder every hour or two, but do not drink a large amount at once. Spreading it throughout the day is better than 'catching up' in the evening.
6. Use water tracking in NexTab
The water tracking in NexTab helps you log the amount of water you drink during the day and see your progress toward your goal. Steps:
- Set a realistic goal, like 1.5 liters to start.
- Record every cup or bottle as you drink it.
- Check your progress mid-day, not just at the end.
- Adjust the goal according to the weather and your activity.
Don't let the goal be a source of stress. If you don't reach it, start fresh the next day, and try adding just one cup.
7. Common mistakes
- Drinking a large amount at once: can cause discomfort and doesn't make up for regular intake.
- Excessive water: rare but possible, and can be dangerous. Don't drink more than you need.
- Relying on sweetened drinks: may add calories and sugar. Water is the main choice.
- Ignoring thirst: especially during work or study.
- Do not change the goal: The requirement changes with the weather and activity.
Weekly Hydration Plan
- Day 1: Record what you usually drink without changing.
- Days 2–3: Add a cup after waking up and a cup with each meal.
- Days 4–5: Place a water bottle in a visible spot, and record every cup.
- Days 6–7: Review your progress, and adjust the goal according to how you feel.
Start by recording one cup
Open water tracking in NexTab, and set a simple goal for the day. Habits start with a small step.
Open water trackingFrequently Asked Questions
Is 8 cups a fixed rule?
It is not an exact rule for everyone. The requirement varies according to the body, activity, and weather. Use it as a starting point, and monitor your body's signs.
Do coffee and tea count as fluids?
Yes, but water remains the best option. Beverages containing caffeine may slightly increase urination in some people, but this does not mean all fluids are lost.
Can I drink all my requirement in the evening?
It is better to spread it throughout the day. Drinking a lot before bed may disturb your sleep.
Is water tracking suitable for children?
It can be used to encourage the habit, but children's needs vary. Consult a pediatrician if you have concerns.
