Water—so essential yet often overlooked. We’ve all heard the common advice: “Drink 2 liters a day,” but is that really enough? Or maybe too much?
Unfortunately, hydration is often underestimated, and dehydration affects our bodies more than we realize. Fatigue, headaches, poor concentration, and even increased appetite—these can all be signs that you’re not drinking enough water.
So, what are the actual scientific recommendations for water intake? How should you adjust your hydration based on age, physical activity, and lifestyle? Let’s find out!
How Much Water Should You Drink? Age and Activity-Based Guidelines
According to the European Food Safety Authority (EFSA) and the Institute of Medicine (IOM), daily water intake recommendations vary depending on age, gender, and physical activity:
📌 Children (4-8 years old) – 1.6 L per day
📌 Children (9-13 years old) – 1.9-2.1 L per day
📌 Teenage girls (14-18 years old) – 2 L per day
📌 Teenage boys (14-18 years old) – 2.5 L per day
📌 Adult women – 2-2.7 L per day
📌 Adult men – 2.5-3.7 L per day
📌 Pregnant women – at least 2.3 L per day
📌 Breastfeeding women – at least 2.7-3 L per day
👉 But that’s not all! If you exercise regularly, do physical labor, or live in a hot climate, your water needs increase by 500-1000 ml per hour of activity!
📌 Example: Someone working out for an hour at the gym should drink an additional 0.5-1 L of water to compensate for fluid loss.
Why Is Hydration So Important? Science-Backed Facts
💧 Water is life—literally! Our bodies are composed of 50-70% water, and even a slight deficiency negatively impacts our health.

So… do you still think drinking enough water is unimportant? 😲
Why Do So Many People Ignore Hydration?
Despite the overwhelming evidence, many people still don’t drink enough water. Why?
❌ We don’t feel thirsty—but we should drink regularly!
Thirst is already a sign of dehydration. You should drink water before feeling thirsty.
❌ Confusing thirst with hunger
Many people reach for a snack instead of a glass of water. Dehydration can often mimic hunger.
❌ Drinking coffee instead of water
Coffee and tea have a diuretic effect, meaning they don’t hydrate as effectively as pure water.
❌ Lack of habit
Many people simply aren’t used to drinking water consistently. Without a habit, it’s easy to forget.

1️⃣ Start your day with a glass of water – Morning hydration wakes up your body.
2️⃣ Always keep water nearby – Place a bottle on your desk, in your car, or in your bag.
3️⃣ Set reminders – Use an app to track your daily water intake.
4️⃣ Add flavor! – If plain water is boring, infuse it with lemon, mint, cucumber, or fruit.
