Hydration in Malta: How Much Water Do You Really Need?

"Drink eight glasses of water a day" is one of those pieces of health advice that everyone repeats but nobody can trace back to solid evidence. The reality is more individual than that. How much water you need depends on your body size, activity level, the climate you live in and what you eat. Living in Malta, where summers routinely hit 35°C and humidity is high, hydration matters more here than in most of Europe.

How Much Do You Actually Need?

The European Food Safety Authority recommends about 2 litres per day for women and 2.5 litres for men as a total water intake — and that includes water from food. Fruits, vegetables, soups and even coffee contribute to your fluid intake. So if you eat a Mediterranean diet rich in tomatoes, cucumbers, watermelon and soups, you're already getting a decent amount of water from food. In practice, most adults do well drinking around 1.5–2 litres of actual water per day on top of what they get from food. In Malta's summer heat, you'll need more — potentially 2.5–3 litres if you're active outdoors.

Signs You're Not Drinking Enough

The simplest check: look at your urine. Pale straw-coloured means you're well hydrated. Dark yellow or amber means you need more water. Other signs of mild dehydration include headaches, fatigue, difficulty concentrating, dry mouth and constipation. In Malta's heat, you might not notice you're sweating much because sweat evaporates quickly in dry air or gets absorbed by clothing. But you're still losing fluid. If you feel a headache coming on in the afternoon, try drinking a large glass of water before reaching for paracetamol — dehydration headaches are extremely common.

Does Coffee Dehydrate You?

No. This is one of the most persistent myths in nutrition. Caffeine is a mild diuretic, meaning it makes you urinate slightly more. But the water in your coffee more than compensates. A cup of coffee is still a net positive for hydration. Studies have confirmed that moderate coffee consumption (three to four cups per day) does not cause dehydration. So your morning cappuccino counts towards your fluid intake. That said, if you're drinking five or six espressos a day, the caffeine itself might cause other issues like anxiety or disrupted sleep, which is a separate conversation.

Water vs Sports Drinks vs Flavoured Water

For most people doing moderate exercise, plain water is all you need. Sports drinks (like Gatorade or Powerade) contain electrolytes and sugar, which are useful if you're exercising intensely for over an hour in the heat — think long-distance running, competitive cycling or an outdoor football match in a Maltese July. For a 30-minute gym session or a yoga class, water is fine. Flavoured waters often contain added sugar or artificial sweeteners. If you find plain water boring, add a slice of lemon, cucumber or fresh mint. It's cheaper, tastes better and has no additives.

Hydration Tips for Malta's Climate

Keep a reusable water bottle with you. Carry it in your car, your bag, your desk. If it's in front of you, you'll drink more without thinking about it. Start your day with a glass of water before your coffee. Eat water-rich foods: watermelon, oranges, grapes, cucumbers, tomatoes and lettuce are all above 90% water. If you're exercising outdoors in summer, drink before you're thirsty — by the time thirst kicks in, you're already mildly dehydrated. After intense exercise, consider adding a pinch of salt to your water or eating something salty to replace lost sodium.
