💧 The Importance of Adjusting Your Water Intake to Activity and Environment

Based on WHO Principles – Nutrients in Drinking Water (2005)

🌡️ Environment Affects Hydration Needs

Temperature and humidity have a significant influence on how much water your body requires. In hot or humid climates, you lose more fluids through sweat, meaning you need to drink more water. In cooler environments, water loss is lower — but proper hydration is still essential for organ function and metabolism.

🏃‍♀️ Physical Activity Increases Fluid Demand

If you're physically active — whether through exercise or outdoor work — your daily hydration needs will rise. Water helps maintain electrolyte balance, regulate body temperature, and support muscle recovery. Drink water before, during, and after physical activity to keep your performance and energy levels high.

🥗 Water Isn't the Only Source of Hydration

WHO also highlights that hydration doesn't come from drinking water alone. Foods like fruits, vegetables, and soups contribute significantly to your total daily fluid intake. This means that balanced nutrition plays an important role in staying hydrated.

💡 Listen to Your Body

You don't have to obsess over the "2-liter rule." Instead, pay attention to simple signs: clear urine, a lack of excessive thirst, and feeling refreshed are all indicators that you're well-hydrated.
