What is the Recommended Daily Water Intake - Importance of Water in Our Life

What is the recommended daily water intake?

Without enough water, the human body is soon unable to go on working. 

Our blood is mostly made of water.
Blood carries oxygen from our lungs and nutrients from our intestines to all parts of our bodies. Nutrients are the useful chemicals that we take from our food.
Water also helps to keep our muscles and joints running smoothly.

Some of this water is lost because we breathe it out. In cold weather, we can see the water vapor condensing in the cold air as it comes out of our mouths.
We lose water when we perspire and when we go to the toilet.
If we are ill, we often have a fever and perspire more than usual. 
This is why, if we are ill, the doctor may tell us to drink plenty of liquids.

Did you know that you could live without water for only about a week? 

You probably think your body feels firm and solid because it's full of strong bone and muscle.
But, in fact, about 65 per cent of your body is made up of water.
Because we lose water, we need to keep replenishing the water in our bodies.

We need about 2.5 quarts (2.4 liters) of water each day.
