How much water do children need?


Our bodies are made of about 70 percent water – it’s what makes up the majority of our blood, digestive juices and sweat, and it’s found in our organs and muscle cells.

Water is used to metabolise fuel, regulate body temperature and digest food. To enable our bodies to carry out all of its functions in the day, water constantly moves about and is lost in the air we breathe, urine, blood loss, sweat and even tears. Children, in particular, need to make sure they re-hydrate, as water is the main way they regulate their body temperature.

Water contains no energy and in most States of Australia, tap water has been fortified with fluoride to help protect against tooth decay. Australia’s water supply is one of the safest and cheapest in the world so drinking tap is cost effective and good for your health.

How much water do children need?

The amount of water a child needs is influenced by the amount of activity they do, the weather temperature, and their diet and health. It’s always important to remind children to drink, but as a general guide, children up to 8 years of age should have a minimum of 4-5 cups of water a day. Children above 8 years old require at least 6-8 cups of water a day.
