Our bodies are made up of approximately 70 percent water. Water has many important functions in the body, including; regulating your body’s temperature, digesting food and excreting waste.
Your body loses water throughout the day when you sweat, breathe and urinate. It is important to replace the water you have lost to prevent yourself from becoming dehydrated.
Children are at a greater risk of dehydration than adults. This is because in relation to their size, children have a larger proportion of their skin available to lose sweat and be exposed to heat.
