Water, an essential nutrient for hydrating your children

Water is the main constituent of the human body. It represents 60% of an adult’s body weight, and even more for a new-born baby (75%). Water has numerous essential roles in the human body. It acts as a building material; as a carrier for nutrients and waste products; in thermoregulation and as a lubricant and shock absorber.

To function properly, your children’s bodies has to recover the water lost during the day (through urine, sweat, breathing, and faeces) by consuming food and beverages. Therefore, to maintain the water balance, it is important to remind them that they should drink water regularly throughout the day . Daily water requirements vary according to age, gender, weather, physical activity… (1)

How can you make sure that your child drinks enough water?

Don’t wait until your child feels thirsty to give him or her water to drink. In fact, the sensation of thirst arises when the body has already lost more water than he has got. Thus, you can explain to your child that by the time he or she feels thirsty, a lack of hydration is already there.

Another tip is to look at the urine color. If it is dark-coloured, rather than pale yellow, that might mean that your child are not drinking enough*.

*The colour of the urine can be affected by certain foods, vitamin supplements or medical treatment
