These are probably some of the questions that you have as a parent when participating in physical activities with your children.
Humans are made up of 70% water. Our body loses water through breathing, urination, bowel movements and sweating throughout the day. Young athletes and children lose more body fluid due to sweating during training and physical activity, especially in our hot weather.
Sweating ensures that their core body temperature is maintained at an optimal level. However, losing a lot of body water also means that they must pay special attention consuming sufficient amounts of fluid to hydrate their bodies while having fun or training for a sport.
So be it playing ball games with your child or just simply having fun at the playground, it is important to ensure that your child is properly hydrated.
Hydration is important to prevent the occurrence of dehydration, especially in children due to their decreased ability to regulate their body temperature compared to adults. Dehydration is resulted from a negative fluid balance, whereby fluid intake is less than fluid loss, especially via sweating. Depending on his or her age, your child may also not be able to communicate the fact that they are feeling dehydrated.
When well-hydrated, there is improved physical and mental performance and optimal maintenance of heart rate and body temperature. Being hydrated will allow your child to perform at their best with improved concentration, thinking, cardiovascular function and overall well-being.
Hydration in children and young athletes can be slightly different compared to the adults in terms of what and how much they should drink. In general, children sweat less compared to the adults, which means that lesser sodium is being lost from sweat. Having said that, water should be the go-to drink for the young ones to consume. However, that’s not to say that they can’t have the occasional fruit juice (freshly squeezed of course) as a reward, with kids being kids.

There are a variety of fluids that can be taken at different stages of training or physical activity, and water is not the only solution! Although water is suitable in the initial stages of training or physical activity, other forms of fluids (i.e. milk) easily retain fluid in the body better. Milk is 90% water, contains more electrolytes than leading sport drinks, and contains proteins that help rehydration and muscle repair too!
Hydration is important for optimal performance and health, especially in the heat. Hydrating well does not only mean drinking water, but also knowing the quantity, timing and type of fluids that can affect the performance of an athlete. Young athletes and children should monitor their hydration status by looking at their volume and colour of urine produced.
They are also advised to sip regularly on water during the day, and hydrate during training or physical activity, using water and also sport drinks when training at intensity or longer than an hour. Cool fluids are best, especially in the heat. After exercise, re-hydrating with water and milk is best. With poor hydration habits come consequences which can influence well-being and performance.
So, the next time you are out having fun with your young ones, be sure to pack enough fluids and drink up regularly to ensure that you are both well hydrated!
