When it comes to keeping young athletes hydrated, one of the most common questions parents ask is:
Should my child drink water or an electrolyte drink during sport?
The answer isn't as simple as choosing one over the other. Both play an important role, and knowing when each is appropriate can help young athletes stay hydrated, perform at their best and recover well after exercise.
Let's look at the differences.
What is water?
Water is essential for life and should be every child's primary source of hydration.
It helps to:
- Regulate body temperature.
- Transport nutrients around the body.
- Support healthy brain function.
- Lubricate joints.
- Aid digestion.
- Replace fluids lost throughout the day.
For most children and for shorter sporting activities, water is all that's needed.
What are electrolytes?
Electrolytes are minerals that help the body function properly.
The main electrolytes include:
- Sodium
- Potassium
- Magnesium
- Calcium
These minerals help regulate fluid balance, support normal muscle function, assist nerve communication and contribute to maintaining hydration.
When children sweat during exercise, they lose both water and electrolytes. Replacing only the water may not always be enough during prolonged or intense activity.
Water vs electrolytes: What's the difference?
The biggest difference is what they replace.
Water replaces the fluid lost through sweat.
Electrolyte drinks replace both fluids and key minerals lost through sweating.
That's why electrolyte drinks are often recommended for longer sporting events or exercise in hot conditions.
When is water enough?
Water is usually the best choice when your child is:
- Playing sport for less than an hour.
- Participating in low to moderate intensity exercise.
- Attending PE classes.
- Playing casually with friends.
- Going about everyday activities.
For these situations, carrying a refillable water bottle and drinking regularly is usually all that's required.
When are electrolytes beneficial?
Electrolyte drinks can become more useful when young athletes are:
- Playing for longer than 60 to 90 minutes.
- Competing in tournaments with multiple games.
- Training several times in one day.
- Exercising in hot or humid conditions.
- Sweating heavily.
- Recovering between matches.
In these situations, replacing lost electrolytes alongside fluids may help support hydration and normal muscle function.
Can you drink too many electrolyte drinks?
Like any nutrition product, electrolyte drinks should be used appropriately.
They aren't intended to replace water throughout the day, and they aren't necessary for every sporting activity.
Water should remain the main source of hydration, with electrolyte drinks reserved for times when fluid and electrolyte losses are greater.
Signs your child may need more than water
Every child is different, but during prolonged exercise they may experience:
- Heavy sweating.
- Fatigue.
- Muscle cramps.
- Headaches.
- Feeling light-headed.
- Reduced concentration.
- Increased thirst.
These symptoms can have a range of causes, but maintaining good hydration before, during and after exercise is an important part of supporting performance and recovery.
Foods also contain electrolytes
Electrolytes don't only come from drinks.
Many whole foods naturally provide important minerals, including:
- Bananas
- Dairy foods
- Leafy green vegetables
- Nuts and seeds
- Potatoes
- Avocados
A balanced diet plays an important role in supporting active young athletes alongside good hydration habits.
Why we created DYVAL Perform
As parents of a young footballer, we spent years watching long training sessions, weekend tournaments and hot summer matches.
We wanted a hydration drink that provided key electrolytes without relying on unnecessary artificial colours or flavours.
When we couldn't find exactly what we were looking for, we created DYVAL Perform.
DYVAL Perform is a clean hydration drink formulated with key electrolytes, including calcium and magnesium, to help support hydration during longer or more demanding sporting activities.
It's designed for active young athletes across a wide range of sports, from football and netball to basketball, rugby, tennis and athletics.

Hydration tips for young athletes
To help your child stay hydrated:
- Drink water consistently throughout the day.
- Start sport already well hydrated.
- Take regular drink breaks during activity.
- Replace fluids after exercise.
- Eat a balanced diet rich in whole foods.
- Consider an electrolyte drink during prolonged or intense exercise, particularly in hot weather.
Small habits can make a big difference over the course of a sporting season.
Frequently Asked Questions
Is water better than electrolytes?
For everyday hydration and shorter activities, yes. Water is usually all that's needed.
For longer or more demanding exercise where significant sweating occurs, electrolyte drinks may help replace minerals lost through sweat.
Do kids need electrolyte drinks?
Most children don't need electrolyte drinks for everyday activity.
However, during extended training sessions, tournaments or sport played in hot weather, electrolyte drinks may help support hydration.
Can you mix water and electrolyte drinks?
Yes. Many young athletes drink water throughout the day and use an electrolyte drink during or after longer sporting activities when appropriate.
So, which is better: electrolytes or water?
The answer is that both have an important role.
Water is the foundation of healthy hydration and should be your child's everyday drink.
Electrolyte drinks become useful when exercise is longer, more intense or takes place in hot conditions where greater amounts of fluid and minerals are lost through sweat.
By understanding when each is appropriate, parents can help young athletes stay hydrated, recover well and feel ready for every training session and game.
