Role of electrolytes in hydration

What is the role of electrolytes in our body?

Electrolytes, those tiny electrically charged minerals like sodium, potassium, calcium and magnesium, are true heroes for our body! They play a crucial role in maintaining our health and well-being. So what makes them so special?

What is an electrolyte?

Electrolytes are important minerals that dissolve in our body's fluids. They help regulate water in our cells, keep our muscles working and transmit nerve signals. When we sweat, whether from heat or physical effort, we lose these precious minerals. This loss can lead to cramps, fatigue and even heart problems. Not very fun, right?

The main electrolytes and their roles

Electrolytes play a key role in several of our body's functions and are super important for keeping your health in top shape. Let's take a look at the specific roles of the four essential electrolytes!

Sodium (Na+)	Potassium (K+)	Calcium (Ca²+)	Magnesium (Mg²+)	Chloride (Cl-)

You'll find it in foods like salt, soups and pickled foods	It's the champion of regulating your heartbeat and muscle function. Bananas, potatoes and spinach are all good sources of potassium	It's the champion of regulating your heartbeat and muscle function. Bananas, potatoes and spinach are all good sources of potassium	This mineral helps produce energy, relax your muscles after exercise and keep your bones healthy. Think pumpkin seeds, nuts and dark chocolate!	Working alongside sodium, it helps stabilise the fluid balance in our body

What happens when we lose electrolytes?

When we lose water, we also lose these essential electrolytes. We then risk cramps, fatigue or even dizziness. A water loss equal to just 2% of our body weight can really affect how we feel! That's why it's important to stay well hydrated, especially after sweating.

How many electrolytes do we lose when we sweat?

Electrolyte losses vary depending on several factors, such as the intensity of physical activity and the temperature.

Sodium	Potassium	Magnesium	Chloride
Between 500 and 1,500 mg per litre of sweat	About 300 mg per litre of sweat	About 30 to 40 mg per litre of sweat	800 to 1,000 mg per litre of sweat

Key takeaways

• Electrolytes are hugely important for our body.
• When we sweat, we lose these minerals, which can cause cramps and fatigue.
• And don't forget to drink at least 1.5 to 2 litres of water a day to stay well hydrated!

Take care of yourself and remember to stay hydrated throughout the day! :)
