Why water is not enough – the importance of electrolytes in dehydration

Staying hydrated is crucial for both health and performance. But did you know that water alone isn't always enough – and in some cases can even worsen fluid imbalance in the body?

What happens when we sweat?

When we sweat, we not only lose water – we also lose important minerals such as:

• Sodium – the main electrolyte in the fluid outside the cells
• Potassium – important electrolyte inside cells
• Magnesium – contributes to normal muscle function and reduces fatigue

These substances are called electrolytes , and they are essential for nerves and muscles to function normally and for the body to be able to regulate fluid levels correctly.

What happens if we just replace fluid loss with water?

If you sweat a lot and only drink water, the concentration of sodium in your blood is diluted. This can create an imbalance between fluid and electrolytes , which can lead to:

• Fatigue and headache
• Muscle cramps
• Dizziness and confusion

In rare cases, it can cause what is known as hyponatremia , a condition in which the sodium level in the blood becomes dangerously low.

Who is at risk?

This is particularly relevant for:

• Long-distance runners and athletes
• People who exercise intensely in the heat
• People who fast or drink a lot of water without eating
• Occupational groups that work physically in hot environments
  
  

Fluid replacement with electrolytes

To counteract this, it is important to replenish electrolytes along with fluids. A fluid replacement supplement with carefully balanced amounts of sodium, potassium and magnesium can help to:

• Maintain normal fluid balance
• Support muscle and nerve function
• Reduce the risk of fatigue and cramps
  
  

Closing words

The body sweats out salt – not sugar . Simply replacing the loss with water can in some cases create a greater imbalance. Therefore, a sugar-free electrolyte powder can be a smart option for those of you who exercise, fast or sweat a lot.
