They regulate hydration, transmit nerve impulses, support muscle contraction and maintain acid-base balance.
If you don't get enough electrolytes, symptoms such as fatigue, dizziness, cramps, palpitations and even concentration problems may occur.
Why are they important in everyday life
Even without fasting, electrolytes are vital for:
- Functioning of the heartSodium and potassium control the heart rate.
- Muscle functionMagnesium prevents cramps and muscle fatigue.
- Nerve functionCalcium and magnesium support the transmission of nerve signals.
- Cellular hydrationElectrolytes allow water to enter cells properly.
Importance of electrolytes in intermittent fasting and fasting with water
During fasting, insulin levels drop, and the kidneys excrete more sodium and water. Accelerated fluid loss also leads to loss of potassium and magnesium.
The result? Common symptoms in the first days:
- Dizziness
- Fatigue
- Muscle cramps
- Headaches
Maintaining a minimum intake of electrolytes can prevent these problems and help the body tolerate the transition more easily.
