What causes muscle cramps?
Muscle cramps occur when muscles spasm uncontrollably. Any muscle can be affected, but cramps in the calf and foot muscles are very common.
While the exact cause of muscle cramps is unknown, there are a few factors that can increase your risk. These include:
- Being unfit
- A poor diet
- Muscle injury or fatigue
- Physical overexertion.
You could also be low in some electrolytes and minerals that help your muscles and nerves function such as potassium, sodium and magnesium. If you want to top up, good sources of potassium include bananas and avocados, leafy greens like kale and spinach and dairy products including milk and yoghurt. Leafy greens are also a great source of magnesium, along with lentils, chickpeas and nuts.
