Heat cramps often affect the muscle of the calves and arms. They typically take place when exercising heavily in a hot atmosphere and are painful, uncontrolled muscle spasms which can be prolonged. Low fluid intake can sometimes help to cause heat cramps.

What to do when suspecting heat cramps?

• Rest briefly.
• Cool down by drinking water with a teaspoon of salt, juice or an electrolyte-containing sports drink.
• Perform moderate stretching and gently massage the affected muscles.
• If the cramps continue for over an hour seek medical help.
