Heat Cramps: First Aid

images (28)Heat cramps are painful, involuntary muscle spasms that usually occur during heavy exercise in hot environments. The spasms may be more intense and more prolonged than are typical night-time leg cramps. Inadequate fluid intake often contributes to heat cramps.

Muscles most often affected include those of your calves, arms, abdominal wall and back, although heat cramps may involve any muscle group involved in exercise.

If you suspect heat cramps

Rest briefly and cool down

Drink clear juice or an electrolyte-containing sports drink

Practice gentle, range-of-motion stretching and gentle massage of the affected muscle group

Don’t resume strenuous activity for several hours or longer after heat cramps go away

Call your doctor if your cramps don’t go away within one hour or so
