Heat Cramp

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 nighttime leg cramps. Fluid and electrolyte loss often contribute to heat cramps.

Signs and Symptoms:

  • Painful spasms
  • Abnormal body posture
  • Grasping the affected area

If you suspect heat cramps…

  • Allow yourself rest from the heat 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
  • Attend medical assistance if you experience cramps for longer than an hour
