Heat Cramps - Heat cramps are painful spasms of muscles.
Heat cramps develop fairly rapidly due to a loss of fluid and salt due to sweating.
Heat cramps usually occur after heavy exercise or work outdoors in warm temperatures. Heat cramps usually occur in the legs and abdomen. To care for heat cramps, have the victim rest in a cool place. Have the victim sip cool water or a commercial sports drink. Lightly stretch the affected muscles and gently massage the area.
