As an individual sweats, water and <br />salts are lost by the body resulting in painful muscle cramps. The signs and symptoms of heat <br />cramps are as follows: <br />• severe muscle cramps, usually in the legs and abdomen; <br />• exhaustion, often to the point of collapse; and <br />• dizziness or periods of faintness. <br />First aid treatment includes shade, rest and fluid replacement. Normally, the individual should <br />recover within one-half hour. If the individual is not better within 30 minutes and the <br />temperature has not decreased, the individual should be transported to a hospital for medical <br />attention. <br />Heat exhaustion may occur in a healthy individual who has been exposed to excessive heat while <br />working or exercising. The circulatory system of the individual fails as blood collects near the <br />skin in an effort to rid the body of excess heat. The signs and symptoms of heat exhaustion are <br />as follows: <br />• rapid and shallow breathing; <br />• weak pulse; <br />• cold and clammy skin with heavy perspiration; <br />• skin appears pale; <br />ROUX ASSOCIATES HASP. 4/93 3425 Tracy Boulevard <br />Tracy, California <br />
