Heat Cramps

• Heat cramps are a mild form of heat exhaustion. Cramps occur when the body becomes overheated, due to high heat or humidity, exercising in hot conditions or dehydration. If you experience heat cramps, stop what you are doing and rest in a cool place, preferably in an air conditioned or shaded area. Drinking a sports drink will cool your body and replenish lost electrolytes. If you do not have a sports drink, consume plenty of cool water. If your symptoms do not go away or get worse, seek medical attention.
  
  

Heat Exhaustion

• Heat exhaustion is a more severe heat related condition. Symptoms may include sweating, dizziness, extreme tiredness and rapid or slowed pulse. If heat exhaustion is caused by water loss due to hot temperatures or overexertion, symptoms may include thirst, headache, weakness and loss of consciousness, according to WebMD. If your body has lost too much salt, you may experience queasiness and vomiting. Cramping and faintness may also occur. In addition, confusion and urine that appears very dark, are symptoms associated with heat exhaustion caused by salt depletion. If you experience any of these symptoms, immediately move to a cool location, preferably an air conditioned area indoors. Drink a sports drink or cool water. Lower your body temperature with a cool shower or bath, or by sponging off with a damp towel.
  
  

Heat Stroke

• If you are suffering from heat exhaustion and your body temperature reaches 104 degrees Fahrenheit, or your condition does not improve within an hour, seek immediate medical attention, as these may be signs of heat stroke. Heat stroke may cause brain damage. If left unattended, heat stroke can be fatal. Symptoms of heat stroke may include rapid breathing, difficulty speaking, seizures, coma or loss of consciousness and hallucinations, according to Mayo Clinic.
  
  

Prevention

• Heat related illness like heat exhaustion is preventable. Spend as much time as possible in a cool, air conditioned environment during hot and humid weather. Drink plenty of water or other fluids, and more if you are engaging in exercise or spending time outside when it is hot. Do not allow yourself to become thirsty. Wear comfortable, breathable clothing during hot weather. Take frequent breaks from the heat. Listen to your body and rest immediately if you experience heat cramps or the symptoms of heat exhaustion.
