Excessive heat can cause many problems

August 11, 2003

Here are some possible ill effects of exposure to excessive heat:

  • Heat cramps. Painful cramps involving abdominal muscles and extremities caused by intense, prolonged exercise in the heat and depletion of salt and water due to profuse sweating.

  • Heat syncope. Weakness, fatigue and fainting due to loss of salt and water in sweat and exercise in the heat. Predisposes to heat stroke.

  • Heat exhaustion (water depletion). Excessive weight loss, reduced sweating, elevated skin and deep body temperature, excessive thirst, weakness, headache and sometimes unconsciousness.

  • Heat exhaustion (salt depletion). Exhaustion, nausea, vomiting, muscle cramps and dizziness due to profuse sweating and inadequate replacement of body salts.

  • Heatstroke. An acute medical emergency related to thermoregulatory failure. Associated with nausea, seizures, disorientation and possible unconsciousness or coma. It may occur suddenly without being preceded by any other clinical signs. The individual is usually unconscious with a high body temperature and a hot dry skin (heatstroke victims, contrary to popular belief, may sweat profusely).
