Heat emergencies

Alternative names:

heatstroke

Definition:

Heat emergencies fall into three categories: heat cramps, heat-exhaustion, and heatstroke (or sunstroke).

Considerations:

Heat illnesses are easily preventable--take necessary precautions in hot weather.

Children, elderly, and obese people are particularly at risk of developing heat illness. However, even a top athlete in superb condition can succumb to heat illness if he or she ignores the warning signs.

Without intervention and resolution of the problem, muscle cramps (caused by loss of salt from heavy sweating) can lead to heat-exhaustion (caused by dehydration) which can lead to heatstroke (which can cause shock, brain damage, and death).

Common causes:

  • Cardiovascular disease


  • Dehydration


  • Drug usage such as amphetamines, phenothiazines, and anticholinergics


  • Excess clothing


  • Exercise, prolonged or excessive


  • High temperatures or humidity


  • Lack of acclimatization


  • Sweat gland dysfunction


  • Alcohol use
