Who's At Risk
People most susceptible to heat cramps are those who are outdoors on a hot, humid day or those inside in a poorly ventilated area, particularly children, the elderly, or the obese. Children and the elderly show the fastest progression of symptoms and can collapse suddenly.

Those on certain medications can suffer from heat illness, as well, as medications can alter the way the body handles heat and sun. Those who drink alcohol before, during, or after vigorous activity are more susceptible to heat illness, as are people who do heavy work with inadequate fluid intake.
