Prevention

Avoid heat exhaustion by not engaging in strenuous activity in hot, humid environments. People who are not used to the heat should be particularly careful. Intersperse periods of rest in a cool environment with plenty of available fluids to drink. Avoid strenuous activities during the hottest part of the day.

Heat stroke often occurs in people who are unable to modify their environments: infants, the elderly, and bed-ridden people. People who are taking many types of blood pressure, allergy, or depression medication may also be particularly at risk and should avoid hot environments.

People in supervisory positions such as coaches, trainers, and lifeguards should be trained to specifically recognize signs of heat illness and what preventive measures to take.
