Heat and Health

Extremely hot weather is common in many parts of the world.Although hot weather just
makes most people hot,it can cause medical problems and death.
Health experts say that since the year 1900,extremely hot weather has killed more
people in the United States than any other natural event.One year一the unusually hot
summer of 1980一heat caused about 1,700 deaths in the United States.In 1995,more
than 600 people died in a similar heat wave in one city一Chicago.
To measure extreme heat,government weather experts have developed the Mean Heat
Index.It measures the average of how hot it is felt all day on an extremely hot day.Experts
say it is the total heat of a hot day or several hot days that can affect health.Several hot
days are considered a heat wave.Experts say heat waves often become deadly when the
nighttime temperature does not drop much from the highest daytime temperature.
The most common medical problem caused by hot weather is heat stress.It is also
least severe.For most people,the only result of heat stress is muscle pain.The pain is a
warning that the body is becoming too hot. Doctors say drinking water will help the pain
disappear after the body again has the right amounts of water and salt.For some people,
however,the result is much more serious.
For example,doctors say some people face a greatly increased danger from heat
stress.These people have a weak or damaged heart,high blood pressure,or other
problems of the blood system.Severe heat can help cause a heart attack or stroke.Health
experts say this is the most common cause of death linked to hot weather.

How many people died from heat in Chicago in 1995?
A: About 1700.
B: Nearly 1900.
C: Around 1100.
D: Over 600.
