Special to the Chronicle

Even before summer officially begins, South Carolina temperatures and humidity are dangerously high.

According to the Centers for Disease Control (CDC), more than 600 people in the United States are killed by extreme heat every year.

Adults age 65 and older, those with chronic medical conditions, people who work outside, infants and children, and athletes are at higher risk during these hot months.

The American Red Cross recommends some steps you should take in hot weather:

• Hot cars can be deadly. Never leave children or pets in your vehicle. The inside temperature of the car can quickly reach 120 degrees.

• Stay hydrated by drinking plenty of fluids. Avoid drinks with caffeine or alcohol.

• Check on family, friends and neighbors who do not have air conditioning, who spend much of their time alone or who are more likely to be affected by the heat. If someone doesn’t have air conditioning, they should seek relief from the heat during the warmest part of the day in places like schools, libraries, theaters, malls, etc.

• Avoid extreme temperature changes.

• Wear loose-fitting, lightweight, light-colored clothing. Avoid dark colors because they absorb the sun’s rays.

• Slow down, stay indoors and avoid strenuous exercise during the hottest

part of the day.

• Postpone outdoor games

and activities.

• Use a buddy system when

working in excessive heat.

Take frequent breaks if

working outdoors.

• Check on animals frequently to ensure that

they are not suffering

from the heat. Make sure

they have plenty of cool

water.
