Many areas of the Southwest United States experience hot weather during the summer, including much of California. Inland and desert portions of California frequently experience temperatures over 100 degrees during a typical summer. Even so, excessive heat conditions can impact residents resulting in countless heat-related injuries and several fatalities.
The major metropolitan areas of California are not immune from extreme heat. For example, during the extreme heat event that occurred in July 2006, Los Angeles County set an all time record high temperature of 119 degrees at Woodland Hills. Similarly, Fresno, in the Central Valley, experienced six consecutive days with temperatures above 110 degrees.
When high relative humidity combines with hot temperatures, the apparent temperature to the human body will be more severe. The heat index is calculated to explain the apparent temperature on the human body. Every individual is affected differently by exposure to hot temperatures, high humidity, and direct sun. However, human health scientists have determined that heat index values above 105 degrees pose the most serious risk to people. When you are planning outdoor activities, be sure to check the latest weather conditions, especially the heat index. The heat index will help you decide if precautionary measures should be taken, or if you should cancel your outdoor plans altogether.
Remember these safety tips when extreme heat threatens…
*Drink plenty of fluids
*Stay out of direct sunlight, or remain indoors with air-conditioning, if available
*Avoid alcohol and caffeinated beverages such as coffee, soda and tea
*Use wet cloths or blue cooler packs on the face, wrists or neck for a quick cool-down
*Remember your pets, they need plenty of fresh drinking water and shade to be protected from extreme heat
*If heat illness occurs, contact your physician or call 911 immediately!
People most susceptible to heat illness include children and the elderly, as well as people suffering from certain health conditions.
These individuals should be closely monitored during times of extreme heat. For example, check up on an elderly family member or neighbor
twice a day during periods of extreme heat.
