Prevent Heat Illness: There were 7,415 heat-related deaths in the United States from 1999 to 2010, according to the Centers for Disease Control and Prevention (CDC). These preventable deaths illustrate how important preparation is during extreme temperatures. Whether you are swimming at the beach or lounging in the park, you should be prepared for extreme heat conditions. Stay Prepared: The CDC provides three easy steps to prevent heat-related illnesses: stay cool, stay hydrated and stay informed. This summer, make sure you have shade wherever you are going and have attire, like a sun hat or a thin, long-sleeved shirt, to avoid direct contact with the sun. Be sure to drink lots of water—more than you usually do. Your body quickly loses fluids in the summer more quickly, which can lead to illness.
