With the number of heat related emergency visits on the rise in American hospitals, the Centers for Disease Control and Prevention (CDC) has come out with a warning regarding outdoor activities in the hot sun.
The agency conducted a survey of 66 hospitals between 2001 and 2009 and found that nearly a quarter of heat related emergency visits to the hospitals were due to playing football in the hot sun. Football was the major reason for emergency visits of teenagers between 15 to 19 years of age with over 57 percent of such cases caused by playing outdoors.
Exercise came in at second place with 20.4 percent of all heat related cases caused due to jogging or walking in the sun. Of the total heat related medical cases, more than 90 percent of them had to be treated in emergency rooms.
The central United States and some parts of Canada are in the grip of a heat wave with temperatures often soaring over 100 degrees Fahrenheit (37 degree Celsius).
