Heat advisories and excessive heat warnings have been in effect for many days.  Heat is one of the leading weather-related killers in the United States, resulting in hundreds of fatalities each year.  The nonprofit Federal Alliance for Safe Homes offers the following safety tips to reduce the risk of illness from high temperatures.  The coolest part of the day is normally sunrise, so plan any necessary strenuous activity for the morning.  Stay indoors as much as possible.  If air conditioning is not available, stay on the lowest floor, out of the sun.  Drink plenty of water even if you don’t feel thirsty.  Avoid alcohol and caffeine as they can intensify the negative effect of heat on your body.  Wear lightweight, light-colored clothing to reflect some of the sun’s energy.  Never leave children, elderly or pets in the car even with the windows down.  Although the outside air temperatures may seem comfortable, temperatures inside a vehicle can rise 40 to 50 degrees and swiftly create deadly, oven-like conditions.  For information on protecting your family and home from severe weather, visit www.flash.org.
