Heat stroke killed over 200 people in 2011 and over 150 in 2012.  In 2011 almost forty related deaths occurred in Pennsylvania alone. The elderly are especially at risk for a variety of reasons. There are many medicines that interfere with the bodies ability to regulate temperature, many also inhibit perspiration. As we age the body begins to lose its ability to respond to temperature changes, coupled with any number of chronic medical conditions that can change the bodies natural reaction to heat and it can cause a life threatening situation.

WebMd describes heat stroke as a core body temperature greater than 105 degrees Fahrenheit, with complications involving the central nervous system that occur after exposure to high temperatures. Other common symptoms include nausea, seizures, confusion, disorientation, and sometimes loss of consciousness or coma.

Precautions to take to help avoid heat stroke are avoid becoming dehydrated. If participating in vigorous physical activities take frequent breaks.  Wearing loose light-colored clothing is an excellent choice.

Be knowledgeable of the signs of heat stroke. A few of the signs include dizziness, nausea, not sweating with your skin being flushed. Having difficulty breathing and a rapid pulse are among a few other signs.  For more signs and other information http://www.mayoclinic.org/diseases-conditions/heat-stroke/basics/symptoms/con-20032814.
