Heat-Related Illness

 

Knowing when heat has really gotten to you.  This is Dr. Steven Andrew Davis, Speaking of Health.  It’s a spectrum of heat-induced lethargy which can quickly and unsuspectelly move into a condition know as heat exhaustion and perhaps even to heat stroke.  Exhaustion is important; heat stroke is a medical emergency.

 

The combination of high heat and high humidity is what brings on heat stroke and heat exhaustion.  Nine U.S. states have the highest age-adjusted death rates for heat-related illness:  Alabama, Arkansas, Arizona, Georgia, Kansas, Mississippi, Missouri, Oklahoma, and South Carolina.  The CDC points out, too, that heat also raises death rates from heart disease, stroke and lung disease too.

 

A quick refresher course:  heat stroke is a medical emergency, characterized by a body temperature of 105 degrees Fahrenheit or higher, typically bone-dry skin, and nervous system symptoms which can include disorientation, delirium, and coma.  Heat stroke can come on very rapidly and progress to a life-threatening illness within minutes.  Heat exhaustion can develop following exposure for several days to high temperatures and inadequate balance or replacement of fluids and blood minerals.  “Heat exhaustion is characterized by dizziness, weakness, and fatigue and may be sufficiently severe to require hospitalization.”

 

Remember:  heat-related illness doesn’t always happen to someone else.  It can occur in the very young and the very old in virtually of the country.  Speaking of Health, I’m Dr. Steven Andrew Davis for CBS News.  For a copy of this script and journal reference, access our web site, www.speakingofhealth.com.
