Hot, Humid Weather Can Pose Danger

As the summer begins and our days are starting to reach their normal hot temperatures, Polk County Health Department officials remind people that hot and humid conditions could be a dangerous combination. Make sure to check on friends and neighbors who have health conditions, especially those who stay at home or don't have air conditioning.

Rick Kozin, Polk County Health Department Director said, “High heat and humidity after several months of cooler weather can be a shock to the bodies of people who aren't accustomed to the heat yet, especially older adults, very young children and people with physical challenges. A rapid increase in body temperature is possible because the body cannot cool itself."

For the body to cool itself, the body sweats and the moisture evaporates off of the skin. When it is humid out, evaporation doesn’t take place and the body cannot cool as well. Your body temperature can increase to a fatal 106 degrees in as little as 10-15 minutes.

Many public places, like malls, libraries, senior centers, are air conditioned and are open to the public as daytime cooling centers. Two hours in air conditioning can significantly reduce the risk of health problems. For a full list of daytime cooling centers see http://www.polkcountyiowa.gov/health/.

Signs of heat exhaustion include feeling faint, body aches, stomach pain, nausea, and elevated body temperature. Heat stroke on the other hand is an emergency situation and can be life threatening. Signs and symptoms to watch for include shock, unconsciousness, and seizures.

Health Department officials remind people that while outside enjoying the summer weather drink a lot of cold water and take frequent breaks in the shade or air conditioning.  Do not wait until you are thirsty. If you are thirsty you are already dehydrated. Avoid caffeinated or alcoholic beverages and instead drink cold water throughout the day.

During periods of extended, uninterrupted high heat indexes Polk County Health Department will open an Emergency Overnight Cooling Shelter. Stay tuned to the local news or the Polk County Health Department’s website (www.polkcountyiowa.gov/health) for cooling shelter information.
