As temperatures continue to rise in Iowa, here are some things you can do to stay safe in the heat this summer:
What is the WBGT?
Understanding the WetBulb Globe Temperature (WBGT) and how it differs from the heat index can help you make the right decisions regarding staying outside in extreme heat.
The National Weather Service defines the WBGT as a measurement of the heat stress in direct sunlight. This takes into account temperature, humidity, wind speed, sun angle and cloud cover, whereas the heat index takes into consideration temperature and humidity calculated for shady areas.
Simply put, the WBGT offers a precise measurement of heat conditions for those performing strenuous activity or work outdoors. Paying attention to the WBGT can help protect you and your loved ones from serious heat-related health concerns such as heat exhaustion and heatstroke.
How to spot heat exhaustion
Heat exhaustion can occur by the body overheating, whether due to prolonged exposure to high temperatures or physical exertion in high temperatures for long periods of time.
Gone untreated, heat exhaustion can lead to severe cases of overheating in the body, such as heatstroke and, in extreme cases, death. Call emergency services right away if you or someone you know are losing consciousness, experiencing confusion or dizziness, and have a rapid pulse.
It is important to be aware of the signs of heat exhaustion. If you or someone near you is experiencing symptoms such as faintness, dizziness, copious sweating, muscle cramps, headaches or nausea, be sure to stop physical activity right away, seek out a cooler place, and drink plenty of water to rehydrate yourself.
In order to help prevent heat exhaustion, there are a variety of things you can do to stay safe.
Rod Donavon, a senior meteorologist at he National Weather Service office in Des Moines, recommends taking all the proper precautions during severe heat: “Drink plenty of water, find shade, and seek out air conditioning as much as possible.”
How to cool off
Cooling centers throughout the state offer free air conditioning and a place to rest and escape from the extreme heat.
Public libraries are a great free option for people searching for a place to relax and unwind out of the sun. If you’re searching for a pet-friendly location, The Animal Rescue League of Iowa’s main location in Des Moines offers a space to cool down with your furry friends. If you are unsure where a cooling center is near you, consider dialing 2-1-1 for information on local resources that will help you stay out of the heat.
If you plan on staying outside for prolonged periods this summer, consider checking the Iowa WBGT for recommendations on appropriate clothing, when to take breaks, and other information on how to stay safe in the sun.
