Feeling overheated in IL’s hot temps? Here’s how to distinguish 4 types of heat illness
As metro-east residents brace for temperatures creeping toward triple-digits this weekend, forecasters and health officials are reminding the public to be on the lookout for signs of heat-related illness.
While summer officially arrives this week, southern Illinois is already seeing temperatures in the upper 80s, and Belleville is expected to see a high of 97 degrees Fahrenheit by Friday, according to the latest forecast. The humidity will not be high enough to lead to an excessively high heat index in the area, however, the National Weather Service office in St. Louis reported Tuesday in a tweet on X.
During periods of hot weather, the Illinois Department of Public Health recommends individuals protect from heat-related illness by using the buddy system to check on vulnerable groups, like the elderly, bringing in outdoor pets, limiting time outside and other tactics to stay cool.
Here’s how to watch for and spot signs of heat-related illnesses, such as heatstroke and heat exhaustion, in your friends and neighbors, along with what to do should you encounter or experience them.
Signs of heatstroke
Heatstroke, also called sunstroke, is the most severe variety of heat-related illness.
This life-threatening condition occurs when the body’s internal temperature reaches 104 degrees Fahrenheit or higher, according to the Cleveland Clinic. Heat stroke requires immediate medical attention. Left untreated, it can result in organ failure, coma or death.
Heatstroke can develop over several days or just a few hours. Anyone can develop heatstroke under the right conditions, but infants and the elderly are particularly vulnerable because their bodies aren’t able to regulate temperature effectively.
Athletes, soldiers and people who do physical labor outdoors or in hot environments are also susceptible to heatstroke. Other risk factors, according to the Cleveland Clinic, include the following:
Consuming alcohol
Being male
Being dehydrated
Any drugs that affect the body’s ability to regulate temperature, such as diuretics, sedatives, tranquilizers or heart and blood pressure medications
Certain diseases that affect the ability to sweat, including cystic fibrosis
Having a sleep disorder or problems with your heart, lungs, kidneys, liver, thyroid or blood vessels
Wearing heavy or tight clothing, such as protective gear
Having a high fever
Obesity
Past history of heatstroke
Poor physical condition or lack of acclimatization
Symptoms of heatstroke can include:
Dry skin that doesn’t sweat (anhidrosis)
Problems with movement and coordination (ataxia)
Balance issues
Delirium (confusion and disorientation)
Dizziness
Hot, flushed skin or very pale skin
Low or high blood pressure
Low urine output
Rapid breathing or fast heart rate
Seizures
Fainting (also called heat syncope)
Weakness
Signs of heat exhaustion
Heat exhaustion is what your body experiences from excessive loss of water and salt — typically via heavily sweating.
According to the U.S. Centers for Disease Control and Prevention, the elderly, people with high blood pressure and people working outdoors or in hot environments are particularly vulnerable.
Untreated, heat exhaustion can lead to heat stroke. To treat heat exhaustion, the CDC recommends the following:
Remove the person from the heat and give them liquids, encourage frequent sips of cool water
Take them to a clinic or emergency room for medical evaluation and treatment. If that’s not immediately available, call 911
Stay with the person until help arrives
Remove unnecessary clothing, such as a shoes and socks
Cool the person with cold compresses or have them wash their head, face and neck with cool water
Symptoms of heat exhaustion include:
Headache
Nausea
Dizziness
Weakness
Irritability
Thirst
Excessive sweating
Elevated body temperature
Decreased urine output
Signs of heat cramps
According to the Cleveland Clinic, heat cramps are painful muscle spasms that occur when your body gets too hot. You lose important nutrients through your sweat, which causes your muscles to involuntarily tighten. Heat cramps can be a sign of heat exhaustion, so be aware if you feel your body locking up after some time outside.
Drinking something with electrolytes and cooling down your body should help resolve the cramping. Simply drinking large amounts of water does quickly help hydrate your body, but it also dilutes the nutrients in your body, which can cause cramping.
You might feel heat cramps in your:
Abdomen (stomach)
Arms
Hands
Feet
Legs
Rib cage
Shoulders
Signs of heat rash
As explained by the CDC, heat rash is caused by excessive sweating, particularly in hot and humid conditions.
Heat rash is treated by keeping the rash area dry and by moving out of the hot, humid environment. Powders can relieve irritation, but ointments and creams aren’t recommended, according to the CDC.
Symptoms include:
Red clusters of pimples or small blisters
The rash typically appears around the neck, upper chest, groin, under the breasts or in elbow creases
