Understanding the Dangers of Heat-Related Illnesses

While Wednesday morning started out mild, “stifling” heat and dangerous humidity with heat indices as high as 110 degrees were in the forecast, with dewpoints expected to rise as the day goes on.

“Very high heat index levels, very hot and humid conditions,” NBC 5 Storm Team Meteorologist Alicia Roman said, as a heat advisory for all of Illinois and Indiana went into effect.

The Risks of Heat-Related Illnesses

Such high temperatures and soaring humidity levels can lead to severe heat-related illnesses, and even death, experts warned. In July 1995, a devastating, week-long heat wave struck Chicago, with high temperatures of 106 degrees and heat indices up to 120. More than 700 people died, according to officials.

Many of the illnesses carry symptoms that may not seem obvious.

Types of Heat-Related Illnesses

“The least [severe] is heat cramping,” Okubanjo said. “Where you get, like, cramping in your stomach muscles, leg muscles, shoulder muscles.” That’s usually due to dehydration or low electrolytes, Okubanjo said, “especially if you’re an athlete.

After that, there’s heat syncope.

“A fancy word for ‘passing out,’ because it’s too hot” Okubanjo said. “If that happens, that is concerning. You need to call 911.”

Heat exhaustion is more severe, Okubanjo said.

“That’s when you’re super sweaty. You’re drenched in sweat, you can barely talk, and barely stop to catch your breath. You’re really, really tired or fatigued,” Okubanjo said. Other symptoms include pale, clammy skin and muscle cramps.

How Humidity Affects the Body

“Humidity inhibits our bodies from cooling down,” NBC 5 Storm Team Meteorologist Kevin Jeanes explained. “Our bodies react by sweating more.”

If you don’t feel better in an hour, Okubanjo said, “you’re going to need to call 911, because you’re likely going into heat stroke, which is the most dangerous.”

Heat Stroke: The Most Dangerous Condition

Heat stroke is when your body temperature rises to over 104 degrees Fahrenheit.

“You can’t regulate your temperature,” Okubanjo said. “That’s a really scary thing.”

In heat stroke, you stop sweating, which means your body has stopped doing its job of trying to cool you off. The biggest symptom Okubanjo said to watch for, is confusion.

“They’re not making sense anymore,” Okubanjo said. “They’re slurring their speech. They could even have seizures. There’s sometimes nausea and vomiting, but the biggest thing, is that they’re confused. They’re not themselves. That’s really something to be concerned about.”

What to Do in Case of Heat-Related Illness

The best course of action, Okubanjo said, is to call 911.

“It’s better for us to determine if they’re in heat stroke, versus you waiting to see if they get better.”

Okubanjo went on to say that parents especially need to be attuned to warning signs in small children, since their communication is limited.

“If they’re not acting like themselves — they’re not wanting to eat, they’re not wanting to take their bottle, they’re vomiting, they’re not moving,” Okubanjo said. “A still baby is a scary baby.

According to the National Weather Service, the heat advisory will remain in effect through 10 p.m. Thursday

Conclusion

Heat-related illnesses are a serious concern, especially during periods of high temperatures and humidity. It’s essential to be aware of the symptoms and take prompt action if you or someone you know is experiencing any of them. By understanding the risks and taking necessary precautions, we can stay safe and healthy during the hot summer months.
